alternator wires

You could also run a fuse. A lot of alternator upgraded wiring kits from painless etc. come with a inline fuse and holder.

Napa sells a fuse holder #BK7821143 that you could get a 60 amp fuse for. Much safer than a fusible link.

Ron Francis wiring Does not recommend fusible links and can be a source of fire.

Modern cars have all gone to fuses for protection.

X2 on using a fuse instead of a fusible link. The factory used links because they were cheap. By the mid 1980's they finally came around and started using fuses. Fusible links are kind of maybe they will or maybe they won't devices.

I would bet a #12 gauge link would not melt on a 50 amp alternator output unless the alternator totally shorted to ground and the battery was being dumped back through it. Chrysler used a #16 gauge link on 45 amp alternator circuits and even they didn't always melt in time to save the wiring.
