So I don't have any power at my trailer plug. I've changed and checked all mini and long fuses under the dash and under the hood. I'm not sure which relay or other type fuse that I need to check/replace though.
I had power to the plug, then while wiring in a new plug on the camper I blew the fuses. I've changed a long one that was under the dash and a mini fuse but am stumped now. Any ideas would be great.

 

I believe there is a small fuse box under the hood fo the trailer, like one inch by 2 inch, it has a relay in there for turn signals.

 

I just need to figure out which one is which

 

ohm you wires to ground with power off. that will tell you if you got a short and shoot your terminals at the plug it should be somewhere around 12.8 with the truck off and around 13-14 with power on. i would check another trailer before you go through the hassle. trailers always have electrical problems. you also can always call your local ford dealer and they should hook you up with some kinda diagram

 

I've heard the same thing before, most guys end up finding out the trailer is the issue...

 

Well it's a learning experience for me. Fuse didn't look blown at all but apparently it was. Got it fixed and learned something new LOL. Thanx for the input guys, appreciate it much.
