A signal word DANGER, WARNING, or CAUTION is used with the safety-alert symbol. DANGER identifies the most serious hazards.

DANGER or WARNING safety signs are located near specific hazards. General precautions are listed on CAUTION safety signs. CAUTION also calls attention to safety messages in this manual.

Follow Safety Instructions

Safety Messages

Carefully read all safety messages in this manual and on your machine safety signs. Keep safety signs in good condition. Replace missing or damaged safety signs. Be sure new equipment components and repair parts include the current safety signs. Replacement safety signs are available from your John Deere dealer.

There can be additional safety information contained on parts and components sourced from suppliers that is not reproduced in this operator′s manual.

Learn how to operate the machine and how to use controls properly. Do not let anyone operate without instruction.

Keep your machine in proper working condition. Unauthorized modifications to the machine may impair the function and/or safety and affect machine life.

If you do not understand any part of this manual and need assistance, contact your John Deere dealer.

Prevent Machine Runaway

Machinery Runaway

Avoid possible injury or death from machinery runaway.

Do not start engine by shorting across starter terminals. Machine will start in gear if normal circuitry is bypassed.

NEVER start engine while standing on ground. Start engine only from operator’s seat, with transmission in neutral or park.

Operating the Tractor Safely

You can reduce the risk of accidents by following these simple precautions:

Use your tractor only for jobs it was designed to perform, for example, pushing, pulling, towing, actuating, and carrying a variety of interchangeable equipment designed to conduct agricultural work. This tractor is not intended to be used as a recreational vehicle.

Read this operator’s manual before operating the tractor and follow operating and safety instructions in the manual and on the tractor.

Follow operation and ballasting instructions found in the operator’s manual for your implements/attachments, such as front loaders

Make sure that everyone is clear of machine, attached equipment, and work area before starting engine or operation. Keep hands, feet, and clothing away from power-driven parts

Driving Concerns

Never get on or off a moving tractor.

Keep all children and nonessential personnel off tractors and all equipment.

Never ride on a tractor unless seated on a John Deere approved seat with seat belt.

Keep all shields/guards in place.

Use appropriate visual and audible signals when operating on public roads.

Move to side of road before stopping.

Reduce speed when turning, applying individual brakes, or operating around hazards on rough ground or steep slopes.

Couple brake pedals together for road travel.

Pump brakes when stopping on slippery surfaces.

Safety Fall Off Tractor
Safety PTO

Towing Loads

Be careful when towing and stopping heavy loads. Stopping distance increases with speed and weight of towed loads, and on slopes. Towed loads with or without brakes that are too heavy for the tractor or are towed too fast can cause loss of control.

Consider the total weight of the equipment and its load.

Hitch towed loads only to approved couplings to avoid rearward upset.

Parking and Leaving the Tractor

Before dismounting, shut off SCVs, disengage PTO, stop engine, lower implements/attachments to ground and securely engage park mechanism, including the park pawl and park brake. In addition, if tractor is left unattended, remove key. Leaving transmission in gear with engine off will NOT prevent the tractor from moving.

Never go near an operating PTO or an operating implement.

Wait for all movement to stop before servicing machinery.

Common Accidents

Unsafe operation or misuse of the tractor can result in accidents. Be alert to hazards of tractor operation.

The most common accidents involving tractors:

Tractor rollover

Collisions with motor vehicles

Improper starting procedures

Entanglement in PTO shafts

Falling from tractor

Crushing and pinching during hitching

Operating the Loader Tractor Safely

Loader Tractor

When operating a machine with a loader application, reduce speed as required to ensure good tractor and loader stability.

To avoid tractor rollover and damage to front tires and tractor, do not carry load with your loader at a speed over 10 km/h (6 mph).

To avoid tractor damage do not use a front loader or a sprayer tank if the tractor is equipped with a 3 Meter Front Axle.

Never allow anyone to walk or work under a raised loader.

Do not use loader as a work platform.

Do not lift or carry anyone on loader, in bucket, or on implement or attachment.

Lower loader to ground before leaving operators station.

