Wire Gauge
Electrical Schematic Symbols And Definitions The circle indicates that the component has screw terminals and a wire can be disconnected from it.
Machine locations are repeated for components located close together. A Located in the cab. B Located in the lefthand console.
FUSE - A component in an electrical circuit that will open the circuit if too much current flows through it.
15
C Located in the righthand console.
1
D Located on or near relay panel.
REED SWITCH - A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.
No circle indicates that the wire cannot be disconnected from the component. 3 16 19 2

This indicates that the component has a wire connected to it that is connected to ground.
17
SENDER - A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure.
9
This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine.
RELAY (Magnetic Switch) - A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay.
24 11 25
23
CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the circuit if too much current flows through it. This does not destroy the circuit breaker and it can be reset to become part of the circuit again. SOLENOID - A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work.
The connectors shown in this chart are for harness connectors. Connectors that join a harness to a component are generally located at or near the component. See the Component Location Chart.
Machine Harness Connector And Component Locations
MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is activated by electricity and held latch by a permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them. It also has an internal switch that places the latch coil circuit open at the time the coil latches.
