I have purchase a capacitor but have not tried to use it yet. In the meantime I have a question. I have unplugged and removed the controller and been studying it, trying to follow the sequence of events that should take place. My understanding is that when the Main Switch is flipped on, the Main Contacts close, causing current to flow through the run windings, and the Starting Armature Shunt Coil. When I flipped the main switch between on and off there is some movement of the contacts but they never touch. Is this due to the fact that there is no power to the controller or is some other factor at play here? Thanks. Seems there is some other factor at play. The main contacts should close and open with the switch, regardless of power state. That function is 100% mechanical. The functionality of the contacts depends on the bellows having pressure. If the bellows sensing tube is broken, there won't be any pressure to actuate the contacts. If that's the case, the bellows tube can be replaced and charged with isobutane.
Another thing I see happen often is the pivot points of the control linkages get stiff, and a little drop of oil here and there will solve the problem.

Being from the Land Of Oz I should have known the importance of keeping the joints well oiled. The points work just fine now. Thanks for the suggestion.
