In the past trip, I started to experience electrical issues. When connected to my generator(Predator 3500 Super Quiet Inverter), the surge protector and the LED signal lights on the stock power plug have given multiple issue codes. When power is given to the camper with all breakers on, I get a “open negative” signal on my surge protector and a “reverse negative” on the signal LEDs on the power cord. When turning off breakers to isolate the issue, the issue goes away when the 12 volt battery charger breaker is off, the microwave breaker is off, and the GFCI outlet breaker is off. Unknown if it is connected to the issue but the domestic fridge/freezer has resorted to only operating through propane and will not operate electrically. No fuses are blown and it has always been used on level ground. These issues started less than a month after warranty ended and trying to not break the bank.
It sounds like the battery may have been installed wrong or possibly grounded on the wrong side. The ground wire may have come disconnected from the trailer chassis. Have you checked the trailer manual?
