Time Delay Relay/Ignition Switch Lamp

TIME DELAY RELAY/IGNITION SWITCH LAMP
The time delay relay is used to allow a time-ON function for the ignition switch lamp. Power for the relay is received on the M1 circuit from the 10 amp fuse located in the Power Distribution Center (PDC).

When a door is opened, or the headlamp switch is moved to the dome lamp position, a ground path is provided for the relay on the M2 circuit. This energizes the relay, closing the contacts. When the relay contacts are closed, power is provided through the relay to the M50 circuit.

The M50 circuit supplies current to the ignition switch lamp in the steering column. Ground for the lamp is provided on the Z3 circuit. This circuit splices with the glove box lamp, the ash receiver lamp, and the PRNDL lamp. The Z3 circuit terminates at the instrument panel left center support.
