Not sure if the issue I am having is the same, but it is close… When I am on S/P, my Xantrax PRO XM1000 is fine and everything is functioning properly. But when off of S/P, no Gen and the vehicle running or off, my Xantrex display has a ‘red’ fault light and then shows a E05 Code, ‘Over Load’. I have no DC Power at this time. No lights in camper and no Radio/Cameras system on dash. I have a 2018 Thor Four Winds 31W. I have checked all fuses on the Power Distribution Box/Converter and everything is good. I will start looking at the fuses around the battery box and under the hood. Any assistance would be greatly appreciated.
