My Nova still has the stock replacement alternator with the external voltage regulator. The problem I have is that at idle in gear it just doesn’t put out enough juice. I have an electric fan, electric fuel pump, and when I also have all my lights on and the heater/fan goin I can actually hear my fuel pump slow down and of course the lights dim. Will a one wire alternator work any better? What about a smaller pulley for the alternator? I might even use an electric water pump in the future so I really should address this issue. Thanks, Scott!
