Blown fuses, code 61-1, comparitor problems IGT Triple Play S-plus game

[Jim]

Watched you video, here's what's going on!   when you closed the door and put the latch down ,then touched the wires together, you went into the book keeping mode, depending on which SP chip you have it usually will take 7 more times of touching the wires together or some SP's require 12 times.  anyway,  start over, power down the machine.   now power up, door open,  display should have a 61,  press the white test button next to the on/off switch, this should produce a 61_1,  now close and latch the door and now touch the wires together, the display should go blank and hopefully load the program,   if you get a 61 on the machine  then you are in the 61 loop.   try this and see what happens.

You're skipping a step.  Do the following in order:

- Turn the machine on.  Observe 61 is displayed.

- Press and hold the white Self Test button next to the power switch until the machine "dings" and the 61 becomes 61-1.

- Close and fully latch the door.

- Now simulate turning the jackpot reset key by briefly touching the wires from the keyswitch together once, then separate them.

I've done that before but it won't work then. After the "dings" the reset key will not reset the machine. It doesn't do anything.

If the 61-1 doesn't change, the machine isn't seeing the door as closed.  Make sure that the bill validator stacker door ("cash can door") is closed and latched (if equipped), and make sure the main door is closed and the latch is all the way down.

If it still won't advance past 61-1, then your door optics may be bad.

Perhaps the 2 wires that go to the reset switch are disconnected at the other end, or broken inside the wire's insulation? Inspect those 2 wires carefully, follow them back to the other ends of each wire. What color are the reset wires in your machine?

We know his jackpot reset wires are working, as it gets him into bookkeeping data if he touches the wires (turns the keyswitch) when the machine is first turned on.

I'm one step further. The machine starts up with a zero in "coins played"
The problem was in the cash can door. It didn't close. The micro switch was open. Problem solved with some tape because the lock is damaged.


But now I have the following problem. It won't accept coins. The green led in the coin comparitor won't light up.

The various security switches on machines can be a pain. For home use many people remove the 2 wires going to a security switch and connect the wires to each other with a plastic wire nut. The voltage on the wires is low and safe if you happen to touch it, but the bare wires should not touch metal chassis ground. Taping it may work also, as long as the tape doesn't come loose over time when it gets warm.

That is a good solution.

Not sure but I think if you have the machine's front door open the green led on cc won't come on, you can't use that as a troubleshooting help. Does your cc have the sample coin installed correctly? Coin needs to be in the groove or slot on left side of coin holder and the sliding cover needs to be as far left as possible, covering most of the sample coin.

Do the coins just drop straight thru to the coin tray on front of machine? If you press the white pseudo coin button does the machine give a credit?

The wires are light blue  and yellow/green. But why does the reset work on code 61 and not on 61-1 (see my video)? And in the area of the reset key is hanging a lose wire (blue/green)

Yes, that didn't register with me for some reason, the reset switch wires must be ok if the machine is sometimes responding to them.

The other loose wire may be for another function, a photo might help to identify it.

The light on the comparator only lights with the door closed. Set your phone on video and close the door to check. Or remove the coin tray and use a mirror to see. You could have a bad MPU. I have one that is marked "reset key won't work" I remember fooling around with it. Several other boards worked fine just not that one. Not even clearing it helped.

As mentioned above already, you'll pretty much never see that LED lit up, as it only lights up when the machine is ready to accept a coin, and it isn't ready to accept a coin when the front door is open!


- Make sure that the sample coin is seated properly in the Coin Comparator.

- If the Insert Coin lamp is lit and it seems like the machine should be ready to accept a coin, but coins are rejected back to the tray, you'll want to try adjusting the sensitivity on the Coin Comparator so that it is least likely to reject coins:



Using a tiny screwdriver, adjust that counter-clockwise (away from the +) to make the comparator less sensitive -- that will have the comparator reject fewer coins.  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.

Maybe I have to try other coins. It's made for $ 0,25 cents. Well that's what being written on the comparison holder. I saw a small button on one of the connectors of the comparisor. When I push it, I can play with the door open. Must be some kind of testmode ?

