[Bulldog]

Those of you have this rig which switch turns on the four 12v lights in the center of the living room. I have tried having all switches I can see turned on then turned each of the four light switches on and off. I pulled each bulb out and the filaments appeared to be all good. The PO said they hadn’t worked for the four years he had it. He didn’t attempt to work on them. All the fuses in the breaker box are good. Seems strange all four of them don’t work. Any info would be appreciated. Plan going on our first trip in this rig on Saturday.
