Well, I got the Bally manually # 1100.   I was hoping for a little more info on the odds follower and motor & cam assembly.  Not as much depth and description of function as I had hoped.  Still good to have.  Detailed parts description and exploded views.  Except motor / cam set up. 




Set machine back up for credit play.  It performed the same way.  Any win added credits to meter but when finished it subtracted six credits.  It basically was playing six credits.  I had looked in the cabinet upper section where the switch is and the contacts are open.  They close when button is pushed.  I went through schematic (Thanks again Jon) and decided to put a small piece of tape on C-3 mech switch since whether coin or credit is being play to coin up it has to pass through this switch.  Now, when I had the machine on credit play and set up a pay, the counter tallied the winning amount of coins to meter and did not automatically play six credits.  Ok.  So now I am thinking a switch is closed that should be open, back to schematic.   There is a "closed at zero" switch on register (credit counter) that would complete circuit.   If it is at zero the button switch to play credits won't work b/c theres no credits to play.  Thinking this is stuck closed.  While checking this switch (appears open), I looked at button switch contacts again but from a slightly different angle.  From this angle, I can see that someone had pinched the leaf switch arms together close to the insulator plates so the play credit button was always making contact even though where it should make contact was not touching.  Tight quarters so instead of fixing correctly (for now) in goes another piece of a business card.   


Bingo.   Credit play works like a charm.  Whether playing one coin to six coins, play credit button works.  Winnings get added to meter.   


So, right  now I need to put together a hit list of all the things that  need fixing, not just rigged up with bits of business cards.  Solenoid on hopper pay disk.  Fuses.  A bunch of cleaning.  Straightening out leaf switch arms.  And more when I sit down and look some more.


Since machine is working well on coin play and credit play and I have a schematic I am going to try and figure out the odds follower, count up disc and the motor / cam system.  I think my best chance of understanding it, is while it is working and I can see it working correctly.   


I hope I am not jinxing myself by saying all is well.  But what the hell. 


Thanks everyone for your help.  Old Reno, shout out to you on CO circuit.  Jon, big thanks for the  schematic, big help.

Jim if you need any contacts for that switch let me know. I just picked up a bag full of contacts. Some even have the plastic spacers at the ends. I just had to go digging in that bag tonight to repair a broken dash pot contact on this 809 that came in for service on Saturday. I couldn't figure out why the handle solenoid wouldn't fire to release the handle till i found a broken contact in the back right corner while vacuuming the machine out. It's nice having parts to fix machines without stealing them from a donor machine.

Thanks Gary.   I am going to pull the bank of switches this weekend.   I think I can get them straightened out so they open/close by using key.  I will send you a PM once I see how well leaf tool works.   Appreciate the offer and will let you how know it turns out.   

Thanks,
Jim

I had one of those straightening tool... I broke it!! I have a mini needle nose pliers with long thin tips that work nice. Got them from Sears. It was a 3 piece set of mini cutters and two different needle nose pliers.

Figuring out how pays work.   Playing in credit mode, the payboard does not reset for each credit/coin played.   Pay is done through cams and odds step up disc.  Hopper motor is bypassed. 

When a win is hit in credit mode for one credit played just cam 1 (12 pulse) is used and the odds step disc has no effect.  Each pulse from cam 1 adds a credit to register meter and steps payboard once.   

For a win for two coins, cam 1 and another cam (with 6 pulses) is selected by the odds step up disc.   Now when cam motor starts (instead of hopper motor) cam 1 still increases credit meter with each pulse but the other cam (6 pulses) the payboard step up once for each two coins paid.   

For a win for three coins, cam 1 and another cam (with 4 pulses) is selected by the odds step up disc.   Now when cam motor starts, cam 1 still increases credit meter with each pulse but the other cam (4 pulses) the payboard step up once for every 3 coins paid.

Cam 2 (10 pulses) is used instead of cam 1 for five coins played along with another cam, 2 pulses.   

Coin play and pay is interesting.  Still going through schematic, starting to make sense.

Hello Jim,
When you have time would you post a photo or two of the cam assembly your describing, sounds very interesting.

Hi Dave,
Here's a few pic of motor and cams. 
Actually for credit meter its a pretty good system. Similar to x units in a way.  Odds step unit picks x unit, here odds step up unit picks cams.

Here's some pic's of main components.

I was able to straighten out the leaf switches arms on the coin play bank.   When I would turn key to credit, the coin switches were still closed which messed up pay outs.   I can now turn key to either coin or credit and just the one selected works.

Think I found for brand new sets in storage today sweet

This will give you some information on one of the plates in that machine

Thanks Jon.   I'll print it out and compare.
