CC 16 Problems on IGT DDD

[jliken]

Hello all,

I am new here and have tried many of the recommendations found in other posts.  Still not working so here goes:

Double Diamond Deluxe IGT S+ machine with cc 16 c coin mech (no bills)

Coins go to Hopper without registering.

I cleaned the optics and adjusted the potentiometer (but coin was never rejected to tray).  Performed system self test function and shows optics working.

LED on cc is on when door is closed.

Not sure where to go from here?

Thanks in advance for taking time to look at this.

Wiggle the two gray wires on top of the coin comparator,
close the door, and try some coins.
Could be an oxidized pin.
If that doesn't work, remove the coin comparator, turn it around
and see if the rake is wedged open with something.
It should move freely.
Also, change the comparator coin with a new one similar to the ones you're using.

Basic adjustment for the sensitivity dial on the CC is :
Turn dial counter clock-wise fully to the left until stop.
Turn it clock-wise about a 1/4 turn.

[jliken]

No luck with that.  They continue to drop to the hopper.

In your top photo, the coin mech harness is not plugged into the door harness.
Is it still that way?

Probably not now...
anyways, it sounds like you coin-in optic board under the CC are not registering credits to the machine.

Two things can cause this:

1] There's a black plastic coin guide sandwiched between the two boards.
Sometimes these don't have the plastic guide inside in the middle because the machine used large tokens at the casino before it was taken out.
Or sometimes they break off.
Without the piece of guide in it, the quarters slip by the three holes in the plastic insert and miss the optics - thereby not registering any credits.
You need to remove the CC and stick a piece of cardboard straight down that slot in between the coin-in optic boards that is about 1 inch wide.
If the cardboard does not go down and through, then you have the guide.
If the cardboard goes through, you have the wrong insert for quarters and need to get a new one or use larger tokens as your machine may be already set for it.


Below is a "Coin Decoder" as Suzo-Happs Controls or IGT calls them...sized for quarters.
I borrowed this photo from Yoeddy's post a while back..
I lost my photos...

the other thing that can cause this:
2] The coin-in optic boards might be at the end of their life.
You can extend the life of these boards (for home use only) by cutting off the diode located at the Q2 position on the optic board.

There are ways to run tests for all of which I've mentioned above to trouble shoot your coin-in optics and coin acceptance.
This is enough for now to try.

see 1st though, if you have the correct coin guide sized for quarters - if that's what you're using.

Not directly related to the problem, but one quick test to see if the rake is working or has been tied back is to remove the sample coin and see if the coin drops to the tray.

I agree with bunker that it may not have the right insert. Did the machine ever work?

Aslo, it may just be the picture, but the optics look crooked or something. Are the coins actually dropping through it?

[stayouttadabunker]

You see that too?!
I thought it was my screen or something...
Yeah...somethings NOT lined up right...could be obstructing the solenoid gate cam.

[jliken]

Rake is free.  Nothing binding there.  I removed all and re aligned the optics panel.  I have the quarter guide, but my board looks different.  Not sure that I have the same diode.  Everything is hooked up for operation, so if you see anything unplugged, it is because I don't know where it goes....  Thanks for your time and expertise.

Just curious, you said the CC LED was on when the door was closed. How did you check it? I ask because I recall another recent thread where there was an issue with some game chips doing something strange when using a door bypass. Also did the game ever work? If so, did something change before it quit?

[stayouttadabunker]

The Q2 is on the other side of your photo of your optic board.
Two screws removed... will reveal that.

The LED light on the CC is indeed "On" when then door is closed.
You can view it through the door lock hole if there's no lock installed.
or you can view it by pulling out the CC through the belly door.

I quote from Jim on a thread back in July '09 on testing coin-in optics...>>>

...you can test these in the machine using the first three tests  of the inputs test.  Reassemble the optic using the metal frame along with a black coin in optic guide. then cut a piece of cardboard about 1/4 inch by six inches. when you call up that test  10-0   when you pass the cardboard thru the optic you should see the 0 change to a 1 telling you that optic is good, advance to 11-0  do the same and also press the little button down in the lower left corner and it should produce the same results, finally advance to test 12-0  and run the cardboard thru again and see the 0 change to a 1. this will test all the optics and let you know if they are good.

