Symbols and Definitions
Fuse (5 Amps)

T
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 ha
screw terminals and a wire can be disconnected from it.
Switch (Normally Closed): A switch that will open at a 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.
Ground (Case): This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to th
machine.
Reed Switch : A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch;
opens the contacts of a normally closed reed switch.
Sender: A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. It
resistance changes to give an indication to the gauge of the temperature or pressure.
Relay (Magnetic Switch): A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagne
when current flows through it. The electromagnet can open or close the switch part of the relay.
Solenoid: A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when curren
flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work.
Magnetic Latch Solenoid: A magnetic latch solenoid is an electrical component that is activated by electricity and held latched by
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.
Harness id entification code:
This example indicates wire group 325,
wire 135 in harness "AG".
L-C123E-5179
Wire, Cable, or Harness Assembly Identification:
Includes Harness Identification Letters and Harness
Connector Serialization Codes (see sample).Harness Connector Serialization Code: The "C" stands
"Connector" and the number indicates which connector in
harness (C1, C2, C3, ...).
