If the red and white at the top go to the battery, then I'll bet the (bottom) red and one of the whites go to the converter. And the black and other white go to the TV.
If the converter comes in at the bottom of the distribution block (red wire). The wire doesn't appear to be large enough if you have a 45 amp converter.
Is there any reason you can't move the converter to be in the same space as the existing fuse panel? Then you could connect the converter to the distribution block with the proper sized wire and short ones at that.
Your trailer wiring looks similar to what I had in the Argosy. I've attached a sketch of what I did.

The wires going into the converter are really large. At least as big, if not bigger than the ones in the baby trailer. I'll take a picture today and post it for you to see. If I need larger wires maybe I could just run some directly from the converter to the fuse box but still have the converter be on the other side of the trailer?

I don't think there will be room for the converter, the battery, the potty and all the plumbing in the area around the fuse box. But I'll check and see.

Hi Lindy,

Based on everything Iíve read, hereís the layout of your current fuse box:
Click image for larger version

Name:	Lindy Fuse Panel.jpg
Views:	103

ID:	134707



Basically, the two fuses protect the battery and trailer from each other. They are there mostly in case you hook the battery up backwards.

The converter feeds the red wire coming into the fuse panel at the top grommet on the right side. The black wire most likely goes to the umbilical cord to the TV. The two white wires in the second grommet also go to the converter and the TV. Only place they make sense to go to.

The big wire nut is your ground bus. All the 12 VDC commons are tied together in that wire nut.

The black wires feed the cloth covered wires youíve found, which must go to the lights, furnace, and old pump location. The only way to know for sure which is which is to disconnect them from the distribution block and either use your ohm meter to see which wire is which, or to disconnect them one at a time and see where you lose 12 volts at the other end of the wires.

As far as I can see, there are no fuses between the converter and the 12 volt circuits. That is not good, and there is nothing to protect the wiring, or your converter, other than the internal circuit protection your converter may have.

If this where my trailer, Iíd replace the old distribution block in this fuse box with a new 4 circuit fused distribution panel like you installed in your other trailer.

Do you know the gauge wiring that goes to the converter? That would be the thick red and white wires. It looks like the red, black, and two thick white wires are all the same size, is that correct? They might be 10 gauge, but Iím guessing on that.

How far away from this distribution block is the new converter? Distance in wire feet if you can figure that out. A close approximation would be fine. Asking in case I want to change my suggestions below.


Hereís my suggestions:

Install the converter in its new location. Assuming that this is 10 gauge wiring, install a 30 amp inline fuse on the positive output of the converter at the converterís location. That will protect the rest of the wiring in the trailer.

Install a fuse block to replace the old distribution panel. Use the 12 volt input lug to connect the converter and positive battery fuse to the fuse block.

Run the 3 12 VDC black wires to 3 fused circuits. Use fuses to correspond to the black wire size. 15 or 20 amp depending on if the wires are 14 or 12 gauge.

Connect the black wire from the TV to the 4th fused position on the fuse black. This will add a fuse into the TV circuit. Use a 30 amp fuse if the wire is 10 gauge.

Use the two glass fuses already there to protect the battery. 30 Amp would be good if those are also 10 gauge wires.

That all make sense?

To answer some of your other questions:

1. Why can't I just connect a 12V wire (12 gauge) to the existing water pump wire (black) and run it up to the front where the new water pump will be? That way the switch would still work for it, wouldn't it?. Yes Would I need to put a 20 amp in-line fuse in the wire just to be on the safe side?Not if you use a new fuse block. What I don't know is what do I do with the white wire? Connect it to the skin? Connect another white wire to it and run it to the front where the pump is? And then do what? Do as TG said Ė connect a new white wire to it and run to the pump to provide a ground/common return for the pump.

