HARNESS AND WIRE SYMBOLS Wire, Cable, or Harness Assembly Identification: Includes Harness Identification Letters and Harness Connector Serialization Codes (see sample).

Fuse: A component in an electrical circuit that will open the circuit if too much current flows through it. Switch (Normally Open): A switch that will close at a specified point (temp, press, etc.). The circle indicates that the component has screw terminals and a wire can be disconnected from it. Switch (Normally Closed): A switch that will open at a specified specified point (temp, press, etc.). No circle indicates that the wire cannot be disconnected from the component.

Ground (Wired): This indicates that the component is connected to a grounded wire. The grounded wire is fastened to the machine.

Receptacle Pin or Socket Number

Plug

Ground (Case): This indicates that the component component does not have a wire connected to ground. It is grounded by being fastened to the machine.

Harness Identification Letter(s): (A, B, C, AA, AB, AC, ...) Harness Connector Serialization Code: The Code: The "C" stands for "Connector" and the number indicates which connector connector in the harness (C1, C2, C3, ...)

Reed Switch: A Switch: A switch whose contacts are controlled 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.

T

Sender: A component that is used with a temperature temperature or pressure pressure gauge. The sender measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure. Relay (Magnetic Switch): A relay is an electrical electrical component component that is activated activated by electricity. electricity. It has a coil that makes an electromagnet when current current flows through it. The electromagnet can open or close the switch part of the relay. Solenoid: A solenoid is an electrical component component that is activated activated by electricity. electricity. It has a coil that makes an electromagnet when current flows flows through it. The electromagnet can open or close close a valve or move a piece of metal that can do work. Magnetic Latch Solenoid: An electrical component component that is activated activated by electricity electricity and held latched latched 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.
