Your Bigfoot will have a little rectangular 30A breaker fastened with a couple of wood screws somewhere between the batteries and the disconnect switch. Follow the 8Ga. RED wire from the battery until you find it. I do not think it is a re-setable breaker....however, you say you have juice after the disconnect switch?..that 8Ga. Red wire goes from disconnect switch direct to the converter. On my 2002BF the camper battery wire and the truck charge wire both terminated on the same nut in the converter. Pull the front off your converter and have a look. Maybe the camper battery wire has pulled out of that terminal somehow?
