I have an alternator that has been checked out at the local Autozone, it passed...it's good. But I installed it in my car, A 1987 Firebird formula, and it doesn't charge. I disconnected the battery output and used a test light on the output, and nothing. There are 3 wires plugging into the alternator, I know the first wire is power, the second goes to an idiot light, where does the third wire go??
