any suggestions for alternator whine?


Recommended Posts

Only got 1 battery in the back, none in front. I did get somewhere today. I changed grounding points on engine and alternator to frame grounds. Its about 80% gone now. Its odd cause those grounds have been there for over a year and I never had a problem before. Maybe when I moved batt to the back, the engine grounds weren't adequate...

I also ran a new 18g ground from battery in trunk to headunit but that didn't do anything. I was reading that article somebody posted from crutchfield about ground loops
