Battery in Trunk Wiring That Exceeds NHRA Requirements

My electrical ignorance continues. I don't mind, though. Maybe this thread will help someone else.

I removed the yellow wire from the blue field wire (leaving the field connected), and also removed the factory charge wire from the alt. Then I connected the yellow wire to the charge post on the alt.

It starts, everything works (lights, horn, etc.), and everything shuts off with the cut off. However, the battery is not being charged.

The disconnected factory charge wire has power when the cutoff switch is "on", but not when it is "off". (key off)

Wud I do? And wud I do now? :(

EDIT: by the way, this is a 74 with seatbelt interlock and I’ve also done a Mad Electrical ammeter bypass, if that’s relevant.
