This issue is a cluster fuck .
Quoted from nicoga3000:
Pat: Do optic switches 33 and 34 register during switch test? Do either of these switches register during switch test if you pound on the playfield?
Me: Switches register during switch test and do not register when I pound the playfield.
Pat: Try reseating the (2) and (5) pin connectors going to the opto amplifier boards under the playfield. Also, inspect the wires going into the connectors for poor crimps.
Me: I checked everything and played a few games. Ball is still sticking. I noticed that it stuck with the right flipper one game, and the left flipper on another.
Pat: Please swap the amplifier boards under the playfield and see if the problem persists
I have done all the above and more. tested every opto wire by taping pounding tugging on wires in switch test trying to get the opto to trip. Nothing . Opto only trip when beam is broken as intended . Swap of amplifier board did nothing to fix flakey issue. I tapped on all boards and pulled on all wires in switch test . Optos will not trigger if beam is not broken as intended. Wire twisted ferrite core beads in place . If all boards work and all switches work . Why does my STLE not work during Vengeance Muti-Ball 45% of the time ? STERN is sending me all new optos (4) and a new amplifier board . But the components that are in my pinball already all work 100% according to hours of trouble shooting testing . Any thoughts I am at my wits end.
Played and documented 35 games regarding Vengeance magnet issues .
3.flakey = pinball on magnet . Shot second pinball into area breaking opto# 33 but pinball did not stick nor did it release ball on opto#34/magnet. Second hard shot released pinball on magnet and launched 3rd pinball into play .
6.stuck = pinball one and two stuck together timed out then released.
23.normal . got to second Vengeance where magnet grabs pinball. Second pinball stuck timed out
Note : Due to this annoying magnet issue. I increased the time to knock / trip opto#33 . If pinball's get stuck together and you nailed the shot quickly . Do not touch flippers. Machine will go into ball search while the Vengeance timer has not reached zero. Magnet will release stuck pinball's and trip opto#33 on the way out and 3rd ball will be plunged into play. Open to all suggestions. Thanks Rob Knapp