The Rollover Protective Structure (ROPS) or cab roof, if equipped, may not provide sufficient protection from load falling onto the operators station. To prevent loads from falling onto the operators station, always use appropriate implements for specific applications (that is, manure forks, round bale forks, round bale grippers, and clampers).

Ballast tractor in accordance to Ballast Recommendations in PREPARE TRACTOR section.

Passenger Seat

Use Seat Belt

The passenger seat is intended only for transport of a passenger in on-road operations (i.e. transport from farm to field).

If it is necessary to transport a passenger, the passenger seat is the only means of transport of a passenger condoned by John Deere.

Use Safety Lights and Devices

Prevent collisions between other road users, slow moving tractors with attachments or towed equipment, and self-propelled machines on public roads. Frequently check for traffic from the rear, especially in turns, and use turn signal lights.

Use headlights, flashing warning lights, and turn signals day and night. Follow local regulations for equipment lighting and marking. Keep lighting and marking visible, clean, and in good working order. Replace or repair lighting and marking that has been damaged or lost. An implement safety lighting kit is available from your John Deere dealer.

Towing Trailers/Implements Safely (Mass)

Towing trailers/implements safely (mass)

Stopping distance increases with speed and mass of trailer/implement, and when transporting on slopes. Towed mass with or without brakes that is too heavy for the tractor or is towed too fast can cause loss of control. Consider the total weight of the equipment and its load.

Tow Towed Mass Safely

Maximum design speed

There may be legal limits in force that restrict travel speeds to figures lower than those quoted here.

Use additional caution when towing loads under adverse surface conditions, when turning, and on inclines.

Use Caution On Slopes and Uneven Terrain

Avoid holes, ditches, and obstructions which cause the tractor to tip, especially on slopes. Avoid sharp uphill turns. Driving forward out of a ditch, mired condition, or up a steep slope could cause tractor to tip over rearward. Back out of these situations if possible.

Danger of overturn increases greatly with narrow tread setting, at high speed.

Not all conditions that can cause a tractor to overturn are listed. Be alert for any situation in which stability may be compromised.

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution

Never drive near the edge of a gully, drop-off, ditch, steep embankment, or a body of water. The machine could suddenly roll over if a wheel goes over the edge or the ground caves in

Choose a low ground speed so you will not have to stop or shift while on a slope.

Avoid starting, stopping or turning on a slope. If the tires lose traction, disengage the PTO and proceed slowly, straight down the slope.

Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the machine to roll over.

Freeing a Mired Machine

Tractor Tipping

Attempting to free a mired machine can involve safety hazards such as the mired tractor tipping rearward, the towing tractor overturning, and the tow chain or tow bar (a cable is not recommended) failing and recoiling from its stretched condition.

Back your tractor out if it gets mired down in mud. Unhitch any towed implements. Dig mud from behind the rear wheels. Place boards behind the wheels to provide a solid base and try to back out slowly. If necessary, dig mud from the front of all wheels and drive slowly ahead.

If necessary to tow with another unit, use a tow bar or a long chain (a cable is not recommended). Inspect the chain for flaws. Make sure all parts of towing devices are of adequate size and strong enough to handle the load.

Always hitch to the drawbar of the towing unit. Do not hitch to the front pushbar attachment point. Before moving, clear the area of people. Apply power smoothly to take up the slack: a sudden pull could snap any towing device causing it to whip or recoil dangerously.

Avoid Backover Accidents

Avoid Backover Accidents

Before moving machine, be sure that all persons are clear of machine path. Turn around and look directly for best visibility. Use a signal person when backing if view is obstructed or when in close quarters.

Do not rely on a camera to determine if personnel or obstacles are behind the machine. The system can be limited by many factors including maintenance practices, environmental conditions, and operating range.

Handle Fluids Safely—Avoid

Fires

Avoid Fires

When you work around fuel, do not smoke or work near heaters or other fire hazards.

Store flammable fluids away from fire hazards. Do not incinerate or puncture pressurized containers.

Make sure machine is clean of trash, grease, and debris.

Do not store oily rags; they can ignite and burn spontaneously.

Handling Batteries Safely

Caution

Caution

Battery gas can explode. Keep sparks and flames away from batteries. Use a flashlight to check battery electrolyte level.

Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer.

