I hooked up jb hunt trailer yesterday and IT jad a short in box where plug in pigtail. Blew my fuse. They fix trailer and replace fuse. Now half of Lights on trailer Are not working. They check pigtail connection at truck and no power to clearance Lights. I guess THAT short did something to my truck andi can't figure IT out. Any ideas
Trailer clearance lights all out

a seven way light plug tester would be a great thing to have to deal with this. Plug in to tractor seven way plug, see if all is good, plug into light cord see if all is good, then plug light cord with tester into trailer and see what happens. Will tell you in short order if problem is in tractor or trailer

Does it have a plug in tha back to plug light cord for a converter dolly? if so see if that one has power.

No plug in back

Pull the pig tail out of the socket on the truck and spread the pins. Make sure to turn the lights off first. Most of the time this is the problem. Be careful though because if you spread them too far the pins can break.
