It seems as if I have two issues…
First, when the machine first turns on, the credits don’t count off and it won’t let any credits be added. It seems as if the machine gets stuck in the search cycle.
The other issue is, once I get it to allow me to play, it works fine, lets me run credits on, shoot the balls, keeps track of them, etc. When I hit the C button after shooting the 5 balls, it will start to search, then it arbitrarily light up other numbers without balls and give credit for any winners, including where the ghost numbers are at. Once it counts up all the credits, it will go back and play normal again until the C button is pressed again.
