Brake controller

[owenkicker]

my integrated controller is set on 10 but when coming down a hill with 3 to 4 horse in tow I only have 3 of the bars light up on the controller. but when I use the slide lever I get all the lights and you can feel the trailer stopping the truck
I called the dealership and they told me that the controller runs off the speed of the truck the faster your going the more voltage is applied to the controller. does this sound right to any

wow, that doesn't sound very good to me. I guess thats why I see so many trucks adding a brake controller under the dash and not using the factory one.

I just hooked up my travel trailer for the first time to my 06 F-350 and my brake works based on how much pressure I put on the brake pedal. Doesn't seem like speed has anything to do with it.

I just talked to the dealership again this time to a mechanic. said I have a ground problem. said to check by running a extra ground wire from truck to trailer
or I have a bad magnet. check by unhooking all of them and check the ohms on each should have .4 to .6 ohms on each
if higher replace that one

good to know
