i went to change my alternator today with a used one i got, and i got everything unbolted and what not, but i couldnt get the old one out of the engine bay. i tried taking off part of the brake master cylinder, but i stripped one of the bolts in the process. so i cleaned up the old alternator and put it back on. and now it runs fine. wtf? BEFORE, the battery light would come on when i came to a stop and it would whine. i drove it around for a while today and seemed fine. wtf? anybody got any comments? ideas?
