Hi guys, I have two issues currently on my Bank-A-Ball.

I took the playfield apart when I had new target-faces riveted on to the stand-up target switches (hat-tip to Boilerman for the great work last year on that). I finally got around to putting it back together this week, including soldering the switches back into the game. Somewhere along the way, I did something wrong because now the N relay (1 point relay) just rapid fires as soon as the game is plugged in (before I press start) and sets the score reel spinning and the bell ringing. the 0-9 unit continually fires along with it I believe.

I've attached a photo of the N relay portion of the schematic. Any trouble-shooting ideas to isolate this? I clearly did something while reinstalling all the playfield parts. I don't think any of the 1-point switches are closed, from what I can discern. Wondering if I dropped some solder on something, or...?

A second issue is that during all of this, the tab shown in the other picture broke off of that switch stack. I know how to replace the switch blade, but I don't know how to open up that stack given that it's riveted together and I have no rivet tool (nor am I sure how to take it apart). Ideas?

Thanks!

Thanks, Ken. Will do on issue #2. On #1, I'll go back and look but I can't see one that's gapped too close. I even held each of them open with the rubber next to each and it still did it. But I'll check again.

Will post a video

Thanks DaMoib, I will (carefully, unplugged) inspect those relays.

Here’s the video that I promised – sorry it has taken me several days to post it. I took the playfield out to try to diagnose the problem, and as you can see from the video the score motor is spinning without the playfield in, which leads me to believe the problem is in the bottom of the game not the playfield. But take a look and let me know what you think thanks guys!

Well, the hold relay is pulled in, the problem is it doesn’t let go. So I don’t know what’s causing the motor to just keep spinning.

I am not understanding that part of the schematic:

One more thing, the credit unit goes from 0 to 15 and rapidfire fashion when I plug the game in. So I can manually move it to zero credits, and as soon as I plug the game and it goes up to 15 really quick.

Thanks guys. I will revisit this this week and keep you posted. To recap, currently the play field is unplugged, and the motor starts moving as soon as I plug it in. I will check the switches suggested. Including the coin switches inside the door.

I got it working. I am not 100% which "fix" did it because I checked several things at once (the coin door switches, the SS, R and W relays, and also found a playfield switch stuck closed. Somewhere in there, I fixed it, and it now works 100% again and is happily back in its row between Lucky Hand and Drop-A-Card.

Thank you as always! I know I'll be reaching out in the days ahead as I embark upon my next restoration: Gottlieb Top Score.

I've been cheating and sending mine to Pennsylvania and Boilerman has done them for me (Target Alpha, Quick Draw and Bank-A-Ball) over the past few years. And agree, it makes a huge difference with nice red-white-and-blue (or whatever the color scheme is on particular game) target faces staring at you!
