Assuming that's the - terminal, you lost a ground somewhere that wants much more current than the burnt wire could supply so it fried. I'd be looking at the battery to engine ground.
As stated above, the ground goes to the engine, then the cab, then the frame via ground straps. The + side has a low current wire from the battery to a junction block on the fender.
BTW, the battery to a junction block should be or have a fusible link. This prevents the dreaded carbecue scenario. Guess how I know this.
