Dump Trailer Brakes

I own a 16' gooseneck 14k dump trailer. I noticed my P3 brake controller cut in and out reading no trailer connected( it comes up red). Now it reads no trailer connected at all times even though the trailer is connected and the lights all work correctly. I tested plugging into 2 of my dads trucks and both brake controllers wouldn't "read" or work on those trucks.... but the lights did work.

I had an issue before and I think it was related to the magnets wearing uneven and now there is no connection??? The magnets are maybe 1 year old. That's all I can think of

What harness plug? The plug at back of truck...or the trailer plug? It has to be the trailer and nothing to do with the truck b/c it did the same thing on 2 different trucks. If it is a bad ground....then it has to be a ground associated with only the brakes....because the lights work

Why don't you just take the wheels off and see what you can find?

check the magnets first, mine did the same thing, magnets were wore out and causing it to read bad and not work. simple fix, just replace entire brake on each wheel not just the magnets, cost is not much more. brakes may have been adjusted a little to strong to cause it to wear out in a year.
