electric trailer brakes issues

[Montehall]

I've been trying to troubleshoot the electric brakes on our stock trailer.
if we hook up our truck to the trailer, regardless of if the controller (Prodigy) is installed or not, the brakes on the trailer will randomly lock up. We ended up having to pull the brake wire out of the plug so they no longer got power.

I'm attempting to determine if it's our truck (2002 F350) or the trailer that has a wiring issue.

I'm kind of leaning on the truck having the issue, since the brakes on the trailer don't lock up unless the wires are connected to the truck.
The brake controller will usually show the trailer as not connected, but the brakes will still randomly lock up.


Is there a way to simulate a trailer on the 7-pin connector on the truck? or go the other way, and provide a simulated brake voltage to the trailer?

or does anyone have another idea?

C5silverbullet did offer to let us try a truck off his lot and see if that helps, and I really appreciate the offer, it's just been hard for us to get time to hook up and make the trek out... but it may come to that before I go to get my car.

Seems to me there's a trailer expert on the other forum...thought about PM'ing him?

Place meter between brake wire and ground. Under full brakes ( push controller handle to the stop) You should have 12V.
If you read 12V without pushing the handle, you have a truck wiring problem.

my brake controller will only output if a trailer is connected.

On most installations the blue wire goes to the brakes from a 7 pin connector. The white wire is usually the ground.

my brake connice personer will only output if a trailer is connected.

Go through the adjustment listed in this manual.

Maybe this will help. (http://www.championtrailers.com/brkart.html) Scroll down to trouble shooting.

lol..that's funny...all of the above was typed in as C O N T R O L L E R (without spaces of course)

connice personer

Yeah, when I first read the thread I thought you were talking about some kind of technical term associated with a trailer hitch. :rofl:

This forum's funny like that. I have tried to reply a couple of times where it doesn't change my words, it won't even let me reply. Gives me an IE 500 error page. I eventually figured out the words but it was weird.

looks like it's fixed (the word controller, not my brakes.)
