Hi TinyToo, HowardR +
I happen to like to do "work" in MS-Paint --- taking stuff and show it in an JPG. I show more detailled what HowardR shows in his post-2. A preowner did some work on the Replay stuff - adding "free play button" - taking out stuff.
Coining up an fully running Top Shot (see the JPG): The W-Relay is made pulling and the Score-Motor runs to make a third of a revolution (Gottlieb Score-Motors are built 120 degrees symmetrical). Within this turn of 120 degrees the motor closes FIVE times motor-1A-Switch (marked green in the JPG) --- when the 2nd chute adj. is plugged-in at "please five replays": A Jumper jumpers a distance - jumpers motor-4B, -4C, -2B switches. The FIVE pulses from motor-1A reach the Replay-step-up-Coil.
Look in the Motor Sequence Chart in the JPG --- Switchstack on motor-4B ("my brown") actuates before - while - after "motor-1A the third time" actuates --- the opening of motor-4B suppresses the third shot of motor-1A. Same with motor-4C (my blue) and 2C (my yellow).
Maybe (but probably not); The preowner has wired "3 replays for a coin" - connecting wire-of-color-black-mingled-with-white (?) to solder-lug on motor-4C and/or solder-lug on motor-4B - to the connecting wire BL+BLK. Maybe - probably not --- I am now just guessing: motor-4B or motor-4C or motor-2C is faulty - NOT TRUELY opening. I have never done the "unplugging the wire that feeds electricity to the real motor --- then manually slow turning the motor" - listen WHEN does the Replay-Unit step up --- figuring out WHAT switch (three do) on motor-1A makes the Replay-Unit step-up --- You may try just starring at the motor (normal speed) and listen to the Replay-Counter --- OR YOU may simply check the switches and the wiring on motor-4B, -4C, -2C (?).
"bonus not consistently": I do not know the pin (well, have played it some 40 years ago) --- please write in detail about the problem. Greetings Rolf
