I am more or less at my wits end with this one. Lost. Start the game and it seems like the whole machine just kind of glitches out and goes, click...click...click then the ball release just twitches but doesn't stay energized long enough to release the ball. Unless, i unplug the motor to the cue stick shooter then it's fine. I have had the motor re-wound, coils changed, diodes checked, triacs changed and even put in new boards but still the problem remains. I have noticed after trying to release the ball the game somehow is triggering score and then act's as if the ball has drained then tries to release ball 2 then fails. Then ball three and the game ends. Its as if the batteries are low and there is not enough power to energize the coil but then there is the mysterious score triggering. And the fact that all the problems go away when i unplug the motor which is on a completely separate circuit. Lost.
