After dozens of hours of troubleshooting all the logic problems with this game came down to these trough switches. I discovered it by accident after I had to bend and create a new wire roll over metal switch that had worn and broken. One of these switches is shorted out. Which one is it? A constantly on switch can cause errors in game play. For this machine, this one error caused it to play a normal game up until multiball, then it would cycle through the balls and end the game without warning. Make sure all your switches are clean and adjusted, boys and girls.
