Re: Odd Brake Light Issue
Yup, it's a grounding issue. Power to the socket at 12v on 2 connectors and ground.
What changes is the continuity to ground. Basically it shuts down.
I unplug the rear brake light socket from the connector I then depress the brake pedal I then check continuity between the ground wire of the right brake light wiring and the body of the car: It's 2.3 ohms.
I then plug the socket back into the connector and the bulb comes on for 3-4 seconds and then fades out. Fades, not short or shut off. Dims itself out.
I then re-check ground continuity btwn the plug and ground and it's dived to 65k ohms.
So, for shits and grins I thought I'd just attach the socket ground lead to the body at the back of the car...nothing. still doesn't work.
Also, I swapped the #1 number relay that controls the left brake light (works) with the number 4 (right break light which doesn't) and there is no change.
What ever is responsible for grounding that socket or insuring amps isn’t working. Me thinks.
Thanks a ton for the wiring diagram.
