my machine has the modification to restore the ball locking on the dead world , in this setup if a ball is left on the dead world and i turn the machine on it will not play or activate until the crane and spinning dead world has unloaded the ball and when the ball enters the opto switches in the ball through it will operate normally , the ball through opto boards are notorious points of problems on this machine from what i've read , my boards were replaced by a third party brand long ago and i still get occasional issues with a single ball switch errors . i believe they have additional leds on them for indication for easy troubleshooting .