2. We haven't decided yet whether to put in a real furnace ($$$) or maybe a catalytic heater (are those safe?) so couldn't I just wire nut off the black and white (separately, of course) and have it there when/if I need it later?Catalytic heaters are safe, as long as you remember to have a window cracked open to provide fresh air. They will consume the oxygen in the trailer if the trailer is totally sealed up. In the fight for oxygen, the heater will win (not good for other things that need to breathe).

3. The wire in the cabinet at the front of the trailer (11.6 reading) isn't needed for anything since there are already enough lights there so could I somehow bring that wire down through a wire chase and around the perimeter (all the way around) over to the fridge and use that as my maybe-I'll-need-it fridge wire? Just have it hang out there until I need it?Sounds good to me. Use the same gauge wire it is now to add the extension. Run both the black and white wires so you have a complete circuit.

4. Can I run a 14 gauge wire from the connected wires in the closet to power a reading lamp over the bed? Yes If I put the 14 gauge wire in with the black wires, how do I ground the light? Put the ground wire in with the white wires in the wire nut? Iíd extend both the black and white wires from the closet to where you want your lamp and use the white wire as the ground/return.

5. Finally, a bit off topic, there is a little tube sticking down in the back with a little threaded hole above it to the outside. The PO said this was a vent tube for the battery but when I blew on it I couldn't get any air to go through it. Any idea what this might be? You put your mouth on it and blew into it??????? Brave lass you are! No idea what it might for though. Looks more like a drain than a vent.

down time...

I have to go to Denver tomorrow to pick up Gene's grandson who will be with us for about 2 weeks. That means that probably not much will be going on in the trailer.

I thought I might try to find a new fused distribution panel while in Denver like you suggested but, of course, I have some concerns.

1. All the 12VDC wiring looks like "regular" copper 120VAC wiring. What gauge wire should I get to connect to it to extend the wires to the pump and fridge? 12 gauge? Is it safe to assume that I can connect the "normal" 12 or 14 gauge wires to the copper wiring (black and white) that is throughout the trailer? Connect with those little squeeze connectors and/or the shrink stuff or use wire nuts?

2. I'm almost sure the wires going to the converter are 10 gauge but I will try to check it out tomorrow before I leave.

3. The new converter, in wire feet, is probably12 feet away. It goes from the fuse box into the wall and then goes through a pipe back to the other side of the access compartment (probably 3'-4'), then another 5-6' through the wall and maybe 3' of wire outside the wall. If it would be better to have it closer to the fuse box, I will move it. I haven't yet put in the 120VAC wiring so I could put it's outlet on the floor and have it maybe 3-4 wire feet away from the box. If need be I could move the battery to the other side?

4. There is a fuse built in to the converter (blue) but I think it said it was to protect it if it got wired up backwards.

5. What is the 12 volt input lug that I would connect the converter and positive battery fuse to? Is that the lug on the left that comes down from the glass fuses with the red wire?

6. I forgot I need to get a propane detector. I know that takes a tiny wire (16 gauge) and 5 amp fuse so should I get a larger distribution box - maybe one with 6 connections? I've posted a picture of the fuse box I got for the little trailer.

That should give me enough to think about on my trip to Denver and back. Maybe I can get all the supplies I need there and get started while the grandson and his PawPaw play.

Thanks for holding my hand with yet another complicated (for me!) project.

The cloth covered wire is solid wire; crimp connectors are designed for stranded wire. Wire nuts will work, so will soldering the connections as long as you clean the old wire well.
If the wire going to the converter is 10 guage, limit the fuse size to 30 amps.
Moving the converter is your choice.
The fuse in the converter is reverse polarity protection.
If you install a new fuse block, connect the converter, battery and TV positive wires to the big lug on the fuse block. Where the black wires are connected on the one in your photo. These three wires need fuses ahead of the connection to the fuse block. Refer to the drawing I posted above.
Instead of a 50 amp use three 30 amp fuses. You could use the 20 that is there for the battery instead of a 30.
You could remove the wire nut and connect the commom/ground wires like you did on the fuse block in the pic. That is where all of the white wires connect in the pic.
I would think you could find a fuse block along with an AGU fuse block like the one I used in an Automotive Stereo Shop or a well equipped auto parts store.
Take some photos of what you have in the Traveler with your iPod Touch and carry them along.

