[QUOTE="dustinz85, post: 997974, member: 3649"] I hooked up to our trailer tonight and the trailer brakes were locked up. So I unplugged the trailer and got the multimeter out and started checking the pins on the plug. With the key on there is 12v to the brake pin, regardless of where the brake controller is set at. So i unplugged the controller under the dash, with the key still on I still have 12v on the brake pin. I turned the key off, no power at the brakes and still have the battery charger pin having power. The rest of the pins have normal power when they should. Is there an issue under the dash that I should look at since the issue only occurs when the key is on? I recently put a new 7 pin plug on the truck, I checked the wires and nothing is touching, and according to the wiring diagram everything is where it should be. Anyone every experience this before or have any idea where to start looking other than the plug? Thanks in advance guys. [/QUOTE]
