Hey Scotty I have a question I recently bought a rebuilt alternator from pep boys about 3-4 weeks maybe now. When I start the car I here like a humming noise around that area now. When I hit my lights or turn on my ac the noise stops for a few secs then comes back. Is the alternator messing up already?

those discount alternators are often poor . Remove the belt, and if the noise goes away, yea, they sold you a bum alternator
