Bally 809 underpaying

[wolftalk]

anyone else not happy with this?


the parts manuals show that "switch leaf" in there, and given it's width it does seem like it was intended to go between the eccentric bumper and the stop arm (or whatever you call the thing the red arrow is pointing to in the pic below).  Is it intended to help decelerate the impact or at least spread if over the rubber?


also, it seems really unlikely that the thickness of that leaf would make the entire setup not work, and the eccentric bumper adjustability is useless because it's set to an extreme end of it's range. 


if you look at davidlee's pictures, the stop arm at reset should be angled left/down and bottomed out in the hole.  Your arm is angle left/up.  Is it stuck in place instead of pivoting?  That would prevent the wipers from resetting to the correct position.

I don't have an old-style payout counter, hopefully someone who does can take a look and see if your reset position makes sense.

You are right, the leaf goes between.


I have two machines, one has the leaf between and the other does not.
Both of them pay correctly.


The one with the leaf between starts with the contacts on the receiver strips and steps 4 time then off on count 5.
Exactly like your machine did, but this machine pay correctly.

[DavidLee]

Note the leaf blade is on backwards allowing the switch arm to stop on the washer.
Which is incorrect, but works.
First chance I will make it right and test.

[DavidLee]

Okay, turn the blade over without making any adjustment to the washer/cam.
The machine works fine, it’s the 831-ze on the left.


So it looks like we’re back to square one.
The under pay problem.
Sorry for any confusion.

I’m on the second day of rigorous testing of the payouts on my Bally 809 , she is running flawlessly and paying flawlessly since I removed that “ limiter “ / piece of metal at the zero stop .
I’ll report back

The machine should have a 20 pay contact strip.
If you manually run the step up 20 time, I would be curious as to where it stops.


Also, you might want to check the carriage for free movement.
As not to bind up on the reset. Just a thought.

David ,
It’s working perfectly now. I’ve ran 1000 coins through it and it pays accurately, I’ll run 10,000 more through it and report back .

Sounds good, maybe there’s a little more adjustment on the cam washer as to put the metal piece back in.
Anyway, nice that it is running good.

david,


does your stop arm pivot freely on the stud on the right end?


lee,


something on your setup probably isn't right, but I guess you've compensated for it.   I like a reasonable explanation tho :-)


afaik on an electrically stepped payout counter, there's no adjustment that changes how the pawls grab the ratchet and how far the arms move. ... assuming the coil stops are good, nobody bent the tabs poking up from the frame, the ratchet teeth aren't worn, and the pivot point where the pawl connects to the arm hasn't elongated so the pawl behavior is erratic (part 42 on the below diagram.  It happens.  I changed one on a pinball machine a few days ago that caused erratic stepping).


if you're bored, what I'd do is:


1] take the payout counter off the hopper ... you can usually just remove the top screw and flip it down ... then manually step/reset the unit and look at what the pawls are doing.  Verify it's grabbing one tooth only on the first step. 


if when manually stepping it looks like it's almost going to grab an extra tooth, that's a problem.  The coil yanks the plunger in a lot harder than you, and it'll move the pawl a little more.


2] look at the traces and how the wiper contacts are stepping off them.  It's kinda hard to see behind the carriage, but if you step the unit far enough, the carriage may move enough so you can verify the shortest traces aren't deformed or burnt, and like david said, see if the wipers are stepping off at the right count. 


since they must be if you are getting correct payouts for all pays, now just need to figure out why it's working with the zero stop that far off the "normal" position.


in your video the unit was operating correctly when you were manually stepping it with the meter attached ... so what's different when the game is doing it?
