A villain mode is lit but shooting the scoop never starts it, even though the scoop switch shows in switch test and the ball is kicked out.

Villain mode never starts though the scoop switch tests fine: adjust the switch

Cause: The scoop switch closes when pushed by hand but a resting ball doesn't hold it closed long enough for the game to count it.

Checks

• Drop a ball into the scoop by hand in switch test and see if the switch stays closed while the ball sits there.

Fix

• Bend or adjust the scoop switch so the ball holds it firmly closed.

Systems

• Stern S.A.M.

Games

• X-Men
