68 Barracuda Formula S 340 car Charging

Bad picture not showing all the terminals. Assuming that you have the original single wire field. You have one smaller wire going to the field (actually a brush), and on the opposite side the brush is grounded to the case (no wire). While running, go to your VR with a jump wire and jump it's two terminals, bypassing it, and forcing maximum output. How much is it charging now?
