Trailer Wiring Question.

[Joe Bob]

Seven pin trailer plug on the rear of the bumper. The "+" pin, upper right at one o'clock does not have any power. Everythung else is fine. + is for charging the battery of the tent trailer.

 

Is there a fuse somewhere that needs replacement or a relay that needs to replace a dummy plug? If so, where is it located?

 

Tow vehicle is a 2003 Yukon 2500 with Quadsteer.

pop the hood, open the fuse box, if you look there will be a red dummy plug in one of the fuses. pop a fuse in there and you're good to go!

Yup, got the red B+ plug in there. Is there a part number for the 40 amp fuse? I need to travel a bit as I'm in the boonies. Knowing the part is available is better than driving 20 miles and not finding it.

 

I assume this fuse will energize the "+" circuit on my wiring loom?

Any parts store should have this fuse.

I pulled the 30 amp from stud 2, got power on that circuit. So I'm happy.
