Help with no power??
So here goes.
Jumping the relay only provides power to the starter. So the battery has juice and the relay works but that's not the issue.
The issue is there is no power going to the power distribution splice.
That's the welded wire splice joining the power sources (alternator and battery) to the power feeds for everything but the starter.
So far from your description the fusible link will be the thing to check.
If it has failed, it most likely failed for one of two reasons.
1. There is a short to ground in the power feeds.
2. It slowly deteriorated due to repeated moderately excessive loads, which could be a weakly connected short, or some other condition that caused repeated high battery discharge and/or high battery charge rates over periods of time.
If there is a fuse instead of a fusible link, that won't handle the charging loads right after start.
Not all fusible links used the flat connector. At some point a round connector that looks like a fuse holder came into use.
IF the fusible link has gone poof! (wire inside burned up), then check for short to grounds before proceeding.
Do this by disconnecting the battery, and use an ohm meter or continuity checker. There should be no continuity between the mains feed wires and ground. Easy place to check the alternator stud ring terminal.
I think everyone was sleepy last night. LOL
