Having an issue with the right eject mechanism sometimes not reading that the ball is sitting on the switch. The switch sounds normal when you manually activate it but just to make sure I replaced it with a new switch. same results where the ball just sits on the switch until it goes into ball search mode. Switch is adjusted properly. When I test the switch in switch test mode and it performs flawlessly. Even the original switch was the same it performed flawlessly.

Sometimes the right eject works perfectly, other times it does not. When it does not work right the ball just sits on the switch and you can hear a repeating woosh type sound that seams to pulse. Then the game goes into ball search and kicks it out.

The game is running latest version 1.07

I have been working with Stern tech support for about 6 weeks now but no resolution.
Here is what has been done.
Switch replaced with new and adjusted properly. Actually replaced it a second time just to be sure.
Factory reset.
SD Memory card replaced.
CPU tested from another game.
Node boards 8 & 9 swapped and switches changed.
Switches 29-31, 1-3, 32, 39, 40 were checked per Stern tech

Yes, switch has been not only replaced but adjusted correctly. Wires have been rung out and inspected.

Forgot to update this post several months ago.
Solved- Did a factory restore and didn't make any setting changes except for putting it on Free Play. Worked perfect.
