contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.

¹ The CID is a diagnostic code that indicates which circuit is faulty.

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.

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.

MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is

activated by electricity and held 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.
