Quoted from rai:help, I'm having two issues that have just started occurring on my RR Woz.
1) I adjusted the coil strength down because it was having trouble ejecting into the shooter lane, and it started working fine that is until today when this is happening:
the ball will be ejected from the shooter lane and I will be playing the game and all of the sudden another ball will be put in the shooter lane and will be auto-launched into play, and when I drain one ball it will end the ball. So I am thinking something to do with the ball trough.
2) I was having a small issue with the ball lock mech where it would drop out two balls instead of one such as when you shoot a ball up and there was already one locked. This has evolved into a situation where the ball lock (U shaped metal fork) will just all of the sudden start popping up and down for no reason and sometimes will pop up when I press the left flipper button to the full position, not the staged position. And also one time got the ball in this lock when it was not supposed to be and it was just stuck without any notion that the ball was locked so it needed a full ball search to be freed.
Helping Phil today I observed this issue and wanted to see how to troubleshoot. First time working on a JJP...
That ball lock mech def has a mind of its own. Would go up or down for 30 seconds non stop sometimes. Other times it would be in the down position and whenever he hit left flipper it would go up and down...What was weird is that it did not happen on right flipper. On a B/W pin I would suspect a flaky opto or switch causing the issue. Ive never worked on a Woz but was thinking about the 3 bank opto where balls rest when locked? thinking a flaky opto or cold solder? Any help would be appreciated. Great pin by the way!
