Electric Brake Controller Shuts off Truck
If there's already a good post on this I apologize. I didn't find it.
I just got off the phone with Derrik who is the technical guy for Husky Brake Controllers. 800-344-3230. I explained to him that I have a Husky Journey HD electronic brake controller in my 2000 F250 7.3 and that when I am towing my toy hauler and I apply the brakes, the truck shuts off. In particular, I can sorta change the time that it shuts off by adjusting the electronic brake controller Output and Ramp Time.
Derrik explained that the newer electric/electronic brake controllers with their high-power outputs throw out a bunch of "noise" or "EMS". In my situation, it's the Dark Blue wire from the electric brake controller sending out a bunch of "EMS" that gets picked up by the transmission wiring and a bunch of electronic "junk" ends up making the truck shut itself off.
The fix is pretty simple. You have to re-route the output wire from the electric brake controller. By routing it on the outside of the truck frame rail, you use the truck frame rail as a "shield" so that any junk transmitted from the electronic brake controller output wire won't get picked up by the wiring harness at the transmission and fed back to the computer or whatever part it is that ends up shutting down the truck.
My truck is a 2000 F250 4x4 7.3. Derrik indicated that it's somewhat common on this body style with the 7.3 when a high output electronic brake controller is installed.
I haven't torn into this project yet, so I don't know if cutting the Dark Blue wire at the controller and at the trailer connector and running a brand new wire outside the frame rail is the easiest thing to do, or if I can access the Dark Blue wire inside the factory harness near the transmission and simply wrap it up with some aluminum foil and ground the aluminum to the frame to effectively make my own shielded wire.
If it stops raining and I get a chance to tackle this project, I'll let you know what I find. If anybody has already been through this, please post your results. I didn't find much on my Search prior to posting, but I'm not always the greatest when it comes to effectively Searching for earlier posts.
