The function of a potential relay is simply to assist in starting the electric motor. Potential relays are commonly found on many smaller single-phase capacitor-start, capacitor-run motors in the ...

If the capacitor test is good, then with a standard ohmmeter, measure the resistance of the motor's windings. There should be a measurable resistance across both the run and start windings, with the ...

Illinois Capacitor's QPC Series AC Motor Run Capacitors are quicker to install and offer more durability and reliability.