Always remove grounded (-) battery clamp first and replace grounded clamp last.

Sulfuric acid in battery electrolyte is poisonous and strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes.

Avoid hazards by:

Filling batteries in a well-ventilated area

Wearing eye protection and rubber gloves

Avoiding use of air pressure to clean batteries

Avoiding breathing fumes when electrolyte is added

Avoiding spilling or dripping electrolyte

Using correct battery booster or charger procedure.

If acid is spilled on skin or in eyes:

1. Flush skin with water.

2. Apply baking soda or lime to help neutralize the acid.

3. Flush eyes with water for 15 30 minutes. Get medical attention immediately.

If acid is swallowed:

1. Do not induce vomiting.

2. Drink large amounts of water or milk, but do not exceed 2 L (2 qt.).

3. Get medical attention immediately.

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Prepare for Emergencies

First Aid Kit

Be prepared if a fire starts.

Keep a first aid kit and fire extinguisher handy.

Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.

Avoid High-Pressure Fluids

Inspect hydraulic hoses periodically – at least once per year – for leakage, kinking, cuts, cracks, abrasion, blisters, corrosion, exposed wire braid or any other signs of wear or damage.

Replace worn or damaged hose assemblies immediately with John Deere approved replacement parts.

Escaping fluid under pressure can penetrate the skin causing serious injury.

Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.

Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available in English from Deere & Company Medical Department in Moline, Illinois, U.S.A., by calling 1-800-822-8262 or +1 309-748-5636.

Service Cooling System Safely

Cooling System

Explosive release of fluids from pressurized cooling system can cause serious burns.

Shut off engine. Only remove filler cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely.

High Pressure

Remove Paint Before Welding or Heating

Toxic Fumes

Avoid potentially toxic fumes and dust.

Hazardous fumes can be generated when paint is heated by welding, soldering, or using a torch.

Remove paint before heating:

Remove paint a minimum of 100 mm (4 in.) from area to be affected by heating. If paint cannot be removed, wear an approved respirator before heating or welding.

If you sand or grind paint, avoid breathing the dust. Wear an approved respirator.

If you use solvent or paint stripper, remove stripper with soap and water before welding. Remove solvent or paint stripper containers and other flammable material from area. Allow fumes to disperse at least 15 minutes before welding or heating.

Avoid potential fire or explosion hazards from flammable materials and vapors near the exhaust. Keep exhaust outlet away from people and anything that can melt, burn, or explode.

Closely monitor machine and surrounding area for smoldering debris during and after exhaust filter cleaning.

Adding fuel while an engine is running can create a fire or explosion hazard. Always stop engine before refueling machine and clean up any spilled fuel.

Always make sure that engine is stopped while hauling machine on a truck or trailer.

Contact with exhaust components while still hot can result in serious personal injury.

Avoid contact with these components until cooled to safe temperatures.

If service procedure requires engine to be running:

Only engage power-driven parts required by service procedure

Ensure that other people are clear of operator station and machine

Keep hands, feet, and clothing away from power-driven parts.

Always disable movement (neutral), set the parking brake or mechanism and disconnect power to attachments or tools before leaving the operator’s station.

Shut off engine and remove key (if equipped) before leaving the machine unattended.

Read Operator Manuals for ISOBUS Implements

In addition to GreenStar Applications, this display can be used as a display device for any implement that meets ISO 11783 standard. This includes capability to control ISOBUS implements. When used in this manner, information and implement control functions placed on the display are provided by the implement and are the responsibility of the implement manufacturer. Some of these implement functions could provide a hazard either to the Operator or a bystander. Read the operator manual provided by the implement manufacturer and observe all safety messages in manual and on implement prior to use.

ISOBUS refers to the ISO Standard 11783

Use Steps and Handholds Correctly

Use Handholds and Steps

Prevent falls by facing the machine when getting on and off. Maintain 3-point contact with steps, handholds, and handrails.

Use extra care when mud, snow, or moisture present slippery conditions. Keep steps clean and free of grease or oil. Never jump when exiting machine. Never mount or dismount a moving machine.

Use Seat Belt Properly

Use a Seat Belt

Use a seat belt when you operate with a roll-over protective structure (ROPS) or cab to minimize chance of injury from an accident such as an overturn.

