There are three terminals. One on the flat base. The other two are located on the curved generator frame, one to the left (when looking at the flat base), and the other to the right.

I presume they are "armature", ''field'', and ''ground''. WHich is which?
 
The terminal on the endbell is "ARM".

One of the other terminals has NO insulation separating it from the "belly" of the stater. That is "GND".

The remaining terminal will be insulated from the belly (by a sleeve where it passes through, and by a fiber washer between the nut an washer on it and the "belly"). That is "FLD">
