Circuit Breaker vs Maxi Fuse
I'm not home right now to scan my revision drawing, but on my 85 d150 the wiring was a horrible mess when I got it/to the point of wondering how it hadn't burned to the ground before I "rescued" it from the PO. Bad enough, that it was not only easier, but much safer, to start with a new harness from a junkyard refugee /to repair the damage done by previous owner "interference". I mean c'mon man...
The big hot wire off of the alternator changed gauge and color 3x in the length of the/6 valve cover.just twisted and crudely taped splices 2-3 fusibles had fried and were " fixed" the same way.
One of the repairs was hanging less than 1/2" above the gas feed line to the carb with bare exposed strands. It's a wonder if didn't arc out and burn.
My solution included (dare I say it,) including a Ford part in my repairs.i wired in an under hood fuse box (had all Maxi fuses in it) and I wired every original circuit that originally was "protected"by a fusible link thru a Maxi fuse. I also added a 2nd 10 ga (same as oem on my truck) charge wire direct from the alternator "hot" terminal to the battery thru one of the 60a fuse positions, in that fuse box.
I forgot to say that the fuse box I used was from a 90-92 ish ranger.
I consulted the Littelfuse company while I was at it and they actually sent me a bulletin telling about the development of the Maxi fuse and how it was meant as a replacement for fusible links.its on an old phone, not this one /so no more fusible links for me.
Im camping right now, actually not that far from
@my68barracuda for the next few days. If anyone is interested in doing as I did, once I'm home, I can dig it out and post.
