Having a couple of issues with Houdini which I cannot solve so seeing if anyone else experienced these issues: The ball enters the stage but does not fully drop down cause the Newtonian ball does not travel far enough to let it drop. I talked to Barry at API and he is very helpful ns giving me things to try but so far no "Whalla." I did a stage calibration and it stays on -16 which Barry said was too high (Front and back stage optos not reading ball height correctly and it does not send the signal to the captive ball to release it's hold position. Cannot get machine to recalibrate to a different # other than 17 but it goes back to -16 when you reboot. Second issue is in the coil test A6B0-4 does not fire. Barry said it was the scoop coil. When the game is active and in search for a ball mode the ball shoots out of the scoop just fine which makes no sense (It should fire or not fire consistently). Have checked all switches and coils with the only bad test being coil mentioned above. Short of sending the computer and stage back to API any suggestions or experience you can share with this game.
