Ok gang, when we drop a coin into the slot the machine counts up 6 balls most of the time. Occasionally it will do 5 like it should but most times its 6.
Any suggestions? Not having studied the diagram in detail but I would imagine we get 5 pulses off of the A level of the score motor to advance the ball count unit...but an extra?
Game is just coming back to life after a repaint and siting idle for 10+ years.. One of the last issues.
