I don't think B is connected to D for some reason.
I would not worry about your voltage regulation. Since the battery is not connected to the gen, there is no current flowing through the regulation circuit. If you look at it, they just use resistors. No current flow through a resistor means no voltage drop, so the regulator is not going to regulate until you get the juice flowing through it.
P.S. I see the regulation circuit flows current from the field circuit. So while that regulates the output of the gen, I still would not worry about the regulation until I got the other problem fixed first.
Well that's the thing is trying to solve what the problem is. I think its in the regulator itself. All the circuits are connected and they are showing voltage from the generator to the regulator. I tried measuring current with my old Matco inductive analog amp meter and it was hard to tell but it looks like it wasn't but 3 or so amps coming out of that wire. I cant remember though if it was still outputting 24V or if I had already brought it back to idle where it was registering 8V. That's the problem with working on this then coming to work on Monday and screwing with cars working on them for two days.
Is your regulator a low profile modern version(electronic)? Or is it the older taller style that might have the relays in it. If it's the old style you could take it apart and see what is going on. Once you get it straight in your head what relay does what, you could activate the one relay manually and see what happens. If the cover has some rivets in it, you can easily drill them out and put small bolt and nuts on it to put it back together later.
I know you want to get it fixed, but if all else fails, you can put manual switches on it to make it charge. Just simulate what the regulator does. I have seen people use a regular relay to connect the armature to the battery once the key is on, and then they have another two position switch, one for low charge and one for high charge. If you run the tractor on a regular basis for at least an hour or so, probably the low charge resistor hooked to a switch would be all you need.
Sometimes rigging stuff like this gives you a eureka moment and you figure out what the original problem was. At least it takes the pressure off for awhile to get it fixed. What would really be a puzzler is if you did rig the switches and it still does not charge. That would be a reason to go back in the house and think about it for awhile. Been there, done that.

Its a conventional relay coil regulator. I know cause when I installed it initially the charge light wouldn't go out. I had the case off and the cut out relay I would manually close and it would go out the light would work fine. Shut the tractor off and restart it the light wouldn't go off.
