I did a search on this and came up with mixed problems and solutions. Ok, this started about 6 months ago, while driving around for a while then coming to a stop, the brake/charge light would come on and there was a buzzing coming from the fuse panel area. It was fine until recently when it started happening again. I changed out the alternator and everything was good until a few days ago, when driving with the a/c, defroster and lights on the charge light comes on very dim but when I take my foot off the accelerator pedal it goes off. It seems the fast I accelerate, the more it comes on. Could this alternator be bad also? I cleaned the grounds on the battery cables but didn't seem to help. I got the rebuilt alternator from pep boys, are these crappy?
