I'm a new member and just found your Web page. I hoping to find some help with my trucks that we use in our construction business.
I have 3 1998 F800 trucks we use in our business. I have one that has melted the fuse box on a couple of circuits and need to rewire and find the high amp draw causing the problem.
I'm hoping to find someone that has a schematic for this truck that they could share online or suggest where I might find one a manual.

Any help would be great.

Thanks in advance!!

 

Moved to this forum.

 

Scroll to page 33 (top or side of the page, not the pages on the actual item) for very little help:

Was '99 nearly the same?
