I recently bought a "shopped" Hay Ride. After many hours of freeing frozen steppers and replacing many failed Bally sockets, I'm left with one issue.

After lighting BALL the center mushroom will light (STAR). Hitting the star advances the lit pumpkins, but does not award the added ball.

Added balls are awarded for all other achievements (lighting BALLY lower left exit rollover and high score thresholds).

The schematic only references the star in the light circuit. But it appears that the mushroom circuits B-A-L-L is the key. Since lighting BALLY lights the special rollover and awards added balls, Im focused on a condition not being met in the B-A-L-L circuit.

Any help would be GREAT
