You might also check the back side of the switch to see if there are multiple connections at that point.
I've not checked those connections on mine, but I'd guess that the wire that feeds the ceiling also runs across to the overhead lights at the island. Really strange that the problem would appear overnight.
According to the wiring guide the wires will be green & white 14 ga and should have a number stamped on them (probably 3 - maybe 4) for the zone in the trailer.
Good luck - let us know what you find!
It might well have been the heat! Even though it is much
cooler today than it has been.
I did drag the step ladder in and checked all the high connections I could find and did not see anything obvious. So I pulled out the switch panel to check the back side of the switch. Let me tell you what! That is a complete, total RAT'S NEST
back in there. I started trying to trace the wires from that switch through the mess which required getting my hand in there and moving wires around and all of a sudden all the lights started working.
There is group of 7 wires that come together in a big crimp cap that feeds all the light runs off that switch, well two actually, one hot and the other ground. I have no idea which it was and I could not feel or see anything loose but they are working again. It is amazing how dark it seemed in here without those on as we are keeping the window shades mostly closed due to the heat.
Thanks for getting me thinking along the right path to solve it. I appreciate it, as I have gotten older I sometimes need someone to give me a direction.
