Fusible links

Why do the OEM's use fusible links and not replaceable fuses in the main power lines and alternator to battery line? Why is there a fusible link between the alternator and the starter solenoid? If half the wire burns up as a fusable link, why not just use 8 awg for the whole 12" wire? It would be the fusable link since it's connecting to the 4 awg or larger starter cable?

Re: Fusible links

Went to the auto parts store looking for wire. Nobody in this town has 8 gauge wire for the alternator. Found a 175 amp alternator fuse ($5.00) that would bolt onto the lug of the alternator or solenoid. I am considering that option along with some 4 gauge for the cabling. Don't need that gauge, but there doesn't seem to be anything in between around here, although I am sure I have not as yet exhausted all local sources.

Re: Fusible links

1. The wire's under constant current draw.
2. A fuse has a cycle life, so many hits and it blows...
3. Even a so called "slow-blow" fuse.
4. Fusible links are more robust,
5. They just plain last longer...
6. But can be a PITA to repair,
7. Because there's not visual indication when they go bad.

Re: Fusible links

And they use a short piece of fusible link instead of running it the whole length so that if it burns up it limits the damage to a small section of the harness instead of destroying the whole thing.

Hah! You should have seen my fusible links after my now disco'd electric choke wire grounded out! Well, I *thought* it was taped well!

Re: Fusible links

1. Bishiop, "go bad" is a lot different than,
2. Being Murdered by a direct short!
3. Then they scream their little heads off...
4. It's similar to waking up dead someday...
5. Or being Father Isaac Jogues.
