The DIC on my '04 Avalanche is telling me "Battery Not Charging" and both the battery and alternator checked ok. With engine off, I measure 12.4 v and running 14.7 so I know the alternator's working ok. Connecting an OBDII doesn't return any codes either. I suspect that the computer is hung up on error, but I don't know how to clear it
