Working through my Eight Ball Deluxe. Sometimes on quick rollovers the A,B,C,D or outlane specials don’t always register. I adjusted and cleaned switches with a business card. Is my next move to add caps or to replace the switches?

Usually caps on rollovers are not needed. Replacing should help. It maybe a good idea to repon the female switch connectors coming off the cpu board as well.

clean and gap the switch properly is probably key. if you still have trouble add the cap.

Thanks for the suggestions. I'll work on them some more.

If there isn't a capacitor on the switch you need to put one on. It's shown in the schematics (see page 23 of the pdf):

It's a .05 mfd. It will defiantly make a difference in play.

Rollovers must have caps. The switches are usually hit by a fast moving ball. Early 80’s Bally all had caps on every rollover.

I tried it but it causes false triggering of the rollovers. I cut them off and ordered new rollover leaf switches.

You tried it with the original caps or new ones? They are a must.

They were new. I even opened the leaf contacts but I still had some false triggers. I figure new switches are worth a try at this point. If that doesn’t work I’ll try a new batch of caps from a different source.

Old thread. New switches and new caps. Rollovers working much better but still not 100%. Quick question. I don’t have the schematic. Does anyone know which board connectors the rollovers are connected to? It seems like sometimes a rollover may not register if the game is “talking”. Especially the right outlane rollover.

Check your switch gaps.

Thanks. It was pretty close but I just adjusted it to about 1/32”. I’ll see if that helps. I found the manual on IPDB. Looks like J2 on the MPU board controls the switches. It’s an Alltek board but the connectors might need to be repinned.

Adjust them with a ball. Make sure the ball hits the switch and closes it towards the middle of the stroke(watch the wire) If it closes the switch too early you’ll get phantom closures.

There’s no perfect gap in inches. The switch wires get deformed. Use the ball and your eyes.

Will do, thanks.

Occasionally a ball will fly out the outlane(s) on my EBD and I won’t get the sound effect because another voice or sound effect is already in progress. It is scoring but that always makes me wonder for a split second, because I’m not eyeballing the displays - “did it score?” A voice effect can be interrupted by another but they have priority over sound effects so they aren’t constantly being chopped short.

Interesting. Thanks for that info. Same thing on mine. I have definitely noticed on occasion that it does score correctly without any sound effect because a voice command is in progress. I’m convinced however that sometimes that right outlane just isn’t working 100%. I’ll mess with it some more this weekend.

I've definitely found on my early Ballys that it can only handle so many sound effects at once, and the points will register without the sound.
