Fireball Classic
Bally, 1985Having no real knowledge of S/S electronics I'm hoping this is an easy fix. The problem is the two top bumpers fire together and is not caused by vibration and possibly the third bumper as well, this is while a ball is bouncing around. Any help on this would be great. If this is a problem on any of the boards I'm in a real mess. This is the last problem to solve on an otherwise perfect game. Thanks
Thanks. You don't happen to know what I need to order from ebay? We also have an electrical store in the UK called Maplin, I might strike lucky there.
A bit later
Just checked the store would it be known as a Decoupling Ceramic Disc 0.1 or 0.01uF Capacitor?
You could clip one leg of them off to see if the problem goes away. The switches will still work, just won't be as responsive.
Quoted from pinkid:You could clip one leg of them off to see if the problem goes away. The switches will still work, just won't be as responsive.
Thanks, I will do that later today. I can only say this is getting much worse and don't think it happened when first bought a few weeks ago. It would be great to get it normal again
Quoted from Ballyoldboy:Thanks, I will do that later today.
Couldn't wait....
pinkid you are a genius. You have fixed my Fireball Classic. The bumpers seem to trigger instantly ...... no delay that I can detect and the ball stays amongst the bumpers much longer, like it was designed to do. (No double or triple thumping at all) I am so grateful to you. Big man-hug
PS can't see the point of those damn capacitors

Pop Bumpers missing the capacitors will miss scoring when hit at high speed. Suffice to say one or more of those caps you cut out is faulty. Use 0.05uf capacitors as replacements.
Simplified description, the old circuitry scans the switches to see if one of them is closed. With a real quick hit to a switch it might get missed. The capacitor adds what can be considered a delay.
They are probably 20 for $1 so replace them when you get a chance.
Thanks for that explanation. I know my way round the old Bally bingo's, but I was always worried about buying a s/s machine with my zero knowledge, but I'm really hooked now on flippers and the e/m flippers don't seem to do it for me, if you know what I mean. This brilliant site rocks and I feel more confidant on my next game with you guys around.
Consider this problem solved

But remember, the problem is not solved until you replace those capacitors.
Clipping them does not give you the full impact of the game.
Buy 100 of these, because if you have a Classic Bally, you will need them for many of the switches.
100 of them for .90 cents:
7-10 day shipping to the UK from Taiwan.

Very kind of you to remind me that that I need to do more than just forget those capacitors.
Having 2 or 3 coils triggering together must have been a strain on something and at least reduced the strength of the "thumps". I bet the ball was smashing into the lip of the plungers. I might replace with some nice chrome ones.
I believe there is a thread on these caps. Maybe not. There is some info on PinWiki. Anywhere there is a cap on a switch on an old Bally it would be best to replace 'em all. They are cheap enough. Switches will work w/o them, but not like they are supposed to. All hits may not register w/o them. Glad I helped out. Feels good when a game gets going again. Sorry I don't know exactly what caps you need.
Quoted from vid1900:If you replace the ring rods, remember you have to polish them or they scratch up your balls.
Now that bit of advice sounds like a professional secrete.
I shall visit those pages in the morning. Many thanks
