Well, I got home and plugged my EMS directly into the wall plug to test it and got the Reverse Polarity code as expected. I turned off the circuit breaker, removed the plug receptacle and reversed the wires. Voila! It works properly. This puppy has had reverse polarity since it was installed by a reputable electrical company! I’m glad that I hadn’t damaged any electronics in the RV. Thanks again for all of your help with, tool suggestions, pictures, etc. It made it easy for me to tackle this myself. Not bad for a somewhat mechanically inclined 66 year old woman! Most of you assumed that I was a man but at the end of the day, it doesn’t make any difference as we are all very capable of many things!??
