I thought I had this game working 100% but low and behold it slapped me in the face and said whoa boy. The game has 5 roll over up top. When you go through lane 1 through 5 it lights its corresponding number near the spin wheel. The game adds a ball if you hit the number on the spin wheel that is lit from the lanes. It is also supposed to add a ball if you lite all 5 lanes. However it adds max balls and runs it up to 10 when all 5 are lit. What would make it do this? is it a separate switch from the single number on the spin wheel? My only guess without schematics and more time before I had to leave was a different switch somewhere that is stuck. You would think a machine gun is being fired when it awards 9 balls that fast lol.
