CIRCUIT TESTING General Information

!

WARNING: Never operate the engine in a closed building. Proper ventilation is required under all circumstances.

!

WARNING: Before carrying out any servicing, repairs or troubleshooting procedures on tractors equipped with speed sequencer make sure the range transmission selector levers are in NEUTRAL and the range selector rods are disconnected. Failure to do this may result in serious injury.

IMPORTANT: MAKE SURE the transmission range levers are in NEUTRAL and the speed sequencer selector rods are disconnected, refer to Section 10004 for the correct procedure. IMPORTANT: All electrical checks must be made with the tractor parked on hard level ground with the parking brake engaged and the engine OFF unless otherwise stated. IMPORTANT: Put blocks in front of and behind the rear wheels. IMPORTANT: The batter y must be at full charge and all connections must be clean and tight before testing. Only use a HIGH IMPEDANCE multimeter for the tests. Do not use a test lamp or damage to the switches may occur. IMPORTANT: Use MC2656 test probe kit when making electrical checks at connectors to avoid the risk of shorting between the connector pins or terminals. NOTE: When measuring resistance values, always measure the resistance of the multimeter leads before testing components. Subtract the resistance of the multimeter leads from the component resistance to obtain a true resistance value. NOTE: When testing diodes and diode modules use the multimeter diode test function. NOTE: All components, wires and connectors disconnected during any electrical checks must be connected when the checks are completed.

SECTION 4001

CIRCUIT GENERAL INFORMATION Starter Circuit The starter solenoid will only operate when the Forward/Neutral/Reverse lever is in the neutral position. With the key switch in the START position, battery power at terminal 1 flows to terminal 2 then to the Forward/ Neutral/Reverse switch at terminal 4. With the Forward/Neutral/Reverse switch in the neutral position, power flows through the switch from terminal 4 and out of terminal 5 to the starter relay at terminal 86. Power flows through the relay winding to terminal 85 and to chassis ground at G6 energizing the relay. With the starter relay energised, battery power at terminal 30 is connected to terminal 87 and flows to the starter solenoid at terminal S to ground internally through the starter motor, energising the solenoid. With the starter solenoid energized, battery power flows from the battery to the starter motor (through an optional jumper stud or battery master disconnect switch) and to ground internally through the motor, operating the motor. NOTE: For tractors equipped with master disconnect switches, when the switch is in the OFF position all battery power is disconnected to the tractor except for power for the instrument cluster clock, interior light, radio and independent front suspension axle controller (if equipped).

Fuel Shut Off and Auto Advance Circuit General Information Battery power is available at the key switch terminal 1. When the key switch is in the ON position power flows from the key switch at terminal 5 through fuse 38 to the fuel shut off solenoid terminal A. Power then flows through the solenoid to terminal B and to ground at G6 energizing the solenoid. Power also flows from terminal 5 of the key switch through fuse 38 to the auto fuel advance temperature switch. When the engine coolant temperature is approximately 50°C (122°F) power will flow through the switch t o the auto fuel advance solenoid which will melt the wax inside the coil gradually reducing excess fuel delivery to normal operation after approximately 3 minutes. If the engine coolant temperature is below 40°C pow er will not flow through the switch to the auto fuel advance unit, this will allow excess fuel delivery.

Cold Start Circuits American specification tractors are equipped with either Thermostart or Ether Start, European specification tractors are equipped with Thermostart only. With the key switch in the ON or START position battery power at terminal 1 is connected to terminal 5 and flows through fuse 37 to the cold start switch terminal 1. When the switch held ON power flows through the switch to terminal 5 and to the ether start solenoid or the thermostart unit.

Ether Start When the switch is held ON power flows from terminal 1 of the switch to the ether start solenoid terminal A. Power then flows through the solenoid to terminal B then to ground at G7 energising the solenoid. This allows a small amount of ether fluid to enter the engine air intake.

Thermostart When the switch is held ON power flows from terminal 1 of the switch through the Thermostart Unit to ground operating the thermostart heater element. The element will increase the temperature of the air flowing into the engine. continued.... SM 8-11141

Issued 01-2005


SECTION 4001

Accessory Power Relay With the key switch in the ON or ACCESSORY position battery power at terminal 1 of the key switch flows through the switch to terminal 6. Power then flows to the accessory power relay terminal 1 (86), through the relay windings to terminal 2 (85) and to ground at G1 energising the relay.

Cab Power Relay With the key switch in the ON position, battery power at terminal 1 of the key switch flows through the switch to terminal 3. Power then flows to the cab power relay terminal 86, through the relay windings to terminal 85 and then to the accessory power relay terminal 3 (30). With the accessory power relay energized (see above) power flows through the accessory power relay to terminal 5 (87) and to ground at G1 energising the cab power relay. With the cab power relay energised battery power at terminal 30 flows through the relay to terminal 87 and is available at the switched power stud and supplies most fuses. When the key switch is moved to the START position the accessory relay is deenergized. This will prevent power flow to ground from the cab power relay, which becomes deenergized.

CIRCUIT TESTING NOTE: The battery must be at full charge and all connections must be clean and tight before testing. Only use a HIGH IMPEDANCE multimeter for the tests. Do not use a test lamp or damage to the switches may occur.

Starter Solenoid Circuit Test IMPORTANT: Before carrying out the following tests, refer to “CIRCUIT TESTING General Information” on page 5. IMPORTANT: Turn the key to the OFF position, engage the park brake and put blocks in front of and behind the rear wheels. Disconnect the fuel shut off solenoid from the harness. NOTE: For tractors equipped with master disconnect switches, make sure the master disconnect switch is in the ON position.

Check Point

Reading

Possible Cause of Bad Reading

Check 1: Between terminal B of the starter solenoid to ground.

12 Volts

Check the battery cable between the battery positive terminal and the starter solenoid terminal B. Also check the master disconnect switch if equipped.

IMPORTANT: Make sure the range lever is in NEUTRAL and the Forward/Neutral/Reverse lever is in the NEUTRAL position. NOTE: Hold the key to the START position. Check 2: Starter solenoid terminal for wire 625 White to ground.
