I'm a proud owner of a TSPP since yesterday. But i have (a little) problem with it. Sometimes when a shoot the garage, the machine is putting balls in the shooter lane without shooting them. And this happen when a don't start a mode Any suggestions?

It's holding the ball for a short moment before it goes to the upper playfield, but no ball search. There are 5 balls installed.

Just tested some more. As long as the ball is in the upper left VUK, it's putting balls in the shooterlane. At the moment when the ball is shot in the livingroom, it stops.

If i see it right, there not in the same row or column.

If i test the upper left vuk switch, the 5 ball stacking opto wil register also. I can't see anaything strange with the cables. And if i test the 5 ball stacking opto the left vuk does not register.

I found the problem. It was a bad connector on the optoboard. Fixed it!
