Hi drsfmd
I like to have the JPGs I post in a form "746 times less" --- I show a snippet of the ipdb-schematics --- squeezed.
I can create an connection when I make the Score-Motor-Switch "1-B" (encircled red in the JPG) FAULTY ALWAYS closed. The "marked green" switches are entitled to close / to be closed at the time Your fault happens --- and it happens in the pin to be SCM-2A and SCM-2B: They sit on the SAME Wheel --- actuated AT THE SAME TIME.
Do not hurry with "adjusting SCM-1B" --- check my theory: I assume Your pin starts every new ball given with ONE bonus given --- if so: With my "faulty always closed SCM-1B" - when Your pin changes to next ball: You should see Your Bonus-Unit-Step-UP-Coil pulling, pulling, pulling all the time the Outhole-Relay is pulling. So look in Your pin --- play a ball, loose the ball ... Outhole-Relay starts pulling, stays pulling for a while --- question: What does the mentioned Bonus-Unit-Step-UP-Coil do at this time ? Pull and let go as the SCM-1B is good ? --- or: Pulling as long as the Outhole-Relay is pulling means SCM-1B is faulty always closed (?). Greetings Rolf