Right. I was just curious as to which method was used. Specifically if this machine has a bypass.

[stayouttadabunker]

The only problem I ever had with the bypass cable was when I was trying to clear a [61] with certain chips.
I had to install working optics to get by it for that one time.
I think it was when we were playing with the Army chips?

I have owned this machine for about 8 years and has worked flawlessly until a few months ago when it stopped registering the coin in.  No real issue because I had over 2000 credits on it, until yesterday when I changed a setting during the self test procedure.  No more credits, so machine is "dead in the water". 

I pulled the tray and sent the cc through the belly to see the led.

Input test 10-1 - I swear that this tested fine yesterday.  Today, I am not seeing a change to 0.  This is a door closed test isn't it?  Proper guidance here would be appreciated.

Input test 11-1 - 1 changes to a 0 when cardboard is passed through,  Same for test 12-1

[stayouttadabunker]

No.
The door needs to be open to run the coin-in tests.
What SP chip is installed?

[poppo]

What did you change? Do you still have the credits?

If you don't (or even if you do) you might try pulling the CMOS chip for a few seconds. You will get a 61, but it will reload data from the eeprom in the off chance that soemthing got screwed up in the CMOS. Plus it will check your door optics as they will need to be working to clear the 61.

[jliken]

I changed values in test 7 & 8.  When I played my credits and had first win, payout went fast (but no coins dumped) and all credits were gone 

next problem - I don't have (actually cant find) the key to get to the processor board.  I will work on punching the lock next.

[stayouttadabunker]

That's strange...you can't change the settings in the options when you have credits on the machine...
Normally, the "Credits" window display must be zeroed out in order to make changes.

[jliken]

Leave it to me to find a way!

[stayouttadabunker]

I am trying to re-enact your problem with mine.
I will try to change options 7 & 8 (BTW which are for the coin limits) with credits on my meter.
Offhand, I do not think I'll succeed.

Again, what SP chip do you have on the MPU...?
you can check by hitting the little white test button 9 times to bring up the alternating SS and SP chip numbers
in the Credits display window.

ADD>>> I just tried to change the settings with 3 credits on my display.
I cannot change anything.
I made a short video clip...
my battery died so it will be a few minutes before I get it up on here.
Just re-charging the battery enough to save it.

[jliken]

It is an SP-872  

Yes, I was changing the coin limits so that I could reconnect my payout button.  Too many times people come into the house and "accidentally" push the cash out to "see what happens".  I probably screwed that up too!  

[stayouttadabunker]

Sorry, not seeing that.  If I hit button 9 times, it counts up by even numbers on displays. 

I can't see anything on your machine from my house either...I have no idea what you mean by this...


You're the 1st slot homeowner I've heard who has a lock on the MPU cage...
Maybe you ought to bust that lock on the MPU...it's made for casinos really.
After the Ron Harris affair, everybody started putting locks and motion sensors on these cages...
paranoid bunch of casino owners...

When you get in, see if you can report back what SP chip is installed in the "Game Prom" socket.

Here's the short video I was making for you when the battery died on me...>>>

[jliken]

Thanks for the video.  That is the way it is supposed to work.  What can I say.  I changed them by going thru the same process you did when you played off your 3 credits. 

Lock problem solved.  No lock anymore.  cmos removed and reinstalled.  How do I clear the 61?  I already tried holding in the self test button.

[stayouttadabunker]

Pressing the white test button 3 seconds is all that's needed to get to [61-1]
At that point, you close the door then turn the reset key once.

Since you've already tried that...install a clear chip in the place of the SP chip.
The settings are still on the chip on the motherboard at the moment.
You have a SET chip ready to re-enable the DBV?

BTW what were you trying to change originally?
The hopper limits or the... nevermind....I still don't know what SP you have so I cannot help much further.

[jliken]

Ah, turn the reset...... that was what I was missing.  All clear now.  Coins still dropping to hopper and not registering....

clear chip and SET chip, DBV - you have now officially gone "over my head" or should I say past my level of in- expertice!

I slipped the SP in above.  It is a 872
