I have a 2007 Diesel and I pull a trailer for my race car. I know there is a circuit to charge the battery but I keep blowing the fuse in the truck. Any idea what can be wrong or what do I need to look for?


Thanks Tore

 

Look here: https://www.ford-trucks.com/forums/5...g-diagram.html

It's the wiring diagram for the 7-way plug. You prob have corrosion inside the connector on the truck....or a short in the trailer somewhere. Use a 12v test light or a multimeter.
