Does it energize when ball one first point is scored?
It should not be energized after start up process, correct?
Not energized immediately after start up, so that the credit button will either add on more players or do nothing. Once ZB is activated, the credit button initiates a reset.
M and N switches cause ZB to activate when the two lowest scoring increments occur (1 and 10 for Groovy). The H switch causes ZB to activate if the first ball is tilted even before any score occurred.
The R switch is there so that if power drops off and is then restored, the credit button initiates a reset. Predecessor games Mini-Cycle and Polo did not have this important switch!

Studentprince thank you, was R relay.
Now all relays reset correctly and bounce switch works (wasn’t before).
I can’t get pb2 relay to fire. I manually engage relay P add player it doesn’t engage pb2 and engages control bank reset coil

P is the Add Player Unit relay, so it shouldn't trip the Second Player Unit (PB2) relay. Instead, the Start relay (S) should trip the Second Player Unit (PB2) relay.
To trip PB2 you need to operate the coin switch or the credit button after the game has reset. Either action will operate S. Which game is it?

I’ve got most of the game working properly but now after start up 2nd ball relay engages. Path looks simple but everything I’ve tried doesn’t work
Any thoughts

I had a Crescendo, the 2-player parallel to Groovy. Increased scoring of bumpers and lanes is stepped up based on which ball is in play. (Weird I know, but I confirmed that this was a deliberate design decision in that era.) For a 3-ball game, they would step ahead, so to speak, in the advancement of the score values.

dsquared_314 your schematic snippet shows that, when the game is set to 3 balls, 2B trips at the start of a game. When the game is set to 5 balls 2B trips at player unit step 4 which corresponds to player 1 ball 2.

Is there another path to engage game over relay, QB?

HowardR this pin is take two steps forward and 3 backwards. I press start and it goes thru the process like normal, reels reset, etc. then ball return coil keeps firing and O relay is continuously engaging.
It is not the outhole switch. So it’s going thru qb, o, m2b? Or could it be something else?

One or more of those 9 switches are almost certainly closed. Put pieces of paper between all of them and the motor should stop. Then remove them one at a time to find out which switch(es) were keeping it running.
