I do not know how, but I lost all 12V in coach. I have 12v when the gen is running but if I turn off gen the 12V is off. I can not locate master switch - if any.
8 gauge black wire going from solenoid to control box. I try to "chase" that wire, but it is too much cover. I will run 6 gauge wire from battery to control box with fuse(15A) in line. That will temporary give to me 12V until I find the brake. Having "hard time" locate wiring diagram for my coach.
