Ok, heres an update I got all 3 boards hooked up but i'm still having problems. When I turn the crane on the claw will move to the home position and the counter and seconds will both be on zero but it will not reconize anyone coins or bills that I put into it. So after that I tried to do a self test by turning dip switch 8 on and all the others off then 1-4 on but nothing happened. After that I pulled the wiring harness that goes to the buttons and coin mech from the relay board and it starting cycling the self tests so then I turned dip switch 8 off and tried it pulling off the wiring harness again and it started adding plays to the play counter but I still could not play the game. Also there is a small green wire coming off of the claw wiring harness that im not sure where it goes. Help!!!!!!
