Hi Jeffcox007
I am not familiar with ONE-Player pins. To Your post-6: See the JPG - we toggle-on the pin - the Tilt-Light is lit because the H-Relay is not yet pulling (all good), the Game-Over-Light is lit because the R-Relay is not yet pulling (all good). From the lights on the Ball-Count-Unit we see: The Ball-Count-Unit has an ZERO-Position - this ZERO-Position shall be reached - then one step shall be done to Position-1 is "Ball-1" is in play. - Interesting I see a "Position-6 is "Game-Over-Position for an 5-Ball-Game".
See on the lower part of the JPG - starting a new game does actuate the Replay-Counter-Step-Down AND the "Reset Ball-Count-Unit". Toggle-off Your pin, unplug the main power cord (Safety Reasons) - manually step Your Ball-Count-Unit to somewhere in a middle position - also manually put some points on the Score-Drums. Then plug-in, toggle-on, start a game - when the Replay-Counter is stepped down by one - DOES the Ball-Count-Unit RESET ? I guess the Score-Drums do reset - then: Is the Ball kicked-over to the shooter alley ? - If not (but the motor was nice and friendly, did stop): "work" the ball (kick it over) under the apron over to the shooter alley - DOES the Ball-Count-Unit step-up ? See here https://www.ipdb.org/showpic.pl?id=2457&picno=29009&zoom=1 - on the way from the Outhole to the shooter alley the ball closes a switch (see switch in the upper right corner of the picture) - the TROUGH-Switch - closing this switch makes the Ball-Count-Unit to step up - in our test step-up from Position-Zero to Position-1 is position to play the first ball.
