I've taken the picture below in the hopes that someone can tell me what the correct operation of these switches whIch load the ball onto the shooter lane is suppose to be.
When the ball drains its immediately kicked up the the second switch which then immediately loads the ball into the shooter lane. I expect that this operation is correct except for the ball being loaded into the shooter lane while there's already a ball in play. Can anyone tell me what tells the machine that a ball is already in play?
