Lamp - Cutting Edge Flood
Normally closed switch that will open with an increase of a specific condition. No circle indicates that the wire cannot be disconnected from the component. This indicates that the component has a wire connected to it that is connected to ground.
This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine. 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.
621G Wheel Tractor-Scraper Electrical System
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.
T
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.
ALP 1-UP (Machine) ANG1-UP (Scraper)
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.
Harness And Wire Symbols * Harness identification letter(s) and a serializing code. The "C" stands for connector and the number indicates which connector in the harness.
Harness identification code This example indicates wire 135 in harness "AG".
Machine locations are repeated for components located close together. F = Located around pilot manifold. Tr = Tractor G = Located under platform. Sc = Scraper I = Located on Implement Valve. A = Located inside of cab. J = Located around Top of XMSN. B = Located inside of right console. K = Located around Top of Scraper XMSN. C = Located inside of left console. L= Located in Cab Headliner. D = Located around relay panel. M =Located on Tractor Engine. E = Located around hydraulic oil tank.
