Recently took delivery of 3760 Big Horn and on our first trip to our seasonal site we found the lo dc error message on the display screen of the polar max 2118. That Monday called the dealer and I completed some troubleshooting for them since we lived 4 hours away. Found that only one battery was installed, however, it was fully charged and the converter/charger was working properly. Also checked the voltage at the dc control box on the back of the fridge was only 11.8 volts. Dealer had me add a another group 27 battery wired in parallel and for that weekend all worked well.
The next weekend the error message was back intermittently, So I checked battery voltage 13.1v, checked the charger 13.6v and at the fridge control box 13.1 so it seems all the voltages are good. Has anyone else run across this problem and if so what was the fix? Thanx
