    was thinking about replacing the the fusible links on my truck (87 k5) with fuses when i do the battery relocation/cable upgrades. ive never really seen a wiring diagram or really even paid that much attention to the wires on my truck. im assuming that theres a couple coming from the alternator and a couple coming from the starter. any ideas as to what size fuses to use?

    I burned my fusible link when my 150amp alternator bit the big one. I replaced it with a 60amp Maxi-fuse and haven't had any trouble.

    This isn't a great idea. Each wire that is protected by a fusible link can only carry a certain amount of current, perhaps 30 amps max. Hooking multiple circuits into a mongo single fuse doesn't provide protection for the individual wires. A short in one of the wires could draw more current than the wire can handle, but less current than it takes to blow the fuse. That's a recipe for an electrical fire. :eek1:

    The correct way to wire it would be to have smaller fuses replace each of the individual fusible links.
