I am looking for a wiring diagram of the 110v circuits. I went to the Library and looked the owners manuals and they only show the DC circuits. I am trying to find out what the 110v wire goes to that runs up through the wardrobe then into the upper cabinet above the bed on the left side of my 2806C. The 12 gauge wire goes from the cabinet up into the ceiling. There already is a huge wiring harness in the shower area that powers the air conditioner and pretty much everything in the upper part of the trailer. I cannot find anything other than the air conditioner that runs on 110 volts in the upper portion of the trailer. The trailer was built with every available option installed so I don't think it is for a "future" option.

Romex wiring is used through out the trlr.
It looks like wire used for 110v, and can handle 110v.
My tlr has 12v in that wiring also.

you are correct that only thing in the top that is 110v is the A/C. Possibly a tv connection/ antennae???

110v is also in the bottom for the inverter/charger, refer., plug ins

everything else is 12v, ie: lights, fans,

use a multi tester and check for the voltage.

Jean, the "wire bundle" you speak of in the bathroom is probably all the 12V feeds and ground for things like the running/stop lights, interior lights, ventilation fan, etc. The Air Conditioner is probably fed by a heavy black insulated wire that may well run beside the "wire bundle". It would be a 3-conductor wire that looks a lot like a heavy duty extension cord.

There is nothing I can think of in the top other than the Air Conditioner that uses 110 AC power. But, if you have (or had) a solar panel up on top of the trailer, that 12 gauge wire is probably the feed from the panel to the solar controller, unless it was removed too. If it IS for a solar panel, it will probably be 2-conductors and covered in black insulation too. A fairly useless 15 Watt solar panel was an option in my trailer and probably yours too. It would have been mounted on the roof at the front of the trailer.

I say the panel is useless, because 15 Watts is really only able to maintain a battery's charge when the trailer in not in use. It will NOT charge the battery during camping.

I installed 2 - 100 Watt panels on the roof of my trailer and they do a good job of keeping the batteries charged during dry camping. To get the charge down to the batteries, I ran a pair of 10 gauge solar wires from an upper cabinet down behind the couch and then through the floor to the battery compartment. The 15 Watt panel would be happy with the lighter 12 gauge wire.

Jean, I have the same trailer as yours. The wire you refer to is for the air conditioner. If you trace it down to the space between the wardrobe and the wall, you will find that there is a plug. It was designed to be unplugged and stored in the upper cabinet when the unit is down, much like the main power cord for the trailer is stored when towing. There are actually two receptacles in that space on the side of the wardrobe. The one for the air conditioner is on a separate circuit breaker from the other receptacle. It's not the easiest spot to look at, but you can see it by getting on the bed, then looking into the space between the wardrobe and the upper wall.

I had to remove the cabinet over the sink area because of water damage within the wall. I am in the process of repairing the leaks. my issue is that I cannot remember what the yellow wire hanging out the top of the wall is for. it was hooked up somehow with the lights in the cabinet. it has a black wire attached to the end of it and I think you hook all the black wires to it. after I took down and disconnected the cabinet wires, I now do not have running lights and the back light on that side of the trailer does not work. I had to move the trailer and I only have one light on the right side of the trailer.

Lisa - if you've lost virtually all of the lights in the rear of the trailer, that wire is probably a "common" ground wire. If you have a "bunch" of black wires that are not connected to anything, I'd go ahead and connect them to the black wire you have at the end of the yellow one.

Or, if that black wire at the end of the yellow one is still connected, then it's probably the ground for the light that is still working. You could test this by disconnecting it and see if that light stops working. If so, that would confirm it's a ground line and you could connect all the other black wires to it.

Those wires are not 110V. They are part of the 12V DC system.

Good Morning Jack,

Hope all is well with you this morning. The black wire that is on the end of the yellow is not connected to anything, it is just hanging from ceiling. I do remember taking a screw out of the wall but lost the picture and video showing me what I did prior to taking the cabinet down.

You guys have been amazing on this forum.

Bless you

Lisa, what year is your trailer? There MAY be a wiring diagram in the library for it.

I just love taking phone-photos of something, usually when it is too dark and I dont have a real good angle, before I dismantle something or while I am dismantling something only to find I have no idea what I am looking at when I use the photo to put it back together.

Jeanj, I have a 2705T with all the bells and whistles which would be a lot like your 2806, but the power outlet for the A/C is located on the bottom half of the trailer, drivers side, and on the wall dividing the bathroom and bedroom. On the passenger side and on the same dividing wall is a 110 outlet for a television.

Lisa, it's a puzzle. The wiring diagrams show "white" wires as the ground circuits.

I STILL suspect your black wires are grounds. You would have completely separate, different color wires going to the "hot" side of any of those rear lights, since they have to operate independently. They ALL could, however, share a common ground.

If you could take the cover off one of the lights, you might be able to see what color wires go to it. If there's a black wire, it would tend to confirm my hypothesis.

I had to take one of my tail lights off (needs a screwdriver once the cover is off) to find a wiring fault and it's not hard to do.

- Jack

Thanks Jack,

I will check my lights like you said.

now my battery keeps dying. i need to purchase a new battery. do anyone what type of battery I need to purchase. Automotive or marine?

Marine is preferable to automotive. It does better under "deep cycling" conditions, but NO battery really does well if deeply cycled.

An automotive battery is designed for engine starting.

- Jack

Lisa, that picture you posted of the yellow wire looks more to me like an interior light circuit. Do all your interior lights work?

- Jack

If your 92 Funlite has the curly power cord that connects to the upper half this manual may work for you. It shows the yellow wire to be the power to the the interior lights.

I know I have the same problem it's frustrating . the pics just don't look the same.

Yes Jack it is for the interior lights.
