A friend of mine has an RV which requires 240volts to run his Air Conditioner. This plug has indicator lights on it which tell whether or not the circuit is good. When he has it plugged into a dedicated circuit for his RV, the lights show "Bad Polarity". When he plugs into an RV Park everything works fine. I have checked the two legs and get 120v on both of them, and 240volts between them. What am I missing?
