2013 Cyclone 4100HD. We have 4 golf cart batteries. We don’t run on generator often so I kept forgetting to post this issue. First clue; Lippert hydraulic jack panel reports low voltage when operating the jacks. Second clue; circuit breakers blow for no apparent reason for things that work fine on shore power. Third clue; batteries are dead. Fourth clue; batteries only charge when connected to shore power. Last clue; Norcold fridge reports “low DC” when mode set to AC auto and generator is running. What the heck is going on? Family emergency finds us parked at a Walmart, running generator in -10 weather and if the generator stops, we aren’t going to be able to start it back up again with no batteries. Mind you this is temporary, we are moving to shore power at my brothers house (50 amp), before we wear out our welcome at Walmart, but the threat of losing power in this weather is stressful on top of our family emergency. Any ideas where our trouble lies?
