2006 Peterbilt 379 Blowing fuses for high beam headlight.

I replaced all wiring at the hinges and new headlights. All wiring from there to the switches has been and it all came out good. I ended up taking it up to an electrician at Kenworth of Denton, Tx. Hopefully he can figure it out on monday.

 

All new wires in the hinged area.

 

I just discovered that when I push the left headlight back, ever so slightly, it blows the fuse. I am finally on to something now. I replaced the headlights with new ones after the issue was going on. It got to dark outside so tomorrow I am going to reroute the ground wires to a new location instead of them being grounded to the hinge. And I think that a hot wire is touching somewhere in that area. 2 things to look into tomorrow.

 

Yes. I just realized when I put that headlight on I put the cove washer on backwards. I then installed the right headlight and that is when I realized I put the left on backwards. I removed the left mounting nut and without taking the front face off I flipped tge cove washer and the bolt followed through the hole and I tightened everything back up. I am willing to bet that a wire inside the bucket is pinched from the head of the bolt. I did find the first issue, it was a hot lead marker wire that went bad and somebody replaced it with a new wire but did not isolate the old wire. The old wire decided to start working again and was shorting the new wire out. I isolated the old wire and the problem was fixed but I created another issue when I mashed the wire under the bolt head when installing the bucket.
