Every light in my car pulses/flickers when my headlights are on (dash lights, headlights, taillights, interior lights, etc.). I have no idea why. I have a good battery and a good alternator (I had both of them tested). I pulled out my battery tray and sanded down/cleaned up the grounds. Someone told me that could be it. That still didn't fix the problem. It doesn't matter if The car sits at idle, or I rev it up. It still does it. Most of the time it pulses/flickers fast, but sometimes slow. I cant figure out what it is. A bad ground somewhere else? A short? I'm trying to get this problem fixed A.S.A.P, I don't really want to get pulled over and ticketed for something stupid like this. Cops are a**holes around here.
that could be your problem. try disconnecting your stereo system completely, both the power and bround wires. You may be drawing to many amps and your alternater may not be able to handle it. the other thing that i've seen before is that it's hooked up wrong?
Also check every ground possible on the car. disconnect and clean them good. I don't think its a short or you would have fuses blowing but anything is possible. if this does not work i would thake it to a professional.
TyTy: Get a power capacitor and try that for your stereo system.
And i do also have a blown mini 5 amp fuse. Slot number 4. I read it was the fuse for my plate lights. I would just look in my owners manual that is supposed to be in the glove box, but the PO took it and i didnt realize it until i got the car home. That is the only blown fuse though.
I had a friend who's vw did this. Turned out to be an aftermarket alarm with siren disconnected. Wasn't wired to kill the car and he had no remote to turn it off. It didn't even happen every time he drove the car. The alarm brain was hard to find and harder to trace and disconnect the wires for removal. good luck
