Coin-In Jam S2000 Triple Double Stars 5 wheel

[ThirdGenAmusement]

I thought, with a lot of help from the great people in this group, that I was ready to call this machine done.  Then this happened!

I now have the 'Coin-In Jam' error.  I had been playing the machine and needed to get back to actual work on the computer so I left the slot on.  It had been on for hours prior to this no problems.  I smelled that funny smell when something electrical gets hot so I popped open the door and confirmed it was the slot.  I shut off power to it and looked it over.  I didn't see anything that appear like it was hot so I turned it back on and got 'meter disconnected' error.  I had previously tied the 9 and 10 wire of the jack together to bypass the meters since they were running constantly and in bad shape.  I will include a pic below of the wiring I tied together just to be sure this isnt part of the cause.(After posting this and doing more searching I did come across the post in the 'Check Here First' sticky that Foster made and my wiring checks out per his instructions.)   And by tied I mean spliced, soldered and heat shrunk. I powered down the machine, reinstalled the jack back on the meters, turned it on and all was ok except the meters ran.  I powered the machine back off, unplugged the jack from the meters, turned the slot back on and all worked fine.  I played off most of the credits that were on the machine with no issues.  I got down to about the last 1.00 worth of credits and wanted to have the machine pay in nickels, so I cashed out which it started too but stopped with the error 'Coin-In Jam'.  I googled this and found a thread here which I tried many of the suggestions. This is what I have done:

Both the I/O boards on the door have amber led's.  One, the one between the belly glass and the door has 2 amber led's, the on on the opposite side has 1 amber led.

I read that the typical are these.  I switched them in their locations in the machine and they lit exactly the same led's as before even though I switched the boards.

I unplugged one, turned the machine on then did the other I/O board with no new errors. 

The coin comparitor led is lit.  I did unplug that with no change as well as unplugged the device directly below(also pictured with arrow) it with no change in errors.

I took the coin hopper out with no success.

The door optics seem to work as I had tried to also clear the error that way and the machine responds to lifting and lowering the latch for the door when its closed.

I hope I didn't smoke the board.  Any thoughts or things to try?

I should note that my initial issue with the machine was it simply wouldn't boot.  Only the service light in the cabinet was lit but no other power to the machine.  I had discovered tokens behind the board that is mounted to the cabinet the main cpu board gets slide into so I removed the cpu board, loosened the screws that attach the board to the cabinet and was able to get the coins out.  I verified no more coins by using a video endo scope.  At this point, the machine ran and powered up with no apparent problem surprisingly. --End of full disclosure   It would be easy to say this took the board out however as I mentioned once the coins were removed the game functioned 100%.

I have another s2000 that is known to work with no errors but currently has the 502 board. Not sure if I can put the problem machine board(1270 enhanced) into the machine without issues though it is running/set up for the 502?.  But if I could, that would confirm board if the error carried over. Just not sure if I can just swop them out.


Also, the I/O boards in the machine with the issue are 802's.  The I/O board in the working machine is an 801.

The cut and spliced wire is just to stop the meters from clicking. The unknown device is the coin optics if dust gets trapped in there it will cause your coin in jam.

Thank you Retro Tech Repair for the suggestion.  I pulled the optics apart, cleaned with Alcohol and reassembled with no change.  They were dirty though!  I had previously unplugged that and the comparitor with no change in error or symptoms.

Thank you for your time.

Here are pics of the main board without the sister attached.  The other pic is a close up of the Varta battery and immediate area showing no signs of damage.  The watch battery is spot on 3v.  The Varta however is 3.9 so its a little high.

No, you can't inter change those boards. Very odd that cashing out caused a coin in error.

Thank you. Glad I waited to try.     If I were to find another s2000 with an enhanced board set up, Could I give it a whirl in it? 




Yes it is strange.  I initially thought it was a coin in the comparitor or in the hopper but not the case.  Unplugging the i/o cards, comparitor, etc doesnt seem to change the error or add to them.

