How to test an AC motor ?

Hello all there is a lot about this subject out there but I could not find anything helpful so here it goes I was given this tool to see if I could fix it and keep it , is a Milwaukee band saw 6236 deep cut and I have limited knowledge about ac motors so I took it apart and the windings check out good as well as the armature I have to put it in a growler to finish test so I wanted to eliminate the on and off switch for a moment and test it direct this motor is a single phase with only 2 winding and has 2 speed I think , there are 4 cables coming from the windings and 2 for the carbons and it does not have a capacitor can anyone tell me how to connect the wires so I can test the motor thank you in advance

Answer:

If you want to bypass the switch, then put another one in line. Go ahead and connect the wire going into and out of the switch together. Just use a twist-lock for testing purposes. Then get a normal 79 cent household light switch and use that between the plug and the motor. Use some electrical tape to cover the screws so you don't shock yourself. You might also tie the motor to the workbench so the start-up torque doesn't cause the thing to jump off the bench.
Put everything back the way it was, and use the ON/OFF switch to test it.
