      1st thing to check would be the caps. if the problem stays in the machine after changing the motor, and the chassis. next, follow the wiring, make sure there is no shorts.

          I agree with jim. Make sure the caps are wired correctly and BOTH working.

                Check your cent mech switch on your gearbox. It may be sticking or broken. To verify this, unplug the table motor plug and put it in the sweep motor, try to run the sweep with ta1. If it doesnt start, you know its the gearbox because you've verified the stator from the sweep is good on the table.

                    Batman, like Wang and Paul said, it's almost certain to be the cent. mech in the top of the motor stator.It's probably out of adjustemnt and/or sticking. While swapping the table and sweep motors, you may have inadvertantly given it some "percussive maintenance" and it might run ok for a while.

                    The sweep contactor will stay in (engaged) if the sweep is supposed to be running, whether or not the motor is plugged in.
