Duster fusible link wiring problem

Here's what I see in your photo.
Something, probably a link? could be a hacked wire, is hanging on by a couple of strands at the spliced junction. I suspect this link/wire connects to the alternator output stud.
Of the two links, each looks to have a different color than the other.
They are both spliced to a heavy black wire, probably 10 gage. We know this wire eventually connects back to the battery positive terminal.

The 10 or 12 gage red wire attached to the relay stud must eventually connect back to the battery positive terminal. It may do this by a connection or splice with the heavy black wire. (This red wire carries current for the starter relay to power the starter's solenoid.)
