I am thinking it is most likely a fusible link. Or perhaps just a broken wire. You might consider a new wire harness for the alternator to the battery.

To check just take a ohm meter and measure for continuity on both sides of the wire.

You can also check for a bad fusible link in the alt system by check for battery voltage on the back of the alternator output terminal, with the engine off.

Well, just about the only thing left is the simplest and cheapest....remove the major cables and wirebrush the ends along with where they attach.
