Reverse Polarity- Stereo not working

Hey all
I have a 71 Avion camper parked at an RV more or less year round. I have a car radio hooked up and shortly after I moved into the park, the stereo stopped working. My control panel read "Reverse Polarity". I know a little about the topic, but nothing else has been affected. No shocks, or appliances frying. Any clues?

  • Does the control panel indicate the 12v system is reversed, or the 120v system?
  • Measure the radio's input voltage with a voltmeter and see if the polarity is reversed.
  • Sorry, not sure if I'm being clear. There is no car in the situation. I mean to say a stereo you would find in a car. An in dash radio that's in the RV.
  • I'm not getting what a car radio and the stereo have to do with each other.
