Brake Controller losing power
Good afternoon,
I have a 2018 F250 Platinum -
Up until recently its been a perfect truck. It recently however has developed a flaw and i cant seem to find anything anywhere else about it. It features the integrated brake controller and normally with a 16 ft Box trailer with 2 lawnmowers, 2.0-2.5 is enough to really grab the brakes and help it almost pull too much on the truck. When i grabbed the trailer the last few times, I've developed the problem that at 3.5-4.0 I am JUST STARTING to feel it slightly grab. Thankfully the brakes on the truck are strong enough to stop it without problem but i would like it to work like it did for the bigger trailers. Any ideas? I've seen some mention of using a bigger fuse to solve it but that seems like a bad solution to a small problem
As a side note: The 7 pin connector is clear of corrosion on the truck end and the trailers plug seems mostly clean with a little oxidation. Nothing more than you might normally find. Found similar braking issues on my dump trailer which has a almost brand new plug

My 5th wheel went from 6->10/medium over the last 10k miles of towing.
Hint - it wasn't the truck. Adjust the brake controller until the brakes are working. There is zero point in leaving at such a low level and then saying the brakes don't work! Hit the plus!
And check the brakes on the trailer - that's far more likely the problem then the truck.
After I had the brakes rebuilt on the 5th wheel I am back at 6/medium. Imagine that.

Thanks for the reply. Found the problem was as SDcrewzer had mentioned. I set them at 2.0 on the medium mode and that is the point where it isnt dragging on the truck. Trailer also only had around 500 miles between when it was working fine to when it was starting to act different. Must have changed accidently
