Yeah, the ground wire! tee hee

Seriously, I am wondering if these thin ground wires, having higher capacitance, are holding a charge and when the brake lights come on, the regulator does not compensate fully. Or, it could be a ground loop causing it. Hopefully I will get all of the pieces/parts and change them this week. If nothing else, I will have shiny ground wires.

hehe, not a waste of time though: your contacts are clean. I think a large part of the problem is the pi$$ant little ground wires being capacitavely charged and/or causing ground loops.

....he just shook his head [xx(]and said it is a ground problem and it would not show up on the computer print out from the tests so i drove the car back in to the shop he spend all of 2 minutes pulled the ground wire off of the body used a file to remove the paint then he put a yellow conductive paste on it to make sure no rust starts and rehooked up the cable ..... problem solved

Is this the ground wire from the negative terminal of the battery to the car body??

it was on the Ground wire from the Battery to the body

tangerinedream1845 do you know which ground they repaired?

what i was told was ... when you are running your lights , radio , fan and what ever else you might have going then you let up on the gas and hit the Brake it takes a second for the ground to catch up to the drain on the electical system of the car so when you give the ground a better contact it can compinsate more quickly for the draw on the power so you don't get the dimming lights
it made sence to me

Yes! Flaky contact = resistance = voltage drop = flaky ground = weird problems.

It's funny, I was thinking of polishing the paint off of that contact, but decided against it. I shall revisit that. I am glad somebody mentioned it.
