Check your Shore Power Plug & RV wire connections regularly!

An OP here lost all power in his Class C. I looked at the wiring diagrams and called him, asking he find the splice box where the hard-wired flexible shore tie cable met the solid interior wiring of the coach. He did, and the connections were burnt out. Re-connected and all was well. Called the RV tech he'd scheduled to come look at it and tech asked if he'd been using portable electric heaters. OP said Yes and RV tech said failure at that splice is very common and heaters are the common cause.
