Hey Gip, not sure about the GK, but it could be a pre-wire for an optional bedroom ceiling fan. Seems to me someone else awhile back found one of these and that's the opinion what it might be.

Mine came wired with a phone jack in the convenience center terminating in the cabinet above the living room television, not a thoughtful spot, maybe they ran the wire & decided not to add the jacks.

Greg, first of all very thankful you caught this in time. You seem like the type who stay on top of unusual indications and didn’t just dismiss the symptoms. Good job!

On the unused phone cable, I remember reading a thread awhile back about the earlier coaches being wired for modem connections. Is it possible yours was in the final transition away from that? Seems like an odd place for a phone cable.

That is really unusual for a wire nut, but glad you caught it! Usually the screw on wire nuts are considered a good connection. I don't believe there actually is a requirement for low voltage to be in an enclosure, even on a residential home. There is greater concern Code-wise with low voltage being combined in enclosures with high voltage (110), as the low voltage wire can't carry the load if there was a short. It's pretty common to see low voltage stuff just hidden behind the wall typically. There are also no limitations on having low voltage splices or terminations inside the wall, unlike high voltage where you cannot terminate or splice in a hidden or inaccessible location.

I'm confident Jim is correct - the old style remote controls for the Fan-Tastic fan used an RJ11 wire (telephone wire), and power went to the fan directly, rather than the switch. The RJ11 cable only carried control voltage. Today Fan-Tastic went wireless on their remote controls.

This is so scary. I mostly worry when I leave and my poor pups are left behind in my rig. Do you think the burning was caused by the wires not stranded together well within the wirenut which led to high resistance? Could there be a problem elsewhere in the circuit? Everywhere in our coaches there are exposed 12 volt connections made with wirenuts.

Before taking this apart, I tool several photos and after holding the wires tightly and removing the cap, I could see that the wires were not all "inside" the cap. The person who put this particular cap on probably did not line the wires up properly before screwing on the cap and that cause a high resistance. High resistance leads to heat.

That would do it 🙁

How about a "Do It Yourself RV Kit"
