Working on a Williams Lucky Ace. I was able to get the game shopped, replaced the power cord and get most of the issues sorted out. One score reel and the game over relay coils were fried, so I replaced those.

But I have one issue remaining.

When you hit the start button, score reels reset to 0, stepper moves and the ball is about to kick out of the trough. But...the bonus will not reset properly and keeps advancing the score reel by 1,000. Ball then doesn’t kick out.

I can kick the ball out manually, which ends the bonus mech running. Plays normally.

Sometimes when it drains, everything resets properly and the game plays. Other times, the bonus mech just keeps running again after each ball.

I’ve checked every switch, nothing arcing. No loose wires, rechecked stepper and bonus mech. Don’t see any other issues. Driving me nuts now.

Video below. Any help would be appreciated.

Actually a second issue. None of the chimes are working either.

Opening it back up now. Thanks much! I’ll report back.

Which switch and where is it at in that circuit? My bonus relay is attached to a bracket on the backside of the PF.

And the outhole relay is on the transformer board in the bottom of the cab. They look more proximal to each other in the schematic you posted.

All of that is done already on the trough and kicker arm. Disassembled it all, thoroughly cleaned with new sleeve. Works smoothly and properly. I’ll check out the switch on the score motor cam.

Well I hit that whole stack with Flexstone and must’ve adjusted something wrong...no reset, score reel reset doesn't initialize and ball won’t kick out at all. The score motor cam just keeps running nonstop.

Getting back to it in 15 min. Thanks fellas.

I was referring to the 4th switch stack on the motor cam.

This is driving me crazy. No matter how I adjust the second switch up, it is not in the open position when the bottom switch tip is in the divot. It just stays closed due to the plastic spacer.

Either it is continuously closed even when in and out of the divot, or continuously open.

I thought you were right the first time. Am I not correct that the yellow circle indicates closed, and the green circle open?

And that is with the switch cam in the normal position, meaning the switch not in the divot, correct?

So this means that the third cam would be in the divot, being it’s normal position for opened or closed designation on the schematic?

Awesome. Thanks.

The game started having other issues, so I jumped off it for a little bit to take care of other things. I’ll be jumping back on it tomorrow.

500+ the game I have? Good to see you are still you. LOL. Hope Gerry is well too.

This isn't my game, I’m repairing it for a friend’s dad. Already did a ton of work to it, shopped it, etc. Was weeding through the last few issues after adjusting a ton, replacing burnt coils...and then it started having functional issues. All switch and relay related now.

Good to hear from you though man. Take care and stay safe. I’ll reach out to you once I dive back into this thing tomorrow night.

Awesome. Thank you. I’ll check back in when I crack it open tomorrow.

OK. Done playing games. Ripped it open. Hate adjusting the switches on the scoring motor with the transformer board still in the game.

I wish Williams did the hinged transformer board lift like old Bally games.

And I think I solved the chime issue. Two of the coil sleeves were all gummed up and the pin wasn’t even striking the chimes. Switched out the sleeves.

Start button won’t do anything now. Seems dead. Game will only start by manually rotating the wheel on the coin chute to engage the leaf switch. Then it plays one ball, but won’t advance or do anything else once the ball drains.

Great. I’ll read through it and give it a whack. Thanks Howard.
