Welcome, not sure I understand your post? One of the wires off positive battery post, should go to junction block, just follow the wire. The fusible links are at the junction block. You can take negative battery loose, so the junction block is dead.

If I don't know which fusible link is which, I test them all. Just get past the link, use a testlite start checking.
If you want to know which circuit it is, take the suspect circuit loose at both ends, make sure there is no voltage, do a resistance test. See if there is continuity between the ends.
