On my '84 944 N/A the alternator isn't charging the battery. I took it to autozone and it checked out as good. Disconnected the little blue wire from the blue/white wire connector under the dash and the battery dash light went off. All the grounds look good, where else should I look? Can the connection to the starter influence the alternator's charging ability? I hate car electronics.

Thanks for the help in advance!
