Hi Brewchap
I do not know all posts --- in post-25 4Max shows the wiring of Outhole-Relay and Ball-Kicker (named Outhole Kicker Solenoid).
In Your snippet in post-39 (WHAT pin is it from ?) I see the activation of the Kicker --- if the Outhole-Relay is pulling and the Score-Motor runs and so the turning motor closes its switch "Score-Motor-4B". Big question: DOES the Down-Post-Solenoid fire - see http://www.ipdb.org/showpic.pl?id=3070&picno=49500 - above the right slingshot.

The brown line in my JPG: After a ball is lost then the Bonus is counted down - then along brown lines the Outhole-Relay is made pulling --- it establishes Self-hold-Current along "green lines". Greetings Rolf

Hi 4Max (and Brewchap)
I did not really want to post in this topic as You are helping. But Brewchap was trobleshooting and asking (and asking) --- so I said to me: Brewchap has time right now and he wants to work on the pin --- I help out with an explanation. 4Max please: pardon my "jumping-in" and proceed "helping in troubleshooting". Greetings Rolf

Hi Brewchap
unfortunately "No" - I never had this pin - I look at it in ipdb --- a fun pin with (rather) rare "chance collecting bonus with ball in play landing in the Eject-Hole".

You must do some "detective work" --- here http://mirror2.ipdb.org/files/3070/Sonic_1978_Cherry_Bell_Instruction_Manual_English_and_Spanish_no_schematics.pdf on page-13 are the relays listed --- Mech. Panel is in the Cabinet, Insert is in the Backbox and You must look at the relays "playfield": We see (for example) that the UP-Post-Coil (playfield) has an Coil "M-29-1000".
Starting in the manual on page-29 ALL the playfield-relays are shown --- You must use the manual and check with Your pin --- or hope for some pinsider to write the needed information. Greetings Rolf

Hi Brewchap
I do not really like the feature in late-70ies pins - the feature "EVERY new ball given starts with ONE bonus given" --- this "giving for free one bonus" makes the pin (more) complicated.
In a fully running pin: Start up ... Outhole-Relay pulls-in - makes the Ball kicked over to the Shooter-Alley AND makes the Bonus-Ladder step-up one step.

See the JPG, "encircled rosa / pink": If the Switch on the Outhole does not open when the ball is kicked --- the brain of the pin believes: A ball has been played, lost - there are bonus on the bonus-ladder - must count down --- then the Outhole-Relay pulls-in (again) - kicks and adds the free bonus ... this sequence again and again.
I would investigate on the switches "encircled rosa / pink", greetings Rolf
