Trailer brake problems!

Dur05 · 01-25-2013, 05:21 PM

I was hooking up my gooseneck which I've hooked up several times in the past and now I'm having problems. All my fuses are good and when I hook it up all my lights and everything work but my brake controller reads not connected and my trailer brakes for work. But the weird thing is all the lights work. Help!

It could be many things. What brake controller do you have. Do you use the 7 way on the rear hitch or do you have a plug in the bed? I would start by using a test light and see if the bottom right pin on the trucks plug is getting power when you step on the brake or squeeze the manual lever.

What kind of brake controller?

Check all the wiring, clean the connectors.

I have a plug in my bed, yes i have used a test light and all bring power except the bottom one and the bottom left, even the brake lights work but the controller still reads not connected. I'll take a look at it tomorrow im not sure what brand it is but it goes off the pressure you put on the brake pedal instead of going all the way up to the number you set it on, thats what i like about it compared to my old controllers.

put some elect grease on it. It might just be some dirt or water in it. I have had that happen a few times. The other option is it may be the controller. I had one go bad before. If you do a search on youtube they explain how to test the controller. It is something like cutting the blue wire and testing with a test light. I dont remember off hand but that is how I found out my controller went bad.

Does it look like this?

Either way take a test light and stab the blue wire coming out of the back of it and see if it says connected and try stepping on the pedal and see if it lights up. If it doesn't you have a bad controller. If it does try plugging the trailer into the rear hitch plug (I'm assuming you have one) and see what happens. Do you still have the factory style snap on the back 7way and is your plug in the bed a nice plug in T kit or is it spliced in?

No, its not that controller. But i went out this morning plugged in the trailer for shits and giggles and what do you know the brake controller reads connected and everything works

It may be the first signs of the controller going bad.From my experience.

Are you sure it works off of pedal pressure? That is the only one I know of that is still in production (besides the factory controllers). That's the best part of the factory controllers, it's too bad they're not compatible with all electric over hydraulic brakes.

I think the OP's just describing a proportional controller versus a cheap timer based controller.
