Just a quick question

Hey guys!
I'm trying to do some research for my uncle on his 85 ram. We're thinking the wire on the positive cable with the quick disconnect is a fusiable link, but it also runs to the battery. His was cooked on the truck. Is there a replacement one or is there a way to update that wire. I know this will be an interesting one to decifer.
Let me know, thanks in advance
Cam W.
