Yes, at first I thought it was a diode in the alternator gone bad. I had the alternator checked out by a good local shop and they said that everything was fine.

I'll check the corrosion / proper ground stuff first. I will let you know what I ultimately find is the culprit.


When I apply the brakes the headlights and dash board lights dim slightly. When I release the brakes the headlights and dash lights brighten up again. Has anyone experienced this and what was the fix? I'm thinking it's a voltage regulator internal problem. With the engine running and using a volt meter the voltage drops to about 12.5 volts when the headlights turn on and then goes right back up to 14.5 volts.

Help!!
