From the terminal block, it looks like an old aircraft starter-generator. They were made by several companies to maybe the same spec. I've seen a number of conversions using them, mostly from 20-30 years ago. You'd likely have better luck searching for the Jack & Heintz version. There's been a few related discussions on this board. They're pretty rugged.Does anyone know what a GE 2CM77 motor looks like? I believe that is what I have in this car I picked up. I tried googling lots of different ways but cannot find a picture of one and there are no numbers on this motor to help identify it. There is 4Awg on the E-, C+, with a small 10Awg on A+. It runs just fine this way but if there is another way to do it, I'm interested.
