Fusible link rating
 

Does anyone know the rating of the fusible link in the
alternator-to-positive terminal battery wire? Would it be unwise to remove
this link and replace with straight 4-gauge wire? FSM indicates a fusible
link but no rating. It's insulated in green and looks like the diameter of a
6- or 8-gauge wire.

Re: Fusible link rating
 

Please don't do that. If something shorts out, the fusible link is there to
proteect the rest of the wiring. I have seen mods where the fusible link is
replaced with an inline fuse, but to do that you would need the amperage
rating of the original link. Some vehicles have the amperage rating is
printed right on the link.

Re: Fusible link rating
 

Gotcha. There were no markings on the link that I could see. I had to
replace the wire to the alternator because the alternator end had melted off
during heavy winching, and the remaining wire was too short. I undid the
splice between the link and the old wire and just spliced the new wire to
the link. Had to replace the alternator as well, got a Mean Green. I would
assume a fuse or fusible link rated at the max output of the alternator
would provide sufficient protection, any reason not to agree?

Re: Fusible link rating
 

The red alternator wire is 10 gauge and is protected by a 14 gauge fuse
link.

Normally a fuse link is 2 sizes smaller than the circuit it protects.

The fat size is just soft rubber insulation that won't melt like plastic
when the link gets hot.

You can buy fuse link wire in bulk to replace one if needed. Be aware
that you have to use crimp connectors on the ends and it needs to be the
same length as the stock one or about 8" long. Solder will ruin the
thermal properties of the link.

If you replace a fuse link with regular wire or with heavier wire, you
will cause a fire to start when whatever blew the first link goes nuts
again.
