809 N with chattering noise from hopper

[rdaniel]

Where is that coil located?

[wolftalk]

the one behind the coin mech is E-101-58A per the bally 400 manual, newer number is M-37-2700 per the 2400 manual.


grab manuals from http://bingo.cdyn.com/slots/bally_manuals/ ... there's exploded parts diagrams in them with part numbers.


you can prevent the armature tab from poking into the coin mech until the coil is replaced.  The game will keep coins if you drop them in before the game is ready to accept them, so that's the game to steer your friends to if you are letting them play with their money and keep any winnings :-)

Thanks to Wolf, this machine is working almost perfectly again.




No more arcing, pretty much  paying properly.  I replaced the ruined jackpot bell and now has great sounds!


Only issues now-  skips payment on a few combinations of wins.  Most do work.




Coins get hung often in the slide to the coin mech, and in the coin mech itself.  Typically a Fonzee style bang on the machine will get them to drop.

The skip payouts could be dirty contacts on the wiper boards.
Clean inside all the parts prior to the coin mechanism itself.
Use compressed air on the coin mechanism and check for any moving parts that might be dragging.

[wolftalk]

per david's post, clean the wiper board rivets with alcohol and green scrub pad or similar non-abrasive.  Anything that doesn't scratch the surface is fine.


if still have problems, the easiest thing is yank the reel mech and using the schematic and an ohmeter, verify almost zero ohms thru the reels by probing the appropriate pins on the beau plugs.  However, you don't have an 809-N anymore, so the trick will be to figure out what version of the 1090 the game has been converted to.  I'd guess from the reel strip symbols in your pics it's the base model 1090.


you can find the docs for that game at http://bingo.cdyn.com/slots/1090.   The 1090 used molex plugs and your game probably has the older jones plugs, but for payout you only care about the reel mech beau plugs and hopper beau plug.


to check the reels with an ohmeter, you'd put one probe on the plug pin for wire 90 and the other probe on the appropriate pin for the win on the wire that goes to the payout counter ... e.g. wire 23 for bars, wire 41 for plums, etc.   If you don't see almost zero ohms, push down on/wiggle the reel wipers fingers onto the contact plates to look for poor connections.

there's no guarantee the conversion is wired exactly like the 1090 would be.  Wire colors and the locations on the plugs could be different.  The way to tell for sure is:
- look at the wire color attached to the payout counter trace for the pay you want
- see where that wire goes on the hopper beau plug
- yank the hopper and reel mech.  Use an ohmeter/continuity tester/buzzer with one probe in the female hopper socket at pin position you just determined.  Probe the female reel mech socket to find the other end of that wire from the hopper socket.
- you can look at the wire color attached to the reel mech pin at the found position or just stick your probe on that pin and the other probe on wire 90 ... after you make sure you know where wire 90 or it's equivalent ...

Right Wolftalk,
The 90 wire gray should have continuity on every payout coming out of the left wiper board.
Another low tech test it to nudge the reels when they land on a pay and nothing happens.
If the machine starts to pay, one of three things.
Dirty contacts, wiper blade bent or the wiper blade arm needs adjustment.

[Phan000]

Cleaned wiper contacts.  Paying properly now.


Coins still sticking on occasion, but 99% machine is back in business.


Thanks for all the help and on to the next project!

[wolftalk]

coins sticking in the mech or the chute down to it?  Sticking is usually just accumulated crud in the coin path that needs a solvent like alcohol or acetone to remove.


got another mech to swap in?

[Phan000]

The coins stick in the chute & in the coin mech.  I swapped coin
Mech & Still has issues.


Probably need to get aggressive with some acetone.

[DavidLee]

Where exactly are the coins sticking?

If they don’t travel fast enough the coin won’t rock the cradle. If they go to fast the coins returns to the tray.

The magnetic sensor helps control the speed.


Magnetic sensor could be to close. There’s an adjustment screw for fine tuning the magnet.
Make note of the present adjusting screw position, then turn it in 1/8 to 1/4 turn.

Clean the interior of the coin chute. Apply a small amount of silicone lubricant, then wipe dry.

[wolftalk]

the manufacturer has manuals online for the coin mechs:
Welcome to Coin Mechanisms (coinmech.com)


there's adjustment, maintenance and theory of ops information.


suggest dealing with coins sticking in the chute first.  As david said, the speed the coin enters the top of the mech can change what happens in the mech.

[Phan000]

I cleaned the chute and the coin mech.  I also made a small adjustment on the magnet screw.


Ran 100 or so coins through, no issues. Seems much better, thanks.
