12v electrical issue
We have a Jay Feather Ultra Lite, and I've suddenly developed an electric issue. Everything works fine on shore power, everything thing works fine on the battery, but as soon as I hook up to tow the fuse blows..... We just got a new to us F150 and had to have a 7 pin harness and electric brake system installed (professionally). Never had this problem when we pulled with our Mountaineer for 5 seasons. I've visually checked the wires on the trailer and can't find any shorts or bare spots. Could the tuck be shorting it out? Any help greatly appreciated, as I discovered this July 3 Rd as we were trying to leave for the week!
