Farmall A wiring conflicts

One version was once posted here by 'Old Red' showing his photographed schematic. It shows the Field on the generator to the F on the vr, AND another connection from the Field on the generator back to the ammeter. The lights come off of the Load terminal on the vr. Then a connection from generator 'A' to vr 'Bat'.

In contrast is the schematic host by Bob Melville
[http://albums.photo.epson.com/j/ViewPhoto?u=
4001561&a=30065733&p=60246204] that is quite different. Is the Bob M schematic for a cut-out application only and not a voltage regulator?

Is there a schematic around for a 6V pos-ground system with a vr?

Thank you.

You need the diagram for a voltage regulator.... punch below.
