charging / engine noise

6 years 6 months ago #1 by steveo
Got a massive noise going on.
thought it was an RCA issue. So the hole systems Rca's were replaced. No luck..
then we noticed when we uplugged the alt plug the noise went. so i had the regulator changed and alt tested by auto sparky. the alt and reg was good. but noise was still there.
so i unplugged charge sensor wire from the alt plug, and the little supercharger noise left. leaving a constant hum that dosnt change with revs. im thinking a ground loop. how ever as soon as i plug the charge sensor wire back into the plug and the supercharger was back aswell as the tone lol
Any Sudgestions?
