Wiring Alternator to Starter

[1968_K20_4x4]

Hello All, quick question about alternator wiring. Going through the wiring of my '68 K20 with a 307. The P.O. installed an SI alternator in the truck and ran a red wire from the "Bat" terminal of the alternator to the positive terminal of the starter motor (connected to where the positive battery cable connects to the starter). Here is my question: Should I install a fusable link to this wire to protect the circuit? Should the fusable link be 16guage?

They then connected the same red wire to the no. 2 post on the alternator and ran a tan wire from no.1 on the alt to the fuse block. The old voltage regulator unit has been completely bypassed.

Edit: I have seen other diagrams where this wire is tied in to the main red wire that comes off the battery and runs to the fuse block. However my alternator is on the passenger side and I would like to keep it wired up the way it is for cosmetic reasons. Just want to make sure it's wired in properly



Thanks for the help
