Ammeter Battery overcharge

Thanks Ben, I appreciate your help and understand there is only so much that can be achieved thru the net and hopefully "osmosis". It is still NO start, as I have cut ammeter red and black wires at DASH side of bulkhead. I have NOT pulled the cluster yet, thats one of the next steps. I just hope that the RED and BLACK wires I cut were the ones for the ammeter. Im on my 2nd cup of coffee and about to dig into this more.
***BUT*** looking at Schematic from PLYMOUTH FSM, it doesnt list BARRACUDA specifically, but shows VALIANT models which I was following. Comparing that schematic to another FACTORY one that I got saved to my computer shows different locations for the RED wire from Ammeter. See pics, I took one of the FSM Valiant model and one of the BARRACUDA that is a factory printout(pencil in pic)
BOTH show Red ammeter wire going to different locations in Bulkhead. Factory hardcopy shows Red ammeter wire(Circuit A1) going to "Z" hole in bulkhead.
NOW look at pic of BARRACUDA printout. It shows the Red ammeter the SAME circuit "A1", BUT it leads to "J" hole in bulkhead, located in the middle part of blukhead??
I know 67 being the 1st year of 2nd gen barracudas that there would be errors(dad n I discovered 4 years ago an updated schematic for AC as Del posted a different FSM one that he had)
Hopefully now that Ive got a decent sleep I can maybe make sense of it. LOL
It doesnt make sense that the car ran great for 4 years with no elec issues and the harness be buggered up. When I look at the 2 engine compartment M & H harness they look brand new as in UNALTERED Macgyvered etc.
See pics
