Blown Fusible link

The large 12 gauge wire coming from the starter relay laid up against the exhaust manifold. Half the wire melted and the fusible link vaporized.

Side-of-the-road wiring repair took approx 2 hours.

Here's the fusible link. All that's left is the ring terminal and insulation.

Think I found a source for fusible links. Amazon carries all types of them.

I've never had a problem finding rolls of fusible link at NAPA.

Is there any reason to not go with an inline fuse over the fuseable link? It's easier to replace a fuse than a burned out wire. That's what I've done when I had a fuseable link go.

You could use a fuse or a circuit breaker for that matter. I'd think that ideally the fuse used should have a "slow blow" character and not go open in case of a momentary accidental short circuit.

Fusible links are crimped and soldered into the harness, avoiding the failure point introduced by the mechanical connection of a fuse or breaker. Not perfect, but more reliable than a spring clip or nut. Fuses can fail unexpectedly and are subject to corrosion.

Really, the fusible link is installed where it's only useful in case of a catastrophic short circuit, like you might have in a wreck. It should not need to be easily serviced. If you are blowing them regularly, there is something radically wrong with your wiring or how you use it.
