Hi. Purchased my first pin, a GB Pro. Loving it. I have a couple questions about odd behaviour. Sfw is v1.13.

I often select the Skill Shot to be the Award Scene. When I hit it, it asks ESP or Don't Cross The Streams, I select cross the streams, it then kicks the ball out to start play again (sometimes also starting Scoleri Brothers), then 1-2s later the playfield goes dark, flippers lose power, ball drains and the cross the stream game starts on the DMD. This happens about 50% of the time, the other 50% the ball stays in the right scoop and doesn't eject till after the cross the streams mini-game is over.

Is this normal?

Thanks.

This is when I release/shoot a new ball. Prior to launching it I can use the flippers to select 2 skill shots on the DMD. The award video mode lights the right scoop. I usually select "light multipliers" and "award video mode". (sorry, said scene, meant mode in first post)

Just got it to do it again (twice). Selected the 2 skill shots. Hit the right scoop after launching the ball. Asks me to select ESP or Streams, selected streams, DMD then says "Symmetrical Book Stacking", (Scolari Brothers sometimes go up at same time), releases the ball from the scoop. Playfield goes dark, flippers lose power then Don't Cross the Streams starts on DMD.

OK, I think we are onto something. Turns out the Captive Ball Switch is always ON. In its normal spring-forward position it is ON, if I push on it lightly half way travel (like 1/16") it goes OFF then back ON again at full travel back. I'm guessing this isn't supposed to be happening.
Bumps of the field are enough to make the captive ball switch go into the off position (half way back). This would explain why I am getting Symmetrical book stacking and Gozer all the time without hitting the captive balls.

In the attached photo that is the status of the captive ball switch without playing or touching anything. Then if I press on the physical switch lightly it goes off and then on again when it touches the connection at the back of the switch.

Before I go tearing things apart ... can you advise how best to go about repairing it? (it is like the switch is making contact in the fully open position as well as closed position)

Thanks

It was the switch spacing.
Just lifting up the playfield an inch was causing the sensor to trigger back and forth. I removed the switch from underneath, it was working. Added a bit more gap and then also adjusted the bracket back a bit. Now it appears to be working as it should and those da*n Scoleri Brothers are not popping up every single ball now. I actually wonder if the glued on padding on the rear support bracket is not too thick (was pushing the back of the switch forward and making contact). Either way, working now!

Thanks all for your help!
