I'm still running the stock alternator on my 85 and have noticed it runs right around 13 amps. When running the head lights, front & rear wipers and the rear defroster it drops to 11-12 amps. When the front two Piaa's come on it is right at 10-11amps.
So far the battery hasn't failed, but as I understand it you need at least 12amps to recharge the battery when running.
Question is do I need a bigger alternator. Looking at a 300 amp Mean Green but don't want to throw down $500 for that right now.
