So here is what I see around that area.
1. black "fat wire" one red going into one side 2 out of the other. (same thing that is comming right off the starter.
2. Some yellow wire connections between that bracket and the black thing.
Also the black thing is marked 16. Is that the fusible link?
Looks like someone has been in there before. Your fusible link is is the part of the wire where that yellow crimp connector is, above the black factory splice. Then the other link is the red section right next to it. When mine went, I cut out the bad sections and spliced in the new links. I think I had about 1/2 inch of useable wire above that black splice.
On the diagram that Fordum posted, you can see the junction block on the right side. To the left of it, it has the fusible links then 4 Red 3 wires and a Red 2 wire from there. The Red 2 wire goes to your Battery and should show voltage before the black splice. The two red wires going into the black splice, one comes from the Alt and the other I don't remember (Fordum's diagram is cut off). Again, you should check for voltage on that side. Then check directly at that junction block. If no voltage is at the block, then you have narrowed your damaged section down.
