Title: Ball Supersonic
Post by: vassemike on October 11, 2018, 09:27:09 AM

My Bally Supersonic (built about 1978) does not complete a game. It issues a ball maybe 2 or 3 times and then fails to eject it. If I leave the machine for an hour or so, it ejects a ball and only for a few then stops again!  Any help is greatly appreciated.

Does the switch in the outhole work ? Easy test is that at the end of the ball, the bonus counts down and then it should kick the ball out. You can check the wires on the coil, and then the connectors on the Solenoid Driver board. Do you have the schematic ?


Sounds like something simple - connectors is my best bet.
