Ford Truck Service - Mitchell, SD

[HappyRV]

Currently travelling west from NY to Yellowstone..having issues with trailer warning lights in truck...Jack's Campers in Mitchell changed the plug yesterday, sent us on our way...only to have the same lights come on after 20 miles or so...we are going back there Monday for further exploration...they are checking connections in axles...but if its a problem with the integrated breaking system on the truck..there's nothing they can do...I've had limited internet access and can't seem to find any authorized Ford Truck service anywhere close...Jack's cannot recommend anyone...Does anyone have any ideas...we're thinking of forgetting Yellowstone so could really head in any direction!!

Found Boyer Truck in Sioux Falls...we'll head that way if the problem is with the truck.....

What is your tow vehicle? If it is a Ford, what partcular message is the dash giving you? If it says "Trailer Wiring Fault" then it most likely is a bad ground ON THE TRAILER. Found my ground wires were loose in the junction box in the hitch box. Problem was intermittent...if I stopped and wiggled the 7-pole connector in the bed wall, all was fine for a while, then it would start again.
Can you find another trailer to hook up to and see what happens?
Hope it is that simple for you, will be kind of stressful if you lose the brakes on Teton Pass.

it could also be a ground wire shorting near one (or more) of the wheels. Typically the RV manufacturers run the wires thru a bracket hole near the wheel. After years of traveling these wires rub against the frame and eventually short. Check these wires and repair if needed.

Thanks Joe .. We are at the service place mow....they are redirecting the wiring to the trailer brakes, bypassing the axles ...also checking junction boxes etc...we are crossing our fingers for an easy fix!!

Good luck to you...most Ford dealers will say its the trailer; most trailer places will say its the truck. No way to fix without the two units at the same place at same time. I really have not heard of any problems with the Ford IBC after the 2005 model (first year). Can be frustrating trying to find the problem. Several people I know have replaced the truck socket AND the trailer harness, only to have the problem still. Diligent tracing to ground connections has been the answer for them, and me. One of them was a GM and it was the harness ground to the truck that was dealer installed.

Even more frustrating is that theres no way to check it for sure prior to leaving...we drove 10 or 20 miles the other day, after the first repair, before the warning light came on again!

Suggest you arbitrarily direct them to REDO all the ground wires where the junction of the 7-pole harness to the trailer wires. This means disassembling all ground wires where they are connected to trailer wiring and putting them back together such that there can be NO DOUBT there is a good electrical contact where all such wires meet.
Hopefully, that is where your problem is, and not under the trailer somewhere.
Maybe I am out in left field on this, but it sure solved my IBC problems. The ground wires in my Suites were all in one screw-on connector and there were too many wires in the same connector to keep good contact--the higher amperage of the controller would not work even tho all the light grounds did.

Well 10 hours later...we're back on the road...bad magnet was the electrical issue...also found bad brake pad...all wires checked in junction box ...keep your fingers crossed for us!! We will only drive an hour or two tonight... Just to get out of dodge!! Our friends are in rapid city ...we'll go to the badlands tomorrow and maybe catch up with them by Thursday.

Just goes to show you how much I know...

Happy for you to be back on road, even happier you found the brake pad--that could have been trouble later.

Enjoy the trip!
