Today had time to get to work on the electrical problem on the host Cascade. Checkered the power coming to camper and it is good, checked batteries were almost totally dead. Ran a light test across the converter almost dead. The coveter is plugged into a regular 110 outlet in the basement, I unplugged it and plugged it directly to a separate extension cord. Everything in the camper came on and batteries are charging. I did checked the GFI plug and it appears fine. So stilll don't know where problem is, some where between the electrical panel and the plug? I need to add this is the second electrical issue I had. Before it was a dead short in the dinette slideout. Where do I go next?
