Away from the machine at moment, so going by memory here.
Absolutely nothing happens when the ball drains at the moment. You can move the trough switch by hand and nothing happens either.
If I move the bonus unit under the playfield by hand, the bonus unit will reset when you press start for a new game. The bonus unit moves back and forth freely.
The ball is kicked into the the shooter lane at the start of a new game now, but after hitting the ball around and scoring points, nothing happens when the ball drains. It just stays on ball 1.
Will double check tonight.
