2002 Coachmen Leprechaun Cab Clearance Light OUT??

No, actually one of the side markers at the belt line was also dead, and turned out to have the same issue with +12v on both conductors... That is where I was able to find the wiring behind the kitchen cabinets and tap into the ground and run a new ground leg, which makes all of the lights work again. There must be either a separate ground circuit for those particular lights, or a break in the ground wire somewhere between them and the remaining clearance lights, as all of the others worked just fine??
