Battery in Trunk Wiring That Exceeds NHRA Requirements

I've tried 3 times to repost the same picture, because nothing has changed in the back. (This computer is driving me nuts!) I did what I think you said to do:
-I removed the yellow wire from the blue field at the front. It was tapped into the blue field, which was still connected to the alt.
-I disconnected the factory charge wire from the alt.
-I connected the yellow wire to the alt charge stud. What you said about a dedicated charge cable to the alt charge stud JUST SANK IN! That yellow wire isn't heavy enough.
With all respect, I'm starting to think something is missing from your schematic, but I'm probably missing something. In your photo, there is a cable between the right side of the CD and the right side of the Ford sol. In your schematic, there is nothing there. Am I wrong?
As info: the blue wire goes to switched power source, and the black wire goes to the center of the factory starter relay (the original wire that was on the center stud went to the starter.)
Regarding the 1/0 cables that can't be readily seen in the photo:
-Far side ("ON") of the cut off goes to the left, large stud on the Ford sol.
-Near side ("OFF") of the cut off goes to the top stud on the Ford sol.
-The large, right side, Ford sol goes to the starter. (And I put a jumper across the two studs on the starter.)
