After full restoration of my bally air aces the following problem occurs.
Everything works fine , but sometimes the score for player one does fully reset to zero.
You can hear the machine reset but not fully, there stays point om counter one, but machine stops en you can play again.
Its does not keep running as normal,when points are not on zero, but fully resets the machine .exept some point on counter one.
This problem does not occurs evertytime, but now and then.
Hope someone can help me
