We've owned 3 GMC's. All 3 GMC's were 78 Coachman built Royales. Coachman installed ground wires to all appliances, and lights. All the ground wires went back to a ground bus bar that was next to the 12V fuse block. I see no ground bus bar. Both the 12V buzz box wires weren't attached to anything. So I assume that the buzz box neg. wire is to be attached to the coach body. I want to get the modern solid state 120V to 12V convertor installed to test the 12V systems. I'm painting all the backsides of everything that goes back in. ( For future odder, and moisture absorption control. ) This electrical work will give the items that I painted today. More time to dry before the installation. Bob Dunahugh The Building of a GMC.
