I have a jayco class c and was stopped at rest area and started generator which was running and started the air then turned on microwave to heat food, it then knocked out power like it blew a fuse, I have checked breakers under bed all ok, what's wrong did it blow a fuse? if so where is the fuse box? is it under hood or in the camper? I have found fuse box under hood all look ok, the air works ok when plugged in to 110, but not with generator. thank you ahead of time for input. dabrown
