This is that switch in the previous clip you sent I believe. Yellow/black and black. Normally closed.

Thanks for the advice! I’ll be testing this out in a few, which make break? The game over or the bonus relay?

Which side should be the make? Top of picture or bottom of picture?

Ok, cleaned the switch stack in the middle, (green/black wire and yellow wire) cleaned the make break on the top of the switch stack, gapped it to 1/16”. Issue remains.

Now when I turn it on, hit the start button on the front coin door panel. All the resets occur to start a new game, during this process the bonus reset relay does not pull in, in the picture I sent that shows it pulling in I had manually fired the bonus unit to lit the 1k pt circle, to correctly identify the relay involved. Otherwise that relay is not pulling until every ball on every player after ball 1 player 1. Hope that makes sense?

ArgosySK as I play around cleaning and trying to identify things. This relay I am not entirely sure what it is? If I am on a ball or player other then ball1 player 1 and I trigger this relay it triggers the score motor and the bonus will reset. While the correct 1k pt bonus will be lit before I trigger this it will not be lit after triggering this and the player up and ball up will not be reset from triggering this relay.

ArgosySK Mopar so some news here.... 1st the 1k pt issue does appear to be resolved. I spent a few hours cleaning contacts all over the cabinet. The 1k pt now lights on player 1 ball 1. As usual new issues crept up, 2 in fact. 1st issue, starting the game, now when I press the start button on the coin panel, sometimes it’ll start but mostly it does nothing. If I flick the coin switch then it will start (it’s been in free play as long as I’ve owned it and never needed credits on the wheel) but even then when credits are showing it won’t always start either. Then I play ball 1 player 1, it drains and then the outhole doesn’t kick it out. It starts the process I see the score motor cam trigger and move a tiny bit then it halts and that’s it. Please tell me someone can assist me here? So close to 100% functionality then get my hopes dashed like this.....

Also it’s not fully resetting the score reels now either, it seems as if it’s just pulsing the reset sequence long enough for that to happen like it used to?

Update I managed to resolve the score reels not resetting. It was a switch blade on the reset relay not making good enough contact. Slight adjustment issue resolved just have the other two issues remaining now.

I’ll just keep adding things I notice as I work to resolve so if anyone has any thoughts please chime in. I notice when the ball is in the outhole, but not being kicked out of I hit the right flipper button it shuts off the power as in kills the GI hopefully that helps someone point me to the right place.....

So I have checked these switches done some adjustments to see if it helps and am still not resolving it.
When the game starts absent the seperate starting issue, ball in outhole, it gets kicked out no issues. If you just drain the ball, not hitting any targets the outhole will kick out as it should. When you hit a target and that point lock relay activates (I know this is a game play Feature of Bally, you have to score for it to go to the next ball) that’s when it will not kick out. At first when I wrote this issue the ball would drop in the outhole, I would hear the coin door relay and the score motor begin but then immediately shut off. Now the score motor just continually turns.
To my untrained eye when the point relay lock mentioned above is pulled in something no longer triggers the outhole relay to fire, when that relay is not activated the outhole functions as it should....does that help any?

ArgosySK no apologies after all your helping me. Life and work are far higher priorities

I went to the credit u it and bent the contacts together further away from the EOS switch to not allow the game to start at zero credits, sanded and made sure they were touching harder together. As of my testing now that issue appears to be resolved. So just this outhole issue

Resolved! I appreciate all your efforts to help me through all of this! It ended up being that bonus zero make break switch. So at least for the moment the game is functioning 100% and I couldn’t thank you enough! Whew!
I had actually zeroed in in that and one other switch to look at when you wrote back so through this process I finally have a good understanding of reading schematics and that’s the greatest thing is finally understanding how that all reads! Thanks again, your a life saver!
