Hi! I have a Gottlieb Operation Thunder pin with a vari-target that doesn't score. Mechanically, the switch is fine. Goes smoothly through the full range of motion. Both blades make proper contact through the entire range of motion and all contact surfaces are clean. When the ball drains, the coil fires and the switch returns to it's starting position. I pulled the plug from the back of the board and all pins are reading 4.4 volts except for the far right pin which reads 0.0v. I do not have a manual so I don't know if that is correct or not. Any Gottlieb gurus out there have any ideas? Thanks!
