I got an S+ Double Diamond w/ IGT SP872 game chip. Upon plugging in I got an error 12. The previous owner had purchased a replacement battery that didn't have leads and couldn't get it to sit correct so they gave it up to me (for free!!). They were trying to solder directly to the battery.
I purchased the correct battery with leads and soldered to the board. Confirmed 3.6VDC to the board w/multimeter.
While I was waiting for the battery I did my homework and read through forums and the field service manual. After powering on after the battery swap, I got error 61 as expected. I closed door and hit the reset key. The "Coins Played" show 0-1-0, the candle has a slow top flash and a fast bottom flash. The manual tells me that's an "All pays door open". This is where I'm starting to fee doubtful about my troubleshooting...
I believe this means that the optics are sensing the door is open. Please correct me if I'm wrong. I used my cellphone to see if the optics are functioning. I didn't see a pulse, but the optic mounted to the door looked like it had a faint constant transmission, it was really tough to tell. I'm thinking the next step is to replace the optics. I'd really like to get the machine functioning, even with a temporary fix on the optics to make sure the machine as a whole functions. I'm ok with ordering new optics if that's what my next step is, but hoping for some pointers or tips just to make sure I'm on the right path here. Looking forward to being a part of this community too!

When you get the 61 you have to hold the white reset button till you hear a ding or for 5seconds
and you get 61 1 on the display.
You then shut the door and turn the reset key.
-
Thanks, after reading into this some more you are absolutely correct. I powered on and let it get to 61 again. I held the white reset button 2-3 seconds and heard the 'ding' and got the 61-1. Close door and hit reset key. Looked good for a second then gave me a 61 again.
I tried the white reset button again but now no response from it. I powered the machine down completely and back up, back to 61 error and still no response from white reset button.
I'm guessing I'm now in the "61 loop" I've been reading about. I read all the warnings about using a clear chip; before I resort to that option, is there anything else I should try?
-
No your in the 61 loop and the only recourse is to do a clear and setup.
-
That's what I figured.
I haven't seen much documentation on what to expect when I do one. Is there a guide anywhere or step-by-step? I'm an IT guy comfortable around electronics, just first time I've "dabbled" in slot machines. I see the chips available on ebay, does anybody recommend other sources for obtaining the chips? Once it's cleared, what can i expect for the setup process?
-
Here is the PSR for your SP872 and a old set of clear and set instructions.
:NLG_WELCOME:
-
If you change your sp chip to a sp1271 it will force an init of the eeprom and it will get you out of the 61 loop as well.
-
Thanks for all the good info. Going to get hold of a clear/set chip set.
-
So I've made some progress, I think...
I ordered a clear and set chip on ebay. I replaced the game chip (SP872) with the clear chip and powered on. Pressed the white button twice and watched the credits played counter count up twice ending at 999. I powered down, replaced the clear chip with the set chip. I followed instructions to turn BV on and set the denomination to .25 (this is what the machines marking has above the coin slot). I powered down and replaced the set chip with my game chip (SP872) and powered back on. With door still open I received the 61 error. I pressed the white button, heard the ding and got 61_1. I close the door securely and turn the reset key and I get no response. I have tried opening door and pressing white button, closing and trying again, the machine seems to stop responding once it gets to the 61_1 error. Suggestions?
-
After spending all day working on this, I was able to get past the 61 errors. Lots of trial and error eventually got the machine working properly. The bill validator accepts dollars and denomination is set correctly (.25). However, the coin comparator is not functioning. The small red led does not light up and coins just pass thru to the collection tray. I checked voltage w/multimeter on each of the pins to the coin comparator and only read fractions of a volt... What should be the proper voltage thru the pins (black I assume ground, yellow, purple and red is loopedback to last pin).
-
Silly question, but I'll ask... is there a sample coin in the CC? ;D
-
Yes, there is a quarter in the comparator.
-
That's good !
I'm not sure on those voltages, but the other thing is to check all connectors at both ends...making sure the little pins aren't squished and not making contact, as well as checking the wire connections.
-
I have checked all connections, everything looks good.
-
Read as much of this thread as I could. Now I am assuming your game works and will take bills but the coin in does not work?.
-

That is correct. When I open the door, the little light on the comparator is not lit up. Coins go straight through to the collector tray.
-
I have also checked all fuses, which checked OK. Confirmed continuity w/multimeter.
-
S+ CC lite will always be off when the main door is open. Same ans. you won't get a voltage reading with the main door open. Other than bypassing the door optics, you can open the belly glass door and get a reading with the main door closed. ( The CC needs to be hanging down to where you can get to it )
-
Game plays fine with credits on it from bills being inserted. Just won't take coins. I would double check your settings AND I would clean the optics in the coin drop. To not have any pwr to comaparitor may be another issue but keep in mind if you have it set up prop. the mpu/cpu does not recknonize it. Also the coin you have in there Must be properly seated and indexed in the comparitor. Simple things to check but I have also seen strange problems as well. Not a s+ expert as I am quite rusty -Just trying to help.
-
Barry If the coins are going to the tray, that leaves the coin optics out as the problem. Now I'm not saying the coin optics are good, we won't know until a coin goes to the hopper.
PStuart I do not recommend this as a fix but as a test it's OK. Pull the comparator out and on the backside of it you will see what we call a rake. Using a folded up piece of paper and block that rake open. Install the comparator, drop a coin in and see what happens. Now here's the CAUTION when that rake is blocked open each and every size coin known to man will go to the hopper. Makes a big mess if someone hits CASH OUT,
-
I Must agree with your techinque as it is old school. I am working on trying to remember as I do not have a canidate in front of me. Have to think back to s+ days . The game works fine, No errors, Just won't take coins. This member I think will triple check all and Let us know. Here is a question. After it was turned off from working (except taking coin input) did it return to a working status less coin input?.
-
As Buzz mentioned, you'll never see that light on under normal circumstances.
Adjust the comparator sensitivity so that it's less likely to reject coins. Using a tiny screwdriver, turn the dial all the way back and forth a few times to make sure it's making a good contact, ending up dialing it away from the plus, then see if your acceptance improves.
Using a tiny screwdriver, adjust that counter-clockwise (away from the +) to make the comparator less sensitive -- that'll let the comparator reject fewer coins.

