All ActivityMost RecentMost LikesSolutionsRe: Brand New Deep Cycle Batteries Keep Dying OvernightI have (2) Power Inverters installed but both turned off. Actually one of those inverters I removed completely last week but cables are still there - just taped up out of the way. Even though that line to the old (removed) inverter is still hot and live wire I can't imagine that drawing current as its no longer connected to anything.Re: Brand New Deep Cycle Batteries Keep Dying OvernightThe good news is that when I switch that main battery disconnect to OFF for the house power the reading on my volt meter is 0 so we know that works as it should. Its just when its turned on and everything else is off inside the motorhome something is draining down my batteries.Brand New Deep Cycle Batteries Keep Dying OvernightI just purchased (2) Brand New RV/Marine Batteries (Thinking I had bad Batteries) for my 1996 Winnebago Class C. It turns out there is a parasitic drain on the dual batteries of 2.35 amps when everything in the Motorhome is turned off. The strange thing is when I press the AUX Start Button by the steering wheel the drain on the house RV batteries drops down to 0.4 amps. I know there is a bridge / link between the engine battery and the house batteries but it appears that power is being drawn upfront and the drain is not caused from something running in the Motorhome side. Any ideas or suggestions?
