Data East Tommy needs help! The problem is so weird that it is difficult to even explain it...
Tommy is in great shape, everything works perfectly. Even blinders and mirror. In diagnostic mode every coil fires correctly, shooter/kicker assy work great, all switches open and close. But...
When the ball drains, Tommy quickly fires all coils in sequence, like when looking for a ball. Then it ejects the next ball. That is not normal, but I could live with that.
But when the mirror gets lowered and Tommy is getting ready for multiball, machine freaks out. Tommy starts firing coils randomly. All 6 balls are ejected one after another. Then Tommy loses count of balls. And the coil in 6-ball assy (coil that kicks balls upwards) is firing weakly in the rhythm of music.
Where should I start?
