Well, we fixed the problem. I finally got a space in the shop for the car so I wanted him to bring me an new alternator and a new voltage regulator, even if they had both been tested good a month before by a really good place. He took the alt and had it tested again at a different place and it tested good again. He bought another new alternator and installed it to check it and have it towed to the shop. Started the car and it’s now working perfectly. The alt shop said they could not test it at a high rpm load so that is where it was overcharging. Sometimes it’s just simple.
