Test number one: Remove the wire from the F terminal mon gen. Start the tractor and set to 3/4 throttle. Use a 14 ga jumper to ground the F terminal. If it now charges, the gen is good and the cutout relay in the regulator is good. The ground of the regulator needs to be made absolute, or the regulator field control points windings, or resistors are toast. If no charge, with the F terminal still grounded, and tractor still running at 3/4 throttle, jump the Gen and Bat terminals across the regulator with a solid piece of insulated copper wire, 12 ga, or 10 gauge. Make a good connection. If charging now the regulator is toast. Disconnect the big jumper before shutting down. These tests completely eliminate the regulator one internal part at a time. Good Luck, JimN
