My favorite old guy mechanic, he's 80, checked the generator that I bought from him with the wire brush on a bench grinder and a screw driver. He spun the pulley with the grinder, and used the screw driver to arc from the out put terminal to the case. He is really a safety oriented guy. If you can find an old service manual from a sixties chevy, they have a diagram on how to hook up the wire to turn the gen into an electric motor, if it spins it is fine. This is the same principal that a cub cadet starter/gen combo uses. Jay
