Any RV tech's out there? I seem to have problems with my brakes and just not sure where or how to look. I'm quite mechanical, but electric brakes I have no clue about. I've hooked up my 27' trailer to the truck that has a Tekonsha (I think). I've followed the instructions to level the controller and then set the power...but what happens is the trailer brakes will hit HARD and lock everything up. I back off the power dial and then there's no brakes. When I manually squeeze the controller..same thing; the light will ease from green to orange and then BAM full on red and brakes lock up again. Does this sound like a faulty controller? or faulty trailer brakes? I just need a few pointers on what to check and what tests to do. Also: second issue. When I last parked the trailer, I didn't notice that the brake-away swith got yanked out. The RV was plugged in, so it didn't drain the batteries. But when I plugged it back in, the box heated up, smoked the wires and now it doesn't work at all. Just a bad box? Any help would be appreciated.