Do not use a seat belt if operating without a ROPS or cab.

Replace entire seat belt if mounting hardware, buckle, belt, or retractor show signs of damage.

Inspect seat belt and mounting hardware at least once a year. Look for signs of loose hardware or belt damage, such as cuts, fraying, extreme or unusual wear, discoloration, or abrasion. Replace only with replacement parts approved for your machine. See your John Deere dealer.

Park Machine Safely

Remove the Key

Before working on the machine:

Lower all equipment to the ground. Stop the engine and remove the key. Disconnect the battery ground strap.

Hang a "DO NOT OPERATE" tag in operator station.

Use Proper Lifting Equipment

Proper Lifting Equipment

Lifting heavy components incorrectly can cause severe injury or machine damage.

Follow recommended procedure for removal and installation of components in the manual.

Construct Dealer-Made Tools Safely

Construct Dealer-Made Tools Safely

Faulty or broken tools can result in serious injury. When constructing tools, use proper, quality materials, and good workmanship.

Do not weld tools unless you have the proper equipment and experience to perform the job.

Support Machine Properly

Support Properly

Always lower the attachment or implement to the ground before you work on the machine. If the work requires that the machine or attachment be lifted, provide secure support for them. If left in a raised position, hydraulically supported devices can settle or leak down.

Do not support the machine on cinder blocks, hollow tiles, or props that may crumble under continuous load. Do not work under a machine that is supported solely by a jack. Follow recommended procedures in this manual.

When implements or attachments are used with a machine, always follow safety precautions listed in the implement or attachment operator′s manual.

Work in Clean Area

Clean Work Area

Before starting a job:

Clean work area and machine.

Make sure you have all necessary tools to do your job. Have the right parts on hand.

Read all instructions thoroughly; do not attempt shortcuts.

Illuminate Work Area Safely

Work Area Safely

Illuminate your work area adequately but safely. Use a portable safety light for working inside or under the machine. Make sure the bulb is enclosed by a wire cage. The hot filament of an accidentally broken bulb can ignite spilled fuel or oil.

Service Machines Safely

Moving Parts

Tie long hair behind your head. Do not wear a necktie, scarf, loose clothing, or necklace when you work near machine tools or moving parts. If these items were to get caught, severe injury could result.

Remove rings and other jewelry to prevent electrical shorts and entanglement in moving parts.

Service Accumulator Systems Safely

Hydraulic Accumulator

Escaping fluid or gas from systems with pressurized accumulators that are used in air conditioning, hydraulic, and air brake systems can cause serious injury. Extreme heat can cause the accumulator to burst, and pressurized lines can be accidentally cut. Do not weld or use a torch near a pressurized accumulator or pressurized line.

Relieve pressure from the pressurized system before removing accumulator.

Relieve pressure from the hydraulic system before removing accumulator. Never attempt to relieve hydraulic system or accumulator pressure by loosening a fitting.

Accumulators cannot be repaired.

Service Tires Safely

Explosive Tire and Rim Parts

Explosive separation of a tire and rim parts can cause serious injury or death.

Do not attempt to mount a tire unless you have the proper equipment and experience to perform the job.

Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel.

When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available.

Check wheels for low pressure, cuts, bubbles, damaged rims, or missing lug bolts and nuts.

Use Proper Tools

Proper Tools

Use tools appropriate to the work. Makeshift tools and procedures can create safety hazards.

Use power tools only to loosen threaded parts and fasteners.

For loosening and tightening hardware, use the correct size tools. DO NOT use U.S. measurement tools on metric fasteners. Avoid bodily injury caused by slipping wrenches.

Service Front-Wheel Drive Tractor Safely

Support Front and Rear Wheels

When servicing front-wheel drive tractor with the rear wheels supported off the ground and rotating wheels by engine power, always support front wheels in a similar manner. Loss of electrical power or transmission/ hydraulic system pressure will engage the front driving wheels, pulling the rear wheels off the support if front wheels are not raised. Under these conditions, front drive wheels can engage even with switch in disengaged position.

