Anyone know how I can test it to see if it is that, or something that would make the alternator screech like that. Any help is appreciated.
If you find that the pulley/fan isn't rubbing, it could be a bad brush internally. Another thing to consider: If it's really loud, you'll at the very least have to remove it to fix the problem, whatever it may be. Consider how much your time is worth. Using a bad alternator as a core in exchange for a rebuilt alternator from Discount shouldn't be all that expensive. Less than $100. About $80 after core. It's a pain in the ass to change brushes, IMO. Why bother when you can have a clean serviceable part ready to go right in
