I did not purposely disconnect wires. I failed to hook it up on initial hookup.
I found the problem. Jayco clamps the brake wires to the bottom of the frame above the leaf spring. When the trailer bottoms out the leaf spring shackle is pinching and subsequently crushed the wires, causing them to short. I fixed them and called my dealer and told them the Jayco design is terrible, the wires should have been mounted on the inside of the frame and then down to the hub. I am taking it to the dealership on Monday to have the wire length replaced as it is crushed in multiple places and have them mount the wires a different way.
I cannot believe Jayco mounted these wires this way.
