ok everthing was working fine for a couple of months now this.<br>That large trailer connector that comes stock it has a positive and negative treminal inside it along with lights,left,right turn,stop. any way with the volt meter on DC when i touch the negative and postive terminal dont get any volts<br><br>the main problem is dont have any trailer brakes kinda bad with 15000# plus<br>looked for a fuse that is labeled something like that and nothing<br>any suggestions

 

Check the positive to a good body ground (probably need the ignition on). If you don't have positive or brakes (different lead), it is probably a bad ground.<br>Terry

 

those plugs get a lot of road cfrud in them you need to clean it out. I believe that in the power box under the hood that there is a fuse for the trailer setup that operates the plug

 

Sure sounds like you lost ground if nothing works. Put the negative lead on a good ground such as the frame (scratch a little to get thru the paint), turn on the lights and a turn signal, then try each of the pins. If you are showing 12v on any them, then you have a ground problem. Go back to the ground lead pin and try the others again. You are saying you have nothing, even brakes. That sure sounds like a ground to me.<br>Bob

 

When buddy and I went to Chicago and pulled somewhere between 5500 and 8000 (never hit a scale) of assorted parts on a car trailer we got ready to leave and had no trailer park lights. Truck had 'em and trailer had brake/turn. It was a 2001 2500.<br><br>He poked and prodded under the rear of the truck and cussed and swore. He opened the hood and poked around a little. I looked much harder and found a large fuse that was blown.<br><br>This leads me to believe you could find a similar situation. ???

 

found it under hood 40 amp fuse for trailer
