The “When Lit” indications on targets informs the player that the machine will not register a hit on a target when the motor is already turning and scoring a previous hit…. the targets’ lights should go out during this period.

As an example, if you hit a “50 Yards and 5000” top rollover, drop onto the pop bumper and get knocked through the “50 Yards and 5000” side rollover, the machine will start the motor in response to the first rollover and begin counting up your yards and points. During this process, additional scoring is disabled. The machine (likely) will not register the second or third score while still in the act of scoring the first.

For Gridiron specifically, while the motor is turning - pops, rollovers, 1 point targets, 100 point targets, the spinner and kicking rubber switches are ignored, or, more accurately, are ignored if your Motor 1C switches are adjusted correctly.

Gridiron is unique in that there is one exception to this rule - the outlane Touchdown. The touchdown will be queued and scored appropriately even if the motor was turning as the touchdown rollover was hit.
