Anyone know if 120v wiring TO slide out spaces travels in roof space or under the slide? I’ve isolated a short problem in a Montana 3400RL (that trips the kitchen GFI) to the kitchen leg that runs to the DR/LR slide space. Only operates the ceiling light, wall light and two outlets in series. The ceiling light is about 6” from the interior side of the slide ceiling. Thoughts? Trying to understand IF I can access that romex and what the fix or new run should look like if I choose to fix.

Under the floor to the slide out. Look under and you should see a wire bundle.

Under the slide on the frame will be junction box look in it my bet is a burned wire nut

Almost certainly under the corroplast and then an extendable loop under the slide. Extend the slide and get underneath and look at the bottom. Usually there will be a loop of wire suspended by springs, so that it can extend/retract while keeping the wires tucked up. Good chance you will find your fault there too, since that is the least protected area. Maybe where the wires pass through the frame. That's a likely pinch or scrape area.

My old Komfort had a heavy coil cord that ran on a guide rod from under the belly covering to the outer wall. I guess that's now too expensive, so they just put a bunch of slack in a straight wire bundle and hope it doesn't tangle.Lyle

Those connectors often used for slides can be a source of problems. I pulled the plug on a trailer that was smoking from that junk.

The slides are powered under the slide and are attached to the supporting swing arms.

I added a 20A circuit to my kitchen with 12/3 "SO" cord and followed other wiring.

Thanks for the direction. I looked under there before but didn't see any cream colored romex matching what's inside! Just some 12v wiring and a black round rubber hose looking thing. But I think the black is the 120v wiring?? Looks like a pinch in the wiring exposing a hot wire.

So now, anything in particular to pay attention to for the splice, since it runs outside? Basic pinch connectors ok? Do I need to tape and isolate it back up like it is in the rubber hose?
