How did this happen?

check to make sure your clearance lights, brake and turn signals all work, and yes, you can run it. Maybe buy a roll of electrical tape in the truckstop, unless you carry one like I do, and wrap it up. if anyone asks what happened, you have no idea, you just taped it up so it for sure wouldn’t short out

 

It looks like your electrical pigtail rubbed on a tire or the road.

 

Those are $50. If you're worried about being hasseled by your company just buy one, put it on, and keep the truck rolling. You don't need to call the boss for every little thing out on the road.

 

Looks like ur turn signal ain't gonna work. Forget which direction green is, either left or right..just buy a new one. Better yet carry a spare with you.

Also be careful with ur lines, ur red airline looks like it got snagged as well. Probably turning to sharp and it got pinched... if u run into a knuckledragger dot man they will write u up for chaffed line

 

Yeah, I've done that on sharp turns.

 

If you get pulled in for an inspection you will get put OOS for that.
Also, you've got a bare wire showing. You need to fix it ASAP.

 

Won’t get put OOS if it’s taped. As it is, yeah, probably

 

It’s not sabotage you turn tight and the cord got caught on something .Just buy another

 

I guessing you made a sharp right turn and the glad hands are plumbed on the drivers side of the trailer? One thing I've learned is to make left turns when it's going to be tight, reduces the chance of over stretching or hanging up the airlines or pig tail.
