Can't Find Battery Switch

My neighbour just bought at an auction on a deal he says he couldn't pass up, a 1990 Georgie Boy Cruisemaster 27 ft on a Ford chassis. No manuals of any kind came with it. None of the house 12 volt systems work so I am assuming the battery has been cut off. Both chassis and house batteries are in front of the radiator behind the grille. I see lots of wiring and the isolator but nothing that looks like a switch. There is an On/Off switch mounted on a wall just inside the entry door which has no function label, and activating it does nothing. Several switches on the dash are also without labels and we are somewhat hesitant to just start flipping them willy nilly. We need some help please and thanks.

Hi JesseJ1826,
1. Check the battery to ensure it is at 12.5 VDC or more. Strange things can happen to 12 VDC systems when the source battery poser is not sufficient.
2. Go to to down load the 1990 manual for the coach.
3. Page 12 of the manual has the location of the battery disconnect relays.
4. Page 40 has the coach battery disconnect and the circuits associated with it.
5. There are many pages with the details of the coach systems.