Avoid Eye Contact With Radar

Avoid Eye Contact With Radar

Radar ground speed sensor emits a very low intensity microwave signal. It will not cause any ill effects during normal use. Although intensity is low, DO NOT look directly into face of sensor while in operation, to avoid any possible eye damage.

Roll-Over Protective Structure

Make certain all parts are reinstalled correctly if the roll-over protective structure (ROPS) is loosened or removed for any reason. Tighten mounting bolts to proper torque.

The protection offered by ROPS will be impaired if ROPS is subjected to structural damage, is involved in an overturn incident, or is in any way altered by welding, bending, drilling, or cutting. A damaged ROPS should be replaced, not reused.

The seat is part of the ROPS safety zone. Replace only with John Deere seat approved for your tractor.

Any alteration of the ROPS must be approved by the manufacturer.

Replace Safety Signs

Safety Signs

Replace missing or damaged safety signs. See the machine operator’s manual for correct safety sign placement.

Replace Safety Signs

Safety Signs

Replace missing or damaged safety signs. Use this operator’s manual for correct safety sign placement.

There can be additional safety information contained on parts and components sourced from suppliers that is not reproduced in this operator′s manual.

Dispose of Waste Properly

Recycle Waste

Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used with John Deere equipment include such items as oil, fuel, coolant, brake fluid, filters, and batteries.

Use leakproof containers when draining fluids. Do not use food or beverage containers that may mislead someone into drinking from them.

Do not pour waste onto the ground, down a drain, or into any water source.

Air conditioning refrigerants escaping into the air can damage the Earth’s atmosphere. Government regulations may require a certified air conditioning service center to recover and recycle used air conditioning refrigerants.

Inquire on the proper way to recycle or dispose of waste from your local environmental or recycling center, or from your John Deere dealer.

Electronic Control Unit

[1]IMPORTANT:

Do not open control unit and do not clean with a high pressure spray. Moisture, dirt and other contaminants may cause permanent damage.

Control units are not repairable; replace only if indicated in the diagnostic procedure.

[2] - Since control units are the components LEAST likely to fail, isolate failure before replacing by completing the diagnostic procedure.

[3] - The wiring harness terminals and connectors for electronic control units are repairable.

[4]IMPORTANT:

Misleading diagnostic messages and poor performance may occur if an electronic control unit is not programmed identical to the original controller.

Before putting back into service, verify the control unit is programmed identical to the original controller.

Welding Near Electronic Control Units

Do not jump-start engines with arc welding equipment. Currents and voltages are too high and may cause permanent damage. Disconnect the negative (-) battery cable(s).

IMPORTANT:

Keep terminals clean and free of foreign debris. Moisture, dirt and other contaminants may cause the terminals to erode over time and not make a good electrical connection.

If a connector is not in use, put on the proper dust cap or an appropriate seal to protect it from foreign debris and moisture.

[2] -

IMPORTANT:

Do not probe through the wire insulation or through the back of the connector. Do not insert items such as paper clips or wires into connector terminals.

Make measurements on a connector terminal using JDG10466 Flex Probe Kit in SERVICEGARD.

→NOTE:

This reference is a guideline for troubleshooting problems that still exist after standard diagnostics have been performed. These problems are typically due to specific operating conditions or intermittent failures. Depending on the situation, some or all of the following may be important.

General Information

Terminals are typically made from a base metal that is plated with tin, gold, or an alloy. The plating material helps protect the base metal of the terminal from corroding. There are two main varieties of terminals; pins (male) and sockets (female). Pins are inserted into sockets and in this way create an electrical connection between cables or electrical devices. Sockets typically contain one or more contact springs which provide firm contact points with the pin. Scraping the layer of corrosion from the terminal also removes any remaining plating material, resulting in a rapid reappearance of the corrosion.

General Information - Electrical System, Troubleshooting Unsolved Problems

→NOTE:

This reference is a guideline for troubleshooting problems that still exist after standard diagnostics have been performed. These problems are usually caused by certain operating conditions, by intermittent malfunctions, or, in rare cases by a failed control unit. Depending on the situation, some or all of the following information may be of importance.

Problems caused by certain operating conditions

Review all recorded codes and consult with operator to determine operating and vehicle conditions when the problem occurs. Write down details.