Here is a pic of a typical AGU fuse holder. I'll email this to you so you can have it in the iPod.

converter wire size

I compared some #10 wire that I had (assuming I had put it back in the right box - the wire didn't look very big) with the old wiring on the new converter and the old wire is larger than what I'm assuming is #10. But, I then looked at the converter wiring in the little trailer and it is HUGE. Much larger than what is in the new trailer.

Should I get the same size as what is in the little trailer or is #10 (or whatever it is) ok?

I've attached pictures of both converters. The one with the red and white wire is the old wiring in the tradewind. The one with the black and wrapped-in-white-tape is in the Traveler (apparently I didn't have red and white wiring ). For comparison, the yellow in the Traveler picture is #16 and the little white is #14.

The converter is rated at 45 amps. You need wire that is capable of carrying 45 amps at least.
I'm not sure how far the battery is from the converter. But you could consider this. Install the AGU fuse holder in the same space as the converter. Connect it to the converter with wire capable of carrying 45 amps. I would recommend #6 wire. Then install 30 amp fuses in the fuse holder.
From the other side of the fuse holder connect the new fuse block to one fuse and the TV charge line to the other fuse. Use your existing 20 amp fuse holder with the red wire for the battery as it is today. I can draw up a sketch if you like to show you.

I'm confused as to where you want Lindy to install the 30 amp fuses.

Here is a rough sketch. This way the 30 amp fuses protect the smaller wires that go to the converter, battery and TV connection. It would require wire that can handle the 45 amp capacity of the converter between it and the AGU fuse block and to the chassis Common/Ground. Since you could conceivably draw the full capacity of the converter without blowing a fuse. 30+30=60 amps; converter limit is 45 amps.

Wiring Change

Because you have what is known as a floating common; black(red) and white wires going to all devices, I would recommend wiring the trailer per attached drawing.

Looks good TG!

Lindy, once you can back to working on her, let us know if you have any questions.

Going back to crib making now. I'll post pics when it's done.

Thanks for the drawing! It will really help.

Since I was unable to find either a fuse block or a fuse box like I have in the Traveler, I will have to order them from the place I did before. Is the fuse block I have pictured ok to use? Could I then put all four 30 amp fuses in the one box and run the wires from the converter then to the other connections or do I need to separate those fuses and have two blocks? They're cheap enough ($8.72) so I can get two if I need to.

I also took a photo of the fuse box that I have in the Traveler (attached PDF) and put in what I think I need to do for the new trailer. I'm assuming all the white wires that are in the large wire nut would go to where the white wires are in the photo?

Are the black wires going to the battery? If not, what do I put there?

Since I'm putting in the new fuse box and fuse blocks, should I just completely take out the old fuse box that is there and run new (#6? #10?) wiring to the battery from the box?

Also, since I will be using the existing wiring (black and white solid copper) for the lights, do I solder the connectors to them or solder a stranded wire to them, cover it with shrink stuff, then squish the connector to the stranded wire?

With 3 spaces for the lights that leaves just enough spaces for the propane detector, water pump and fridge. Or, if I use the existing wiring for the water pump and the wire in the front of the trailer for the fridge, do I still need to have a space for those in the box? Those wires are the ones that connect in the closet. The lights are on a different circuit (I think).

I will have to wait about a week for the fuse boxes to come in so I think I will start on the 120VAC wiring until it gets here. At least whenever I'm not entertaining a 15-year old grandson... Teenage boys are just downright silly!

Or this one?

It comes in 2 position ($15.63) and 4 position ($25.29) fuse blocks.

This is where I'm looking:
