Trailer brakes/controller acting funny
Hoping someone can shed some light on a recent problem I have encountered. I had bought a trailer real cheap and then re-wired the entire thing and also put new brakes on. The problem I am having is I believe with my brake controller. If I pull the pin for the breakaway, all 4 lock up (dual axle). If I use the manual over-ride, all 4 lock up. The problem I am having is when I try to use the brake controller and the standard brakes. If I leave the wiring as is, I get nothing no matter how it is adjusted with the dial(on two different brake controllers). When i first took a look underneath, I saw a wire that someone had jumped from the white wire on the switch on the brake pedal to the red wire coming off of the brake controller. If I hook that back up and try it then all I get is full brake as soon as I tough the pedal.
My questions to start are....
1. Should I have to jump any wires on my truck for this?
2. If so which ones?
3. Should the white wire be reading 12 volts right away after engaging brake pedal or should it be proportional based on the amount of push on the pedal?
Thanks guys. It's a 10,000 pound trailer so I really need the brakes.
