So I drove the truck sunday and it was fine, come out monday and the truck wont start. Do some poking and find out the main stud in the fusebox is loosey goosy and the bolt isnt tethered to anything anymore. I pull the fuse box and the plastic around the main stud is broken in two with a lot of burn mark around it. How hard is it to replace the entire fuse box? or can I just replace the piece where the main stud was?, From what I can tell there are no internal connectors inside the box to to release it from the rest of the wiring harness and thats a lot of wiring harness overall.

 

I believe it's a fusible link. I could be wrong.

 

Unfortunately it's not the fusible link. The stud and its retaining plastic have died, so I need to replace the box.

 

Its been a while, but I figured out a solution. I removed the little plastic holder that was cooked and used a short bolt with a washer and opted to not replace the entire fusebox. as an FYI, the fusebox is fully cabled across the front of the engine bay and includes the entire front lighting harness.
