TV cable diagram needed

[Melorene]

I have a 34' 2008 coach and in the owners manual, there is no wiring diagram for the TV cables. many are color coated but where they go is ?. I am told that the remote sat antenna connection is on the passenger side with a stainless steel plate that says Winegard which is next to the TV jack for an outside TV but I do not get any reception to my Motosat no matter which position I put the 5 black switches in the cabinet to the left over the drivers seat..

If you are trying to get a signal from your roof top sat antenna. The remote sat connection is for hooking up a separate sat antenna in case the one on the roof is blocked by something or is not working or not there. The tv jack uses the signal from your rear tv. Plug the outside tv cable into the tv jack and if using sat select a channel on your rear tv. The outside tv will show the same channel.
If you are trying to set up a remote antenna there may be a cable problem. The owners manual shows the buttons to push.

I am trying to connect a remote antenna and want to check continuity on the cables to the panel and find out where they are supposed to go..

On my coach the cable (purple) from the portable sat connection goes to a splitter thats behind the front tv. Out of one side of the splitter (yellow) to the front tv A-B (roof-portable) switch then to the frt sat receiver (still yellow). From there to the frt tv. The other side of the splitter (orange) goes to the A-B (roof-portable) switch for the rear tv than to the rear tv sat receiver. From there it goes to the rear tv A-B-C (sat-cable-ant) switch out to a splitter thats behind the frt tv. One side to the rear tv (blue) the other to the exterior tv (black). It's confusing but thats what I found using a tone generator the trace the wires. I didn't think that a sat signal would work thru a splitter but have not checked to see if the portable sat connection works. Hope this helps.

My '04 coach documents package included a schematic on the entertainment system. Your system is much different than mine, but maybe the basic color codes from it might help. Hopefully they didn't change that, although where they are connected definitely changed. The '04 coaches still used the Winegard switch box, and most coax connections went to it. It had one other A/B switch that selected if the roof satellite dish coax or the auxiliary dish coax went to the satellite receiver. (And it was wired wrong at the factory.)

Here is the color code from my schematic.

Portable satellite - Purple
Roof satellite - Green
Over air antenna - White
Cable - Red
To outside TV - Black
To bedroom TV - Blue

If that doesn't help (which is likely) there is a thread somewhere on this forum about a Wire Tracker. That should help trace the wiring.

Good luck!

The other Jim's system is likely more like yours, so ignore my post. My system didn't use any splitters. But it indicates that the old basic color codes I had were still used.

Well, I took apart the winegard input on the right side, found the color of the cable a and used one of the 2 ways in the cabinet, bringing it into oneside and the output from my motosat controller on the other side and the center to the Dish DVR..I don't use cable TV so if it interferes with that, no problem.. thanks for all the replies.. it is all working now..now to fix the roof lead under the AC I have had since it was new...you gotta love RV's..Mel

Melorene,

JLMunsil mentioned using a tone generator to trace out wiring, which is a very good tool to use for this purpose. I've used one for many years in the telecom industry and at home. See this link for a YouTube demo of its use:

YouTube - How to use a tone generator and probe to locate cables

Although this YouTube video focuses on telephone wiring, you can use this technique for almost any type of wiring. You don't need a telephone jack to plug into. The tone generator also has two clips to hook onto one end of the pair of wires that you need to trace.

See this link for one to buy on Amazon:
Amazon.com: PRO3000 Tone & Probe Kit: Electronics

By using a tone generator and probe you should be able to create your own wiring diagram for the entertainment system.
