saflyer Posted February 4, 2022 Share Posted February 4, 2022 My ‘05 HR Ambassador is stored in a building on my property. I have it hooked up to 50a shorepower but disconnected the lithium batteries. I guess the inverter/charger still powers the 12v house items because, without thinking about it, I ran a slide out. Is there any potential harm in doing this? Ed Link to comment Share on other sites More sharing options...

The batteries might act much as an accumulator in a hydraulic system. They’d absorb pulses and surges or drops of pressure (voltage). I turned the shore power off and tried the slides. They didn’t move proving they are on the house and not chassis system. However, now that I have turned the shore power back on I get a fault light on the EMS panel. I believe this is preventing the heat pumps from coming on, or anything else AC. I really need heat tonight as it’s supposed to get down to possibly as low as 3°F. Any suggestions of how to clear the fault without reinstalling the house batteries? Ed Link to comment Share on other sites More sharing options...
Rick A Posted February 5, 2022 Share Posted February 5, 2022 My next line of attack would be to reduce power usage to a minimum then run the generator and hope that resets the system. Link to comment Share on other sites More sharing options...