Like Elvis stated, very strange to get a coin in jam when cashing out. A coin out jam would be more likely if the hopper malfunctioned. Coin in/out jams could be I/O related. Examine both door I/O cards & smell them to see if the burn was coming from one of them. I have plenty of 802s if needed.

Next, why does anyone even want a coin in/out machine that takes 4.5 rolls of nickels to play one spin at max bet?  That makes no sense. Coinless is the way to go for anything that takes more than 5 coins for one max bet.

I used to get customers all the time that would request high credit machines setup with coin. Usually it would be $.25 coin denom and a $.01 player denom. Then I would get calls “my machine keeps making me hand pay I thought you put coin mechs in it”. Yes but i also told you that would cause errors unless the credit amount was divisible by the coin amount. I also got in a bunch of machines that were set to $.03 at the casino and it was a 240 max bet. Sure enough everyone that saw it “can you make that coin”.

Hi RB,


Both I/O cards have the plastic cover on the back but one is slightly warped.  There is no discoloration to the plastic but the warping may indicate it getting hot.  I did smell something getting hot prior to this issue.  So something had to get torched.  Both I/O cards have amber lights on.  The one between the belly glass and inside door has two.  The one between the door and the inside of the machine has one.  I have swapped them around and the number of amber lights stay the same for the location meaning the card between the belly glass and the inner door has 2 led's no matter which card is in it as does the card located between the inner door and the inside of the machine has 1 amber led lit no matter which card is in it.


The I/O card thats between the door and inside the machine looks like it controls the line and play line buttons while the I/O card between the inside door and belly glass runs the Spin reels, max bet, cash out, and attendant buttons as well as it looks like it would have something to do with the red X's readouts on the left side of the reels and the red Winner paid, Credits, and Total Bet read outs.  These red readouts do not work regardless after getting the error.  However the blue readout that states the pricing and displays info works regardless if one or both I/O cards are removed.  I want to lean towards an I/O card being bad but both have ambers on and same thing happens when I switch them.  Grrrr.


I can disconnect the cards completely from the machine and power the machine on and the only change is no lights on any of the buttons but same errors.

The more info im seeing the more it sounds like one of your senet devices is fried. These can sometimes be difficult to diagnose because they are all chained off one another so if you end up with a device that’s enable is stuck the game cant tell what parts is actually talking and can show the wrong errors or random errors. The only way to find the fault at this point is to test everything.
Senet devices And what they control are.
Cabinet io board(the one mounted to the mpu tray).
   Candle
   Meters
   Hopper
   Handle
Door io boards.
   Between belly door and door plate (can be 801,802, or black card).
      All basic door buttons (change denom button not touch pannel, max bet, spin, bet one, cash out, service)
      Coin comparator and optics.
      Bet line lights (not bet line display).
   Door plate into the machine (has to be 802 or black card).
      I believe this one only controls the 2 rows of line bet buttons.
Credit display
   5,5,2 only controls itself.
   6,6,2 controls itself and the multi denom touch panel.
Bet per line display.
   Only controls itself.
Backlight reel driver.
   Only controls reel backlights.
I usually start with the cabinet io card i have just seen it fail most often. You could also have a bad mpu but i have never seen and enhanced board fail in this way it’s usually the 50x boards that have senet faults (buffer ics like to go pop).

Thank you Retro tech repair for the in depth explanation of the Senet.  This confirms and definitely more what I was looking for!  I have a couple of I/O cards coming from a great member of this group the help be able to switch them out and see if that is in fact the problem.  Per your description it really leans to being one of the door I/O cards.  I do have candle lights but due to the error is the only function present of the cabinet I/O card.  I hope to have the cards here Monday so will definitely report back.

OK just to confirm,once the I/O cards were replaced the machine is up and running.  I did get a 7 segment error, which is in another thread, but was also solved with the key chip.  Thanks to all who tried to help and to RB for the parts and chips.  Its alive!
