Hi John
Did you recognize the difference at the Ammeter drawing between the drawing out of the Ford Manual and the other from the Autolite Manual?
On the Autolite is a connection between Alternator-O, Battery-+ and Regulator-I.
The rest seems to be identical and it seems to me the source for this drawings was the same.
