Fusible link ????

So it's analogous to the wire over my index finger? There's no fusible link in that line.

Still, when compared to a OEM cable, it looks a little thin. Could be insulation, but the crimped end looks like there's more wire on the factory cable.

There's only the amount of current going through the wire to energize the relay, but a 10 gauge line compared to one with a 16 gauge fusible link is considerably stouter.

*Edit - but there should be a fusible link in the ammeter bypass wire.
