Hi currieddog
ipdb does not have the schematics to "Yukon" - I look-up in the Klondike-schematics.
Different pins have different forms of Tilt(s) --- a "mild Tilt" ends just the ball on the player who is playing. A "stronger Tilt" might end the whole Game for this specific Player. An severe Tilt (Slam-Tilt(s)) ends the game for all participating players - kind of toggle-off the pin.
We are used to have the mild form of Tilts - we shake the pin - but shake it too much - the pendulum tilt causes the Tilt-Relay to pull-in - ONLY the ball in play is lost.
An example of "my words: Stronger Tilt" is the Liberty Belle: http://www.ipdb.org/machine.cgi?id=1438 --- In a Four-Player-Game lets say the third player bangs a Tilt on the second ball - "Game Over" for this (third) player --- the other players play the rest of the balls. Yukon is a ONE-Player-pin with this "stronger Tilt mechanism".
The ipdb-manual "Yukon" at page-6 (ori 15) tells to the Ball-Count-Unit: The Stepper might step up to the Maximum "9 Balls to play". There is also: "During Reset-Cycle this Unit resets to ZERO".
Lets look at the ipdb-schematics "Klondike" - I show in the JPG on top the lights-section.
Williams and Bally pins usually trigger the "reaching state Game-Over, Game-Over-Relay trips": The Ball-Count-Unit steps a step too much - the brain of the pin says: Oooops - a step beyond what I allow to present the player - oooops - so I change to "Game-Over".
Lets look at the top of the JPG - in play shall be the last ball - see my "dark-blue arrow" points to "ball-1" - but the Tilt-Lite does not lite because the Game-Over-Relay is in state "latched - in play" - so the "encircled light-blue switches" are "as drawn in the snippet". We bang a tilt - the pulling Tilt-Relay closes "my encircled orange Switch" - the Game-Over-Relay is made to trip - "Game Over and Tilt".
Lets not bang a tilt - lets loose the last ball (called ball-1) --- on the bottom of the JPG: "encircled green" happens - the Outhole-Relay is made pulling so switch closes) - the Ball-Index-Relay is pulling (the ball in play has made some points) - switch is closed --- the pulling Outhole-Relay makes the motor to run - it closes its switch - the Ball-Count-Unit is made to step down - from position-1 to position-Zero --- the Game-Over-Relay-Trip-Coil is made to pull. And we see "Game-Over" lit in the Backglass.
Tru33 --- You know how the Game-Over-Relay acts when You make a Tilt --- this is "to TRIP the Game-Over-Relay". Toggle-off the pin and unplug the main power cord (Safety Reasons) - MANUALLY "TRIP" the Game-Over-Relay - then plug-in, toggle-on, start a game - what happens ?
To me the problem is "You either do not play ALL balls so the pin cannot do the stuff I wrote about" --- or You have a fault "along the wiring connecting my green rectangles / circles". Greetings Rolf
