Battery in Trunk Wiring That Exceeds NHRA Requirements

I'm back. I just did the battery in trunk, using this diagram. The only thing I did differently is I connected the pos battery to the left side of the continuous duty relay (CD), instead of using the left side of the Ford solenoid (FS), because I already had a cable that length.

It starts, runs, everything works and the battery is being charged. However, when I throw the master disconnect (MD), only the alternator stops working (system goes to battery voltage). It runs and everything works, as if I didn't throw the switch.

The wire from the small terminal on the left side of the FS goes to the factory starter relay (FSR), in the "middle" so to speak, where the square gizmo helps retain it. (Sorry for the non-terminology)

The wire to "switched power source" is going to an auxiliary fuse box that gets voltage when the key is on. (I used the wire between the relay and the aux fuse box.)

I don't have a one wire alternator. Mine is the original '74. I connected the wire from the right side of the CD to the blue field wire, which I picked up near the resistor that it's connected to. I checked continuity from there to the alternator to be sure it was the correct one.

This picture shows what I did. The cable on the right side of the FS goes to the starter. The cable coming off the bottom, left side of the FS, goes to far side of the MD (marked "ON" on the outside of the car). The cable coming off the near side of the MD (marked "OFF" on the outside of the car), goes to the large lug on the FSR, still in it's factory location. I didn't know what gauge it should be, so I went with the same 1/0 I used everywhere else.

The blue wire on the CD goes to the switched power source.

The wire on the right side of the CD goes to the field wire.

I know I need to fuse everything. I did it bass ackwards. I was as careful as I could be as I hooked up the battery, looking for arcs, etc.
I'll ask about how to protect everything after I get it to turn off at the switch.

What am I missing?
