I have the lippert level up system and when I checked it this morning it said "low voltage" my questions are since I am hooked up to shore power at the rv park, how can their be a drain on the batteri...
My converter has two fuses on it that protect it against things like someone accidentally reversing battery cables. When out batteries were dying while hooked up to shore power, I pulled them and found them blown, keeping the converter from charging them, thereby running them down as the lights and heat still were running off the batteries.
