fusible links
Just changed the alternator and noticed that the wires connecting my fusible links are very brittle. One even broke, so I soldered it and covered in in heat shrink tube, but this is a band aid. Does anyone know the rating of these links so that I can change them to modern fuses?
Also would having a new higher output alternator require a larger amp fusible link or fuse?
The tag on my new alternator rates it at 87-116amps.
Thanks

You should be fine, soldering with shrink wrap is good fix....I assume the link was copper and not steel, in which case it should have been crimped with a QUALITY thick walled wire splice and crimping tool....
then shrink wrapped....there is no need to change a thing with the fuse links due to higher alt amps outputs....just take your power requirement off the alternator directly, or the horn relay/distribution point on the fender....but if you go there you need at least an #8 wire to the alternator from there....things like fans go to the alt directly, chassis ground is fine for fans on the - feed....amps should go the same route, off the alt, NOT the battery....charging reasons...

8 ga from alt to junction block is okay, if you have increased the loads along with the alternator rating, use a 12 ga fusible link in that wire.
generally, you don't want to replace a fusible link with a modern fuse. you will create more potential for problems. if needed, replace the fusible link with a new fusible link. i understand that the real issue is with the wire connected to the link. but these are the wires that typically carry higher amps and new links are readily available.