I played with the screw at both extremes and several steps in between with no luck. I did notice when comparing Knagl's photo with mine, it appears I'm missing a screw on what I believe is part of the "rake assembly". I've tried comparing to other's photos but I'm unclear if it is supposed to be mounted to something or what that screws function is. See the image:

Looks like your CC is missing the counter-weight. The function of the weight is to slow the coin down to a speed that the optics can analyze the coin and do its job. Not needed necessarily on smaller coins (dollars, yes it's needed).
On the adjustment, best way to know you hit all do the adjustments is to start all the way to one direction, then adjust 1/4 turn at a time and see where you get.
What happened when you propped open the rake on the back as Buzz suggested?
-
What your missing is a counter weight, will work fine without one. The rake is on the back side, and it is is like a door, if the comparator decides you dropped in a good coin that rake will open and the coin drops out the good side of the comparator, through the coin optics and into the hopper. If a bad coin, the coin will drop out the bad side back to the tray.
On a S machine you don't have to but if you disconnected the power with the rake blocked open all coins will go to the hopper, it's acting no more than a coin chute.
-
Buzz...don't say what I say!
-
I didn't say " Oh S**t " at least not in this thread. :Scratch-Head: :Scratch-Head: :Scratch-Head:
If I type it I'm gonna post it, I don't care how long I take.
-
When I block the rake open (outwards) from the comparator, the coins go through and into the hopper. The machine does not recognize that a coin was inserted. I put 10+ quarters through, each went to hopper, 0 credits added.
-
Been a long time since I've done this. I know there are some test you can do in he menu I just forget how. So do this and I think it will tell us something. The coin optics located right below the comparator ( I'm assuming the plug is attached and you have NO bent pins ) OK do you see a very small White button on the optic board, press it two or three times and with the main door still open, press the spin button, The reels should have spun, if they didn't I'd say there is a better than even bet the coin optic board is bad. If they did spin, remove the comparator and from the top of the optics use a Q tip and knock all the big chunks of dirt off the optics. While you have the Comp. removed look down at the lower part and the encoder ( shimm ) should be of the size that the coin your using should be a tight fit as it passes in front of the optics. If there is no encoder install or say one for a Dollar size coin the coin is going to the hoppper to your left side and the optics are not seeing it as it passes.

Ready for Coin Comp Troubleshooting 101? if not, get ready, because i found a BUNCH of info that will help you! I was just reading some notes I had on Coin Comps from old posts, most likely from Jim (MidWest Slots).
According to my notes, even though I already lied to you and Buzz seconded the idea, if you have no counter weight (or one of the wrong weight, like too light or too heavy), it COULD cause coins to go to the tray! Can you rig up something, even just a short screw, to act as a weight? I'm sure someone can get you one this week, but meanwhile, you may be able to tell if this is the issue. One things for sure, you have nothing to lose by trying it!
Also, one thing that will eliminate everything else EXCEPT the coin comp. is the little button Buzz is talkig about on the optics. Its on the green optics board directly below the coin comp. It is a TINY white push button (I will try and find a pic for you, since it doesn't look like a button, looks more like a little rectangular piece of plastic), with the door open, push this button, it will put credits on the machine (up to the max bet) then pull handle game should operate as normal. If this works every time then everything from the coin optics to the CPU board are working and your problem is with the coin comp. and/or its associated wiring.
The coin comp. works in this fashion: the sample coin you have in the CC establishes a electronic signal. Any coins coming into the CC are compared to that signal, if they match,the rake (coil) is pulsed open for a brief moment and the coin is allowed to pass through the CC into the coin optic and establish a credit. If it doesn't match, the rake is NOT pulsed and the coin is sent to the reject path through the cc and is returned to the coin tray. You can "lie" to the CC and shim out the rake (simulate the rake being pulsed-Opened all the time) if all other circuits are working you should be able to operate and play the game. If this works,then your problem is the CC itself.
One other area that could cause the problem is the woring going into the CC. Check the wires that plug into the CC. Sometimes, from being bent and reinserted so many times, the actual wire is broken inside the insulation. This would prevent voltage from getting to the CC and, of course, then it would not work or work intermittently.

Joey and I discussed these counter weights last week, his commit " I always throw them away "

Great info, thank you. I opened door and pushed the button and it functioned just as you described it. I could press it, it would ding and give me a credit (up to max bet) and then could spin. So the obvious next steps to tackle are to rig up the counter weight and clean the coin optics.
Buzz, thank you for your info as well.
Tomorrow afternoon I'll rig up some type of counter weight system and see if that makes a difference.

1. I would try a different coin,
2. I would remove and reseat the comparitor harness.
- Asking the forum - but the harness can fit on two ways. Does this look correct or should it be reversed ?

Jay I don't know which picture your looking at but the one I posted in #28 works just fine.
