Greetings to all and hope everyone had a great summer and is ready to welcome the change of seasons! Here is my scenario. Last winter, I took my 2009 Flagstaff 207D and gave it an electrical enema. I removed the existing 30A distribution panel and installed a 50A panel, along with more outlets. Every outlet, the A/C, the fridge, and the 12V power converter, are now all on their own dedicated breakers (and I have two open for possible future outlets, if desired). Each new outlet was run with 12/2 Romex. Everything 120V works as expected and I have yet to overload a circuit...but I haven't really tried. Here is what I cannot figure out. Everything works, as I said, except for the 12V power when the camper is not plugged in to shore power. Everything is wired correctly. I have checked and double-checked. The 12V power converter even says the battery charging and maintenance is working properly, and I know the battery has charge because the power lift always works. So...what could I have possibly done wrong? Any thoughts?
