What happens to a 110V single phase capacitor start motor when connected across 220V? Does the 125V start capacitor burn out before the motor windings do? We noticed that the motor windings were cold and test between windings gave us 2, 5 & 6 ohms. The motor only ran for 1 second before going off yet the windings didn't show any signs of overheating but the motor now won't start. Could it have burnt out the start capacitor or is the motor damaged? Any help will be appreciated
