Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...

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 ...
