All ActivityMost RecentMost LikesSolutionsinverter/charger issuesHave a 2007 Holiday Rambler Ambassador. Remote for the inverter/charger shows a fault, ie overcharge on batteries & high tempature. Batteries are new and fully charged. I have power to the slides, but nothing else works. The battery switch to turn on 12 volt power will not stay on. Hooking up to shore power makes no difference. Will a bad inverter/charger keep both the house electrical systems from working? Also, the generator will not start or come on line. Need an idea of where to start, all this happened with no warning.Electrical issuesI have a 2007 Holiday Rambler Ambassador and am having issues with both the 12 volt DC and 115 Volt AC circuits. The unit was in the shop for several months getting a new floor and having some body work done. When got it back the chassis electrics worked but, nothing else. The inverter charger has a fault light on saying check battery temp & batteries (house) overcharged. All house and chassis batteries are new and all are fully charged. The 12 volt battery switch will not stay engaged. Hooking up to shore power makes no difference and the generator will not start. All fuses and circuit breakers are fine. If, the inverter charger is bad will it keep the entire chassis system from operating? Is their anyway to bypass it to get the lights and generator to work?Trying to get an idea on where to start. Thanks for any suggestions12 volt power switchHave a 2007 holiday rambler ambassador. Has been parked for a while, having a new floor installed. When I picked it up the 12 volt activation switch doesn't work. When you press the rocker switch next to the door nothing happens. I have new house batteries and it starts up fine, just no lights , water pump, no generator start. Maybe bad relay or solinoid?
