Late fall befor I parked my 72 skylark for winter, A couple of times the Gen light would stay on ,with ignition switch off. I looked in my 72 service manual ,and it said I had A positive diode shorted,locate and replace.It was saying power goes from gen light to voltage regulator,and to alternator. I was wondering if my voltage regulator may be going bad,wanted to see what y'all thought .
From what Larry posted ,that's saying maybe the alternator. Larry I didn't see that page in my book,I just got mine the other day. When it first happened I thought maybe ignition switch . I hate A electrical problem, can be mean to figure out.
It's in there. Look in the Generating System chapter. Follow the diagnosing charts or instructions. That's why you bought the book.
They are still infinitely easier to diagnose than modern cars. Old cars are very simple electronically compared to late model cars.
Yes ,they are. Larry I have read the chapter in my shop manual ,two times that you said to look. I'm starting to understand the generating system A lot better .The book really brakes it down very good.
