    Replaced my alternator today (07 Classic 2500) and after the new one was in, started the truck and got a message on the DIC that "Battery Not Charging" Meter'd everything, it all checks out fine??? Ever happen to anyone?

    Update: Swapped Stock Unit Back in, No warning light. Brought the NAPA Re-man back to them, will further research in the near future.

    Thats why I wont buy napa starters alternators or fuel pumps or most other electrical components. There either not to good, or I have really bad luck.Advance has a line of brand new starters and alternators tha have been excelent even for china products.

    Definitely had the right one, I've read a few other sites a couple people had trouble with re-man units doing the same thing, must be something to do with the regulator not communication to the PCM

    I'm thinking your correct. Just try another one. Were you looking for a bigger alt.? Are u having charging issues?
