Great advice! Thank you, for that and the links.... Okay, I just went outside and unplugged the 120v. The interior lights all came on! Plugged back in, and they all went out again! You are a certified genius! (That's me, solving a problem!) : ) I guess I need to buy at least two plug-in lights for times like these. Thanks! I've learned something useful today! On my way to the store!

WME, thank you for responding. Might you suggest where to start looking for that additional cb? The "click" sounded as though it were right here, inside, which is why I went to the only cb panel I've been able to locate, so far. Btw, none of the 12v accessories were on at the time it tripped, which is why I didn't discover the "lights out" issue until hours later. If it's the converter/main CB panel that has a problem (its the original 1983 OEM equipment) I surmise that simply replacing it is the only solution, right? There is no 'fixing' it? The thought just occurred to me that perhaps the battery isolator isn't working and the house battery could be in a low voltage condition? Would that cause an auto-shut down of all the 12v accy's on that circuit to avoid draining the house battery too low? I guess I better run to the store and buy a multimeter.

Good morning. I'm new, both at owning an RV and to this forum. I'm quickly learning that I don't know anything! I guess owning a motor home will do that to you. i just acquired a 1983 New Horizon 20 ft motor coach. I was sitting at the dinette yesterday afternoon when I heard a "pop", much like a circuit breaker tripping. I'm plugged in to shore power so I checked the panel and cycled all the cb's and everything appeared ok. However, last night, my fourth night in her, I discovered all the 12v lights, including the range hood fan/light, were out. The battery charge indicator shows way up in the green. I started up the engine, then checked all the exterior lights, which functioned normally, so the problem seems isolated to the 12v circuit in the house. This morning I found the fuse panel, hidden within the cb panel, and all of the fuses are good, so I'm stymied! Is there another fuse panel in the New Horizon coach? Yesterday was the first day I'd hooked up to shore power; could the electrical converter/charger/fuse and circuit breaker panel somehow be having a problem with the 110v, or is that a non-related issue? (I can see how this could possibly be a very complex electrical issue, due to the multiple interactive systems, but I would prefer to get my lights working first before tearing out all the wiring and starting from scratch!) Any suggestions or answers would certainly be greatly appreciated! Thank you. : )
