-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. 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? Yes, you are 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 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 of the cut off goes to the large, left side of the Ford sol.
-Near side of the cut off goes to the top stud on the factory starter relay.
-Large, right side of Ford sol goes to the starter.