1. Does code/problem occur at the same time as other problems?

2. Does code/problem occur when vehicle is warm or cold?

3. Does code/problem occur during field or transport operation?

4. Does code/problem occur while performing a specific action such as shifting, turning, braking, operating certain hydraulics?

5. When did code/problem first appear? Has service work been carried out recently? (If yes, inspect areas of maintenance for inadvertent damage or improper installations.)

Attempt to recreate code/problem based on conditions. If possible, repeat operational or system checks, electrical, hydraulic or mechanical checks under these conditions.

Problems caused by intermittent electrical failure

→NOTE:

Intermittent electrical failures are caused by wiring harness, terminal or connector problems.

1. Inspect all connectors and terminals of related circuits.

2. Check if harnesses or connectors are obstructed by mechanical parts.

3. Inspect harnesses for missing or improperly installed clamps or bands. Wiring harnesses that are too loose or too tight can cause worn or damaged cables.

4. Inspect mechanical linkages for proper operating condition.

Problems caused by failed control units

→NOTE:

Before replacing control unit, review all tests. Control units are the least likely cause of failure!

1. If all checks have been performed and no problems have been identified, check the power supply circuit and ground circuit. Power supply inputs must not deviate from battery voltage by more than 1 volt, and ground circuits must have a resistance of less than 1.0 ohm in relation to the ground point of the vehicle.

2. Inspect all connectors and terminals of associated control units.

General Information - Electrical System, Worksheet for Circuit/Harness Test

Circuit tests must be carried out if component testing on an electrical component in the circuit fails to identify a problem and:

active diagnostic trouble codes indicate there is a problem in the relevant circuit. saved diagnostic trouble codes that indicate a problem in the relevant circuit keep re-appearing. problems occur with a function associated with the relevant circuit.

→NOTE:

In the event of occasional circuit problems (loose contacts), it may be possible to use the beep mode of the relevant control unit to identify the fault. All the circuits of components that are marked “BEEP” in the Summary of Addresses for the relevant control unit can be checked using the beep mode of the control unit. For more information on the beep mode, see “Test Procedure in the Event of Occasional Problems” for the relevant control unit in the Group of the relevant circuit in Section 240.

The worksheet below allows circuits to be checked logically, with the technician naming all the relevant components and noting the steps taken. The list can be used to prove what work has been done; if the problem cannot be solved, the worksheet may be requested by the relevant after-sales service office.

General Information - Electrical System, Visual Check

If a customer reports a problem, perform a visual check of the electrical system before starting the tractor.

[1] - Check for frayed leads.

[2] - Check for missing or worn insulation; this can point to a wiring problem.

[3] - Check for loose or broken connections and leads:

[4] - Check battery for:

Loose or corroded terminal connections

Loose cable clamps/ties or battery posts

Dirt

Moisture

Cracked case

Correct electrolyte level

[5] - Check the alternator belt tension.

[6] - Check for overheated components five minutes after the engine has been shut off. Often there will be the smell of burnt insulation. Place your hand on the alternator. The presence of heat after the engine has been off for some time is a sure sign of a charging circuit problem.

[7] - If the visual check does not isolate a possible problem, but the results do not indicate that the engine should not be started, turn the ignition key to the IGN position. Check the accessory circuits, indicator lights, etc. Do these individual parts work? Look for sparks or smoke as signs of shorts.

[8] - Start the engine. Check all indicators for proper operation; determine if the system is charging or discharging.

[9] - In short, check for any abnormal conditions.

Many electrical faults cannot be identified easily even when the engine is started. For this reason the electrical system should be systematically and completely checked.

General Information - Electrical System, Electrical Circuit Malfunctions

Electrical circuit malfunction areas

Other malfunctions

There are only four circuit malfunctions:

High-resistance circuit ( GO TO 1 ).

Open circuit ( GO TO 1 ).

Grounded circuit ( GO TO 2 ).

Shorted circuit ( GO TO 3 ).

There are only three sections in a simple circuit where these malfunctions occur: Before the controlling switch (A), between the controlling switch (A) and the load (B), and after load (B).

