Fusible Links

[pagrunt]

They are in the fuse block. But a pair of these could be easily installed: https://www.amazon.com/dp/B000THTBZO/?tag=gbody-20

Years back I picked up a small fuse box out of either a Grand Am or Cavalier (can't remember which & before joining here) that house seven MAXI's to see about replacing the links but wasn't shure how to properly go about it. I even got a '97 C/K positive cable to run to the drivers side for mounting.

That is pretty much what I installed in the Monte. Basically you just have cut the fusible links and ring terminals, and put on new ring terminals. Then trace the wires back up the main harness and spice in your block or holder. If you are using the fuse block just connect a lead from the battery to the fuse block's main post.

Sounds easier than what was going on in my head about it. What is the rating for the fuses on a stock set up compairied to your Monte?

Yeah it wasn't so bad. The problem with the fusible links is it a bit of a ballpark exercise. Here's an example:

Basically the wires are about 4-6 feet long and are 12 to 10 ga wire so call it 40 to 60A. The blower/HVAC is going to have the biggest draw kicking that motor on.

That'll help to guide anyone in the right direction. Just going to have to figure out how many feet in that circuit. As for the HAVC I would like to give it it's own MAXI in that fuse block, the original wiring had melted conectors/burnt wires when I redid it 20 years ago.

In reality, they're only there to blow in the event of a short circuit (i.e.- crash). They don't even have to be at the starter; anywhere else (battery or alternator post) is fine as well.

Agreed. It is a silly place for them.

When I owned my 74 GP I was working on aircraft and I happened to borrow some of these to use. They are basically like a slow burning fuse that can be reset and they went up to 50 amps....

I'm not a fan of fusible links and did away with them. I also did away with the stock gang connection and separated all the wires into separately fused circuits.
Between doing that and needing some new wiring like going to dual electric radiator fans and headlight relays for my upgraded headlights, I installed a fuse block behind the overflow tank.
It's a Blue Sea Systems Safety Hub 150 and it's a very high quality piece and worked perfect for handling everything I needed.

The 4 bolt-down type fuses are MiDI-AMI type and I used time-delay for these. The 2 MIDI-AMI 40A fuses lead to the firewall connector and one leads to the ignition switch and the other to the main fuse panel. I upgraded the wire to 10GA from the stock 12GA for a little less voltage drop to the car's systems. The 2 MIDI-AMI 30A fuses are for my subwoofer amp and to power the radiator fans. You can also see that I used a 30A type 1 auto-reset breaker for the headlights. I also used 10GA wire from there to the relays.

I buy MIDI-AMI fuses from Waytek. By far the best selection and prices I've seen on these.

The power feed for the fuse block is a 4GA wire directly to the battery. The charging wire from the alternator goes directly to the battery also and is a 6GA. My battery is a dual terminal and I'm using both. The fuse block power feed and the charging wire go to the top post and the hot wire to the starter goes to the side post.

As I recall a fusible link can be no longer then 6"
