To start with, that wiring diagram you have is not right...like Royse said. It appears to be from a later model diesel. You do not have a fuel gauge, etc... Also you have a one terminal starter solenoid and the diagram has two. So get rid of that diagram you are using.
Do you have a shop manual for the NAA? Both my I&T and Ford shop manuals have good diagrams.
You still have a generator, so the diagrams should apply.
The wiring will not "fry" going from 6v to 12v. It is the same gauge wiring. You will "fry" stuff like bulbs and voltage regulators.
We have a bit of a crap shoot going on here. We know it ran, but not if it charged. We don't know if it is a 6v or 12v coil. So, I would pull off the generator, voltage regulator and coil. Take the genny to a starter shop or parts store and see if they can test it. See if you can get part numbers off the vr and coil and cross reference them to see if they are 6v or 12v.
Once you determine what you have, you can use the original wiring diagram to put things back together. For example, if the vr is 6v, replace it with a 12v unit. If the coil is 6v, you can replace it or put a resistor inline to knock the voltage down (if it were me, I would put a 12v coil on it).
From the pictures you provided, things look pretty straight forward. Just a matter of determining what parts are on the tractor.

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
