I had the exact same problem. I just put in a cheap CPU I got off of ebay just for the hell of it, and sure enough, it worked! My next step is putting in an amp gauge so I know if the alternator ever gives out. I advise you do the same. Problem after that? Let me know. www.jaysonvonosinski.com

try another alt,the alt,s you buy are rebuilt,auto zone advance auto,dont trust them.go NAPA or a independent parts store,better parts.
