There should be 0 volts coming from the breakaway switch. Since it is not activated.
Depending on the age of the axles, you may not be able to find repair parts. If there is a shop there that does work on boat trailers. You may luck out.
If the trailer has the original wiring, this should be the only place the wires are terminated. However, there will be splices under the trailer for the wiring to go to all wheels.
And yes, the common/ground should be a complete circuit to the house battery as well as the TV. Since the lights are working when you test with the house battery and jumper, I would say that that part of the circuit is good. You should plug into the TV and test the lights, etc. if they work, you have a common/ ground return path. Then it is just a matter of locating the problem with the brake wiring.

From reading your reply it sounds like you are convinced this is more of a wiring problem and not burnt up magnet(s) or other faulty components, correct? Are you fairly certain that burnt up magnets or other components from sending 12 volts down the line would NOT cause the brake controller to not see the trailer?

The wiring problems I'm dealing with now may be a result of my yanking on cables to initially troubleshoot what turned out to be my miswired umbilical. I pulled out the trailer side socket during that and also opened up the wiring box inside the front of the trailer. And just now, I may have unplugged another cable inside the wall (doh!) or pulled one to the surface that was already loose or unplugged.

The picture above shows the wiring I'm looking at now. There is the two conductor cable coming up from the floor -- that is the main brake cable.

The black lead runs up to the trailer side umbilical socket and to the pin for the brake controller. That is split to the blue wire which runs to the breakaway.

NOW the white side of the two conductor cable that is spliced to another short white wire and finally an orange wire with bare end --- that is what I just pulled from inside the wall. Is that a negative/ground? This along with the black wire described above runs to the axles and is split off to each wheel's brakes.

I need to know if that is the negative/ground because if it is maybe that was my issue! I'm wondering if I can just ground it to negative and test again?

The yellow wire with the crimp on it that terminates... That may have just been floating there as it doesn't seem like the open end has been crimped before. But I'm not sure. Maybe that's where the bare wire was attached in the wall?

Unfortunately, I'm wondering if I am going to have to crack open the wall and remove that panel from the inner shell to sort this out. Except if it is obvious that the bare wire is for grounding then maybe I can just wire it another way.

Good news!! I grounded that wire and now my controller says I have brakes! I have not yet gone for a test drive as I have to make a permanent repair first. I'm thinking about splicing it into the ground coming off the trailer side umbilical plug. Except it probably should be grounded a bit better to the house batteries in case of a breakaway. Well, I guess that wire on the plug does go to the house batteries....

In any case, thanks so much for the help in troubleshooting. Crossing my fingers that the brakes will be fine now.

I'd get rid of all of those solderless connectors, and solder all the joints. I lost my love for solderless connectors back in my motorcycle days.

Also reducing the shear number of connectors in a single run reduces the likelihood of wiring issues in the future.

Thanks - yeah I cleaned that up a bit. Someone must have been short on wire when they did that.

CA Tallguy,
1. Do all of your other lights work properly on the trailer? If they do, that says that you have a good solid ground and the positive wires to the lights are fine.

2. When you are reading from positive to the brake light circuit, that just says that you have a 0.2 Volt differential between the brake controller output and the positive battery terminal. If you unplug the trailer from the tow vehicle and probe the connector on the tow vehicle, do you get a reading of about 12 volts? I suspect that the answer will be yes.

3. Check the trailer. I suspect that the trailer wiring is where the problem lies. You need to unplug the trailer from the tow vehicle and disconnect the battery and use your ohm meter to determine where the wire is open between the plug (umbilical cord connector) and the brakes themselves.

I hope that this helps.

Steve

CA Tallguy,
I've re-read your posts more carefully and it appears that you may have fixed the problem.

Thanks Steve - yes the problem was a bad ground connection on the brake line. There was a loose splice inside the wall but thankfully I figured it out without having to go in there.

It's all good - your insight could help someone else coming across this thread later.
