Alternator wiring

Car is not charging. Removed alternator and found fusible link wire burnt in half. Repaired but still no connection to battery. Here's the weird part: the fusible link goes up the harness to a relay (red with black tracer that feeds into an orange on the other side of the relay which goes to ground tested with meter). Can't find any evidence of another link to the red wire on the starter solenoid from the B+ terminal on the alternator-both on the alternator and the starter sol. I've looked everywhere for a service wiring diagram but can't find one for this model and year. Common sense says to create a solid connection from the B+ alternator terminal to the always hot side of the starter sol. But I don't want to reroute power if it wasn't going there in the first place.
