Picked up a dead 400V HVAC flu motor at a flea market. At 120V no current would flow so I took took it apart and found an open very fine copper wire. Soldered open wire, motor now passes current, and will move the shaft a fraction then quit,, at 120v. Also, tried manually spinning motor to give it jump start,, no go. I do not need the motor since I only have 120 and 230V. It has value and would like to sell,, but want to make sure it is working properly. Thought about connecting 220V but motor's power input only has 2 wires so I do not know how to hook up 220V(120V,, simple blue and red). The capacitor tests good. Attached is wiring diagram. Any advice how to test/wire motor for proper function greatly appreciated.
