OK Mike, Here's what I did............
1. I checked the voltage with a meter at the battery with the car off. It was about 12.5v.
2. Then I started the car and it went to about 14.25v.
3. Then I started the car and removed the negative battery cable. The car didn't die. I let it run 5 min. or so.
Seems the alternator and voltage regulator are ok? The battery has a 6/2020 sticker on it so it IS 4 years old and it HAS had a problem where it keeps going dead according to the Seller I bought the car from. SO maybe we're talking about buying a battery here and seeing what happens? With the voltage going up so much while the car is running it makes me believe the alternator is working. How about you?