Component malfunctions can easily be confused with circuit malfunctions. Therefore, care must be exercised when isolating the cause of the problem.

Example: A component does not operate before disconnecting an electrical connection, but it operates after reconnecting the connector. Cause: High resistance created a voltage drop at the connector terminals resulting in insufficient power supply to the component.

terminals, wire gauge too small or partially broken leads).

An open circuit results in no component operation because the circuit is incomplete (e.g. broken lead, terminals disconnected, open protective device on switch).

To isolate the location of a "high resistance" or "open circuit":

[1] - Turn controlling switch (C) ON and connect load (I) to the circuit. Check the voltage at an easily accessible point between (D) and (H).

If voltage is low, move toward voltage source (A) to locate point of voltage drop.

→NOTE:

The example shows high resistance between (D) and (F) and an open circuit between (F) and (G).

If voltage is correct, move toward load (I) and ground terminal (J) to locate voltage drop.

[2] - Repair as required.

Result:

NO:Repeat test procedure after repair.

YES:See procedure for grounded circuit: GO TO 2 . See procedure for shorted circuit: GO TO 3 .

( 2 ) Grounded circuit

Action:

Grounded circuit

E Component terminal

F Grounded circuit G Component terminal

H Lamp

A grounded circuit results in no component operation and opening of the fuse or circuit breaker (e.g. power lead contacting ground).

To isolate the location of a grounded circuit:

[1] - With controlling switch (D) OFF, check for continuity to ground between (C) and (D).

If there is continuity, there is a grounded circuit between (C) and (D). Repair circuit.

If there is no continuity, go to step 2.

[2] - Disconnect load (H) at (G).

[3] - With controlling switch (D) OFF, check continuity to ground between (D) and (F).

If there is continuity, there is a grounded circuit between (E) and (F). Repair circuit.

→NOTE:

In this example, the circuit is grounded between (E) and (F).

Result:

NO:Repeat test procedure after repair.

YES:See procedure for shorted circuit: GO TO 3 .

( 3 ) Shorted circuit

A shorted circuit usually results in two components operating even though only one of two switches is turned on (e.g. improper wire-to-wire contact). Components can also become shorted. However, shorted components will usually open the circuit protection device.

To isolate the location of a shorted circuit:

[1] - Turn switch (A) ON for correct lamp (B) to operate.

[2] - Start at controlling switch (D) of lamp (I) that should not be operating and disconnect the wire at terminal (E).

[3] - Follow circuit and disconnect wire at connectors (F, G or H) until lamp (I) stops operating.

[4] - The short or improper connection must be between the last two locations where the wire was disconnected. In this example, it is between (F) and (G).

[5] - Repair circuit as follows:

Wires not in an insulating tube: Wrap individual wire with electrical tape or replace the damaged wire and band as required.

Wires in an insulating tube: If hot spots exist in shorted area of the insulating tube, replace harness. If hot spots are not noticeable, install a new wire of proper gauge between the last two connections. Band wire to outside of harness.

Result:

NO:Repeat test procedure after repair.

General - Electrical System, Test for Open Circuit under Load

→NOTE:

With the tester, the electrical line and the connector is tested for an open circuit and high resistance with and without load.

General - Regions and Country Versions

Regions

LEGEND:

Region 1 China, India, South and East Asia, Africa except for North Africa

Region 2 Europe, GUS States including Russia, North Africa, Near and Middle East

Region 3 South America, Central America

Region 4 North America, Australia, New Zealand

Tractors in Regions 1, 2 and 3 are equipped with ECE (ECONOMIC COMMISSION FOR EUROPE) electrical systems.

Tractors in Region 4 are equipped with SAE (SOCIETY OF AUTOMOTIVE ENGINEERS) electrical systems.

→NOTE:

The main difference between ECE and SAE electrical systems is the turn-signal light. Tractors with SAE electrics have the turn-signal lights mounted in the cab roof. The turn-signal lights operate in different ways. With SAE electrics, the turn signal flashes on the side selected, while the light on the opposite side comes on but does not flash. With ECE electrics, all that happens is that the turn signal flashes on the side selected.

There is one more difference concerning the lighting system. Tractors with ECE electrics have parking lights while those with SAE electrics do not.
