More complex than I hoped - a safety switch - an overload protector a start capacitor power in and power to the motor...
This link might help - a Sears Craftsman wiring diagram...
Your first challenge is to get the safety switch operating - connect up the capacitor and the motor only when you're content with the safety switch - it should make and hold itself on until the power is interrupted and then drop out. You test it by pulling the plug.
