Our 12 volt was totally down one morning when we only ran the propane furnace and the heating water tank blankets. We were connected to shore power the whole time. the TV, the microwave and the outlets all worked fine. But..... the charge was totally gone on the 12 volts, the lights didn't work the led readouts and the furnace wouldn't work.
Electric was coming from the plug into the cord to the RV.
We turned on the generator and within 20 minutes we had a 1/3rd of a charge and after an hour full charge.
We just took it into get checked, the fuses and breakers are all ok, even the converter breaker.
So odd, but the guy there thinks it is the solenoid by the battery and is checking it. Has anyone else had a problem like this? Our RV home is a 2011 Jayco Greyhawk 26 SD.
