Fuse for marker lights melted

Is this problem on the 94 t800 ya mentioned in another thread?

 

If youre in a kw, the real fix is to more or less redo all the wiring in the fuse/relay panel/replace. its not just that its loose, water runs down the panel corroding things. Markers and headlights tend to go first.

Its not a hard or particularly difficult job, but its time consuming and needs meticulous attention to detail

 

Kenworth sells a kit to replace the melted section in the fuse panel.
Its a bit of a pain to do but certainly doable.

 

Ok you’ll have the same fuse box I do. I had a similar problem with mine and found that the plastic piece that holds the pins in place broke. It’s been several years ago but I think what I done was after removing the box and the panel from the box was push the pins back in and put a dab of silicone on the keeper (I think it was yellow) and reinstalled it then let it cure before I reinstalled the fuse. I haven’t had any problems with it since.

This is what it looks like when ya get it out, it’s not all that bad to do

 

Get yourself some more foam weatherstripping from the hardware store to reseal it to the cab as well.
