I took the barracuda out for drive on satuday and when I got back, battery was cooking. I checked the alternator out put and battery voltage and the voltmeter was pegged at 15v. I pulled the alternator and dropped it off at a local shop. The guy who tested it said it was fine and that it has to be the Voltage regulator. He suggested the alternator will not cause an overcharge problem. I picked up another voltage regulator and reinstalled it with the old alternator. Still has 15+ volts at idle.
Was the auto electric shop guy wrong about the alternator? Can it cause a overcharge problem on it's own? What other possibilities?
Thanks
