When I bought my 18 month old RV, the previous owner had stored it unplugged, without doing any battery maintenance since new. I was able to hold the converter unit in my hands and could get the fan to start/stop just by tilting the unit different ways (again, no generator and no shore power present). When setting up the trailer, I unknowingly pulled the emergency brake switch cable, thus the 12v electric brakes on all 4 wheels were constantly activated.. the converter / batteries were always trying to keep the power to them... once the pulled cable was discovered 4 days later and reset, the problem went away... Just an idea... Ted. A recreational vehicle (RV) uses a power converter to transform 120-volt alternating current (AC) from the shore power cord or a running generator to 12-volt direct current (DC). This situation only occurs when you are connected to shore power. That is a simple duty that when not done right cause expensive damage. It was just the proverbial straw, on top of whatever else was going on that wasn't obvious (like the turned-off radio, the charging phone, etc. To learn more about this problem just continue to read our article.
