I posted in the wrong forum first time.

Fellow RVer is coming by to compare my brake wiring at the hub to his. He blew a tire. 2010 Mountaineer 5th wheel 324 RLQ (Yes, we have the same one)

I just looked at mine. I have 2 white wires dropping out of the floor to drive side axel. (side the tire blew) I can't see a difference between the 2 wires. No markings.

They drop to the cross over wires to the passenger side, which one is a brown color, the other white.

So, How do we figure out which white wire goes to the brown wire and also the other white wire to actual brake?

wire 1 = white to brown and white
white 2 = to white

Thanks

 

Just so long as you keep the magnet wires in parallel you will be fine. The magnets don't care about polarity.

By convention, my expectation when working on something is the white is the ground lead. But, even if you have no idea and hook it up wrong, the most that can happen is a fuse will blow. Then just change reverse your connection and put in another fuse.

Thanks Steve and Denny.

Got the wire that crosses over clean enough to see that one has a black stripe. so that is a good thing. He didn't have anyway to check for power. I did in my truck, but, sadly, we have one vehicle and wife was at work! Figures.


I haven't spoken with the guy since, so not sure what he wants to do from here.

 

Edit: wrong thread

 

As RVPULLER said it doesn't matter. Just hook 1 wire from hub to either and then hook 2nd wire from hub to the other, there is NO ground on the magnets and they will work with either polarity.

 

sorry to hijack.

is it Common for brake wire connections to ONLY use wire Nuts ? and not solder them..

right after dealer replace all my brakes under used trailer warranty... I seen the new wire nuts.. SO I removed them and soldered all and also the break-away circuits.

 

My 2006 has wire nuts.

 

never saw them soldered.

Thank You ... Gentlemen.

in my world,

if it does not start.. it's an inconvenience...
if it does not stop.. it's a disaster.

 

Something I seen posted some where.
On planes they are can not solder wires by law. Because of the vibrations the wires break just after the solder.


Again something I saw posted.

wire nuts offer NO weather protection.

 

...but on aircraft they use safety wire on all nuts, bolts.... wires are terminated in a molded connector which is bolt and nutted to each device.

 

There are weather/water proof wire nuts on the market. The wires slip though a plastic flex cover where in side of the nut is filled with a silicone that water proofs the connection.

 

They do it seal them with silicone after they are installed and everything is working.
