Brake Problems 1985 Sovereign

I have a 1985 Sovereign 25 footer with defective curb side brakes. It appears
there is a short in all four wires going to the two magnets in each brake. When the wires are seperated on the curb side, the street side brakes work
great, but the short is still there on all four wires. All four magnets in each
brake appear to be in good shape with practically no wear. I have lifted the covering inside the kitchen sink and see no problems with the wires, ie, no
trouble spots (burns) nor any chaffing of the insulators.

I can not determine how the wires go towards the front of the trailer after leaving the sink location. This of course would be to check for the short. There must be a junction box somewhere in line from the sink location to a point where the wires go to the hookup cable to the vehicle. I'm sure there is, however I can't find it.

I am tempted to slave off the good street side, go under the trailer and terminate to the curb side magnets after disconnecting the defective wires. Would this work if I can't find the short?

Any help and suggestions would be appreciated......grayman

All the brake wiring is within the underbelly.

You could have two possible problems.

The first would be the wire has been pinched within the underbelly, as it goes to the curb side.

The second could be a defective magnet. They can and do, develope a short within themselves. Not often, but not impossible either.

If it's not the magnets, then pulling part of the underbelly, will expose the wiring to you.

I think if you remove the goucho, you can find more wires (at least on mine you can)
I would try my best to correct the wiring as it was built, but if you can't , I would think that "slaving" as you put it off the good side would be ok. (ie running an additiona jumper wire) it's just one main Power wire that excites all the brakes at the same time.

The only issues I see with "slaving" one set off the other is possible line loss and a possible difference in stopping power between the two sides. Electricity is lazy, it wants to go to ground he shortest possible way. You will have power to the "bad" side, but I would be concerned that the wiring plan could be detrimental in a panic stop situation.
