Almost total electrical failure
I'm certainly not an electrician. Have a 2010 Roo 23ss. Earlier this year, when I hooked up to a shore line at my home (using the big cord that came with the trailer), the GFI at the outlet would immediately trip. Some nice man from the Forest River forum advised me to turn off the breakers, plug into shore, then turn on the breakers one at a time. They all came on correctly until I got to the last one (water heater), then it tripped the GFI. No problem, everything except the water heater worked. I could live with that for the rest of the season. Recently I plugged into shore, then starting flipping on the breakers one at a time. Got to #5 (Converter) and I hear a soft hum for a couple of seconds then nothing (GFI in the garage is tripped). All the fuses are fine. I unhooked the battery. Tested it and it isn't fully charge, but it is has somewhat of a charge. When I unplug from shore and have the battery hooked up, the microwave lights up, the kitchen fan runs (very slowly) and the interior lights work (albeit very dim). When under shore power and the battery unhooked, even before I get to #5, the lights don't work and the fridge doesn't work. I'm at my wits end. My breakers are as follows:
Can anyone enlighten me on what might be wrong?
