I checked the dash for a warning light, engine running and in drive, with the bay door open with shore power on and shore power off. No warning light. There is nothing in that bay except for the transfer switch and the plugs for shore power and cable TV and no bay light. I even checked the high outside light above the water bay.
I guess I'll have to contact Thor and see if they can answer what the switch is for.
