Fellow Playball owner checking in.
Don't see any posts from him here, but Rolf (I assume you're all seen his posts in EM help threads.) sent me a PM asking me to check in on this thread and wrote out some things for me to test on a working Playball:
From Rolf:
You once had this
https://pinside.com/pinball/forum/topic/gottlieb-playball-game-wont-end-xb-relay-not-engaging
problem. Do You still have the "Playball" ? We have an topic with a
problem "Ball is kicked-out automatically instead of 'caused by right
flipper-button activation' " - see
https://pinside.com/pinball/forum/topic/playball-doesn-t-wait-for-flipper-to-shoot-ball-except-on-1st-ball
. Please participate, tell us about relays pulling-in when a played ball
enters the Outhole in a fully running pin (Your pin). Take the playfield
glass off - start a game, play a bit the first ball - then take the ball
out, lift the playfield and secure it, put Your finger in the Outhole (You
simulate "ball is lost - enters and lays in the Outhole") AND watch these
relays - do they pull-in and stay pulling - does the motor runs
continuously, does the pin now step to the next ball - watch the relays:
The Q-Ball-Return-Control-Relay (I believe it immediately pulls-in and
stays pulling) - the O-Ball-Return-Relay, the P-Add-Ball-Count-Unit-Relay.
The questions above are all about "a ball lost enters the Outhole".
Then (with the finger still in the Outhole) press the right flipperbutton -
what does the motor do ? Do one or more of the mentioned relays change
state (non-pulling to pulling or pulling to non-pulling) ? The
Outhole-Kicker kicks on Your finger - take the finger out of the Outhole.
Does the pin now steps to next ball ? Please help, greetings Rolf
Wont have time to do this until tomorrow, but will be happy to do so and report back.
