The correct generator for a 600/800 is the 3-Wire/2-Brush B-Circuit Designed 20 AMP output style. "G" is always GROUND. "F" is always FIELD, and "A" is ARMATURE. G and F terminals are on the barrel, A is on the back end plate. F has an insulator behind the stud. The correct Voltage Regulator is p/n FAG-10505-A. Wiring diagram in OEM Operator's Manual. Schematic diagram is in the I&T FO-20 Manual.
