I was checking my tranny fluid today and noticed my alternator is making a whining sound, almost as if something is loose inside it. I still maintain 11.5-13v's but the noise definitley didn't sound normal. Is there any sort of eletronic cleaner I could spray in there or something to eliminate the screech? Or anything other suggestions?

BTW, It's only noticable when the hood is open - not so much when it's closed....


Thanks,
