Fusible link. Usually a short section of wire about 12 gauge (much smaller than the battery cable itself) that provides main power to to the car. It could be bolted to the solenoid along with the positive cable from the battery. The "fusible link" part of the wire is much smaller for a few inches. This part is the "fuse". It is meant to "burn out" before the the "over load" frys everything downstream from it. Finding the dang fusible link, assuming you have one, can be frustrating. Trace the positive cable from the battery, to the solenoid, find the smaller main feed wire from the solenoid and "track it down".

If you have a Chevy motor, the solenoid is on the starter and none of this applies so "go fish", lol.
