Blown Fusible link

[Driftwood]

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.

Any parts store has fusible links.

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.
