About electrical gremlins

2016 Force HD 36fks: Overhead lights in dinette, sofa slide quit working. The bathroom, bed head end overhead lights also quit, not at same time. Have the electrical schematics of the DX3 which I assume are close to the Force. Schematics are not much help as no locations of where a lot of the terminations, cluster connections are located.

Have done this:
1. Continuity at switches, no power, individual lights had been working, no flickering previously.
2. No fuses found blown, or breakers, rest of lights, electrical work
3. Checked cleaned grounds that I could find in back of rig.
4. Cleaned ceiling electrical plug that connects outside by propane tank in back of rig, which did have some water intrusion in plug, no change, and I don't think these problem light circuits connect through here anyway.

1. Have found one fuse in bedroom marked compartment lights and one relay in front electrical cargo compartment marked compartment lights. Both test ok.
Is this all of the fuses/breakers for lights, clearly there are several coach light circuits. Anywhere else to look for light fuses?

2. Is there a termination block somewhere for coach light wiring to tie too?

Thanks for any suggestions

While my 37TS is not the same as yours, I saved this from a post when someone was having Porch Light power issues. The overhead lights are all run from a ceiling harness. It might be at the connectors to this harness where you have an issue. Since all the lights you describe seem to carry through the roof harness, fingers crossed it gives you an idea of something to look for. See attached (2 pages). Hope it gets you some traction in the right direction. Good luck!

Great ! This electrical schematic is much better than the one I had found. Appreciate the help!
