Shadow, The Bally, 1994

Trying to help a friend troubleshoot his Shadow before I head up there. As I understand it, The Battlefield left/right motor works fine in the T16 Mini Battlefield test, but the flippers switches do not actuate the motor left or right in game play. Both opto boards were swapped out with no change (not surprising to me as this should have caused it to malfunction in test as well).

I'm stumped. Unless the setting 31 is set to disabled (which shouldn't allow the ball to get up there to begin with), I'm trying to think of a scenario in which the CPU control of the left/right movement of the kicker would work, but neither flipper button would work in game play.

Any ideas?

I can’t help, but post the question in the shadow owners thread. Hopefully someone can help find a quick solution.

I just tested on my Shadow. With the Battlefield off (setting 31). the flippers do not move the battlefield paddle. The battlefield drop target still gets knocked down by the ball and then will pop back up. So it is possible for a ball to sneak past the drop target before it resets and the ball gets ejected to the battlefield.

What may be happening is an issue with the drop target switch in conjunction with Setting 31 turned off. The drop target might always be down if the switch is out of adjustment, allowing the ball to always reach the disabled battlefield. See if the game properly resets the drop target when powering on and if the target remains up.

If the battlefield is not disabled, then it could be the drop target not working and allowing the ball to reach the battlefield when the battlefield is not lit.
