It's this circuit but the 6800 is 220 instead and replace the regular solenoid with the smc solenoid in the angel also stock charging switch now used as off/on
i just used a 2k2 timmy board with a 9v all fitting in the grip, i had to mill the fram out some but it worked. i also enjoyed using the battery chamber to route wires for eyes. i think if i had used a universal t board i could have put that inside the battery chamber and used just the grip for the 9v.
