Unidentifiable brown wire near electrical controller

I've been doing some work in the cabinetry where the electrical control system and the freshwater tank are located. The cable TV wiring is damaged somewhere and we have rotten video quality on CG cable.

I took the bedroom TV out, since we don't have TV in the bedroom at the S&B and can't see a need for it in the MH, so I decided to hijack the cable from the b/r TV outlet and hook the Campground Cable socket to it. Now, I have good quality video from the cable input.

While messing around in the cabinet, I spotted a brown wire in one harness that was broken off at one end. I can't find wherever it should be connected. There are no visible broken splices or "orphan" spade terminals down there.

Since I'm parked at home and plugged into the house 15A socket, there doesn't seem to be any "missing" function.

I'd like to get wiring diagrams for my rig and would appreciate info on where to find them. I'm a bit concerned about having a stray wire, with an exposed conductor, just waving around back there. I did tape it off so it can't short anything out.

In the "docked with shore power" config, there was no voltage on the wire.

Any ideas?

Yes. Could it be your right turn/stop indicator? Plug it in to your tow vehicle and press your brakes. Does it have voltage now?

"Brown wire" is pretty nondescript.
Is it coax?

Braided (twisted) copper?

What other color wires are in the bundle?

If you check around the site you will find out why there will never be a wiring diagram for your (or anyone else's) camper.

As to a "generic" diagram:

Frank,

My Georgetown is very similar to yours. What cabinet was the wire in? Sometime today, I'll go poking around mine and see if I can find anything.

The wire in question is about a 16-gauge stranded copper wire in a bundle that's just ahead of the electrical charging system controller, aft of the fresh-water pump. It's in the cabinet under the bedroom wardrobes which has the doors held closed by woodscrews in the top edge of the frame.

I don't pull a toad, so if it's a break in the harness to the toad umbilical, it's not an issue unless, at some future date, we do start to tow. I will go and check later today whether the turn signals on the MH are working correctly.

The strange thing about the wire is that it looks like it separated from either a spade teminal or an in-line bullet connector, and I can't spot an "orphan" matching wire anywhere close by.

Lou:

Surely the factory uses a wiring diagram when they build the coach, or do the installers just invent the wire harnesses as they go?

Frank,

The wiring harness in my Georgetown is in the same wardrobe area as yours.
The wiring harness has a blue, a grey, a white, and a BROWN wire. This harness is going out the back and is hooked into the tail light assembly. I didn't remove the lense off the tail light to see which one it is, but you may want to check that out. It's the ONLY brown wire I could find. Good Luck!

On closer inspection, the "brown wire" is actually a four-conductor cable. On the outer brown sheath it bears the legend "Genesis Cable Systems 20 swg" and inside are four separately insulated solid core wires with red, white, green and blue insulation. It goes into a bundle that heads aft, and seems to go into the end-cap inside wall.

This gets weirder every time I look at it!

At least I've cured the poor signal issue on my cable TV hook-up!

Thanks for taking the time to look, Barry.

Frank

Well they must use something at the factory to make "runs", but as to color coding the wires I doubt it. My camper uses the same color wires based on gauge not function (unless supplied by the vendor like the radios). Everything that takes 30 amps is twin wire one green and one white. Everything that takes 15 amps is red and black.

I think they just pull it off giant spools as they wire up the coach.

The slide motors; and tank heaters all use the same green/yellow twin and run bundled together. How you would tell which was which without hand tracing is beyond me.

I figured it out by going onto the Internet and searching on the cable manufacturer. It's the wire from the land-line phone socket in the power bay next to the cable TV coax socket. I may have pulled it out of the protective jacket when I ran a new TV Coax.

With cell phones everywhere now, I can't see ever needing a land-line hook-up, so I'm just leaving it where it is.

Much appreciate the help, everyone.
