Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

There isn't any protection against reversed polarity. Individual circuits are protected by fuses and fuses will often blow when polarity is reversed. The first thing that should be done is check fuses. Outside of blown fuses, any electrical component can be instantly damaged if polarity is reversed. There is a good chance that one or more modules will need to be replaced.

My goal is to give you the best experience possible! I hope I have earned a 5 star rating! Please remember to rate my service by selecting the 5 stars at the top of the screen before you leave today. If you need more assistance, please use the reply box and let me know.
