Fusible link install Q's
Guys, here is what I plan to do. At the stater solenoid I plan to take the red 12 gauge wire, snip off the terminal and about 8" of the wire and solder in a 16 gauge fusible link with a 3/8" ring terminal and reinstall it onto the main power stud. Secondly, I plan to take the black 16 gauge wire (that is originally connected to the same ring terminal that the red one is), cut 8" off of it, solder on a 20 gauge fusible link and attach it's own 3'8" ring terminal and install it onto the main power stud next to the red 12 gauge wire. Of course I will also put a heavy duty shrink on each of the connections before I attach the ring terminals. I know there are others that I should consider, but I am taking John Hinkley's advice and starting with these two. The black wire runs to the ammeter.
I have seen where fusible links are sometimes installed in the middle of a longer run of wire within the harness like the red wire that runs to the horn relay, but with the wires terminating at the starter solenoid, it seems to make sense to put them there.
Is this the right way to approach this?

I know 60s era Mopar starter relays on the firewall used a fusible link between terminals. Since GMs is down on the solenoid at the starter (I assume like a C2) then it seems it would function the same way.
But I'm an electrical dummy so hoping someone else will come along to weigh in on the question.

Not meant to muddy the waters here. You’ve spent considerable time researching this project through.
Just to throw this into the mix:
On my ‘64 the center large wire ring terminal at the solenoid was removed, wire not cut. A separate pigtail, same gauge wire with separate ring terminals at either end and a 30 amp fuse/holder was installed in place of the former hard wired factory set up at the solenoid. The new and factory ring terminals were bolted together and insulated.
So so far the 30 amp fuse has blown several times. The first time was when the Pertronix was installed. The red wire got pinched to ground ever so slightly during installation.
Another time I shorted out the connection at the ballast resistor with a timing light connection. Some under hood wiring would have fried if the fuse had not been in place. How much overall wiring just this one fuse connection protects, I don’t know. Maybe one of the experienced electrical guy’s might chime in.

No one named Dan is a dummy here,Yes Mother Mopar used several links at starter relay and at firewall bulkhead connector.

Complicated I know, but I want to get it right. As mentioned before, when it comes to the electrical systems on these cars, I know very little.......but taking the time to learn it and do it right....I hope.