That little button that gives you a credit when you push it with the door open is called the "pseudo coin" button and you are right, it is meant for testing. If you press it and get a credit on the machine and can then play a spin that means a lot of things are working, that helps by eliminating a lot of possible sources off the problem.

Can you post a photo of your coin comparitor as it is mounted to the inside of the door?

[yomusic]

I noticed that.   Now I know my machine is almost working as it should be. But when I have a price the speaker sound a "ding" multiple times. And it stops when I use the reset key. No credits are on my meter.
Below a picture of the comparitor. It's a model # CC-160, 24VAC. I use a 0,02 cents euro coin.


Thanks again for the help. I like this forum

From your photo it looks like you do not have the sample coin installed properly in the coin comparitor. The round sliding cover that has the arrow on it should slide to the left to cover most of the coin. That sliding cover is part of the sensor for the coin comparitor, must be over the sample coin. The sliding cover is spring-loaded, you can move it to the right to remove or install a sample coin, but the cover should move back to the left fully so it covers as much of the sample coin as possible. The spring that holds the cover to the left may be missing or disconnected, it is located on the back of the coin comparitor.

The left edge of the sample coin should fit into a groove on that side of the holder for the sample coin. This groove helps holds the coin so that it is stable and is as close to the sliding sensor as possible for best results. Then the sensor/cover slides to the left as far as possible. If your sample coin is thicker than average you may need to loosen the screw in the sliding cover a little so it will move into position over the sample coin.

Notice in the example photos below how the round sliding cover is moved to the left to cover the coin behind it as much as possible:

Here is what the spring looks like on the back of the coin comparitor. Your model might be slightly different but there should be a spring on there.

No quite understanding this statement. If you mean when you have a winning spin you get some ding sounds that is normal operation. If you mean the ding happens when you get a credit by inserting  a coin or pressing the pseudo coin button that is also normal. If you have a large win then the machine may be set for a "handpay" event, like a jackpot event. When that happens you will hear a number of dings and the reset keyswitch must be turned, it is what they do in casino after paying you the jackpot to resume play. This is done because the hopper can only hold a certain number of coins, some jackpots are too large for hopper to completely pay. This payout level where a handpay occurs is one of the settings that you can configure as you wish.

I solved the problem with the coin comparitor. Thanks for the advice. The coin was indeed placed wrong. I also removed the weight in the coin comparitor. The coins jammed on that. Now they fall into the hopper.
But I still see no led light burning on the comparitor. And what is the chrome solenoid on the back on the comparitor with they 2 grey wires for ?


And if I win for instance 2 or 5 credits I don't get them on my winner paid window. In stead of that I have to use the reset key to quit the sound that comes when you hit the jackpot.


Hope you know what I all mean with my following questions. 

[rokgpsman]

...But I still see no led light burning on the comparitor. And what is the chrome solenoid on the back on the comparitor with they 2 grey wires for ?

The led on the coin comparitor will not come on while the door is open. The led is probably for testing purposes on the repair bench or is for some other application. You would have to be inside the machine with the door closed to see the led lit.

The little round chrome weight (called a thumbscrew weight) is designed for a certain weight of coin, you are probably using a different coin than what it was for. It is ok to remove it. The purpose of the thumbscrew weight is casino security, to prevent a player from inserting coins too fast and getting extra playing credits. The weight is attached to a lever that moves into position and slows down the inserted coin no matter how fast you insert the coin.

The solenoid on the back of the comparitor controls a part called the "rake". That chrome you see is part of the rake. If the comparitor accepts the coin that a player inserts then the solenoid pulls the rake out of the way so the coin will pass to the coin optics assembly below the comparitor and then the coin goes to the hopper. But if the player inserts a coin that the comparitor does not accept the rake stays in the way, causes the inserted coin to go to a different path and it is returned to the player coin tray on front of machine.

Be sure you have adjusted the comparitor sensitivity adjustment all the way CCW as mentioned earlier. That will eliminate having some coins rejected when you are playing.

.....And if I win for instance 2 or 5 credits I don't get them on my winner paid window. In stead of that I have to use the reset key to quit the sound that comes when you hit the jackpot.

I think you have a setting wrong on your machine. If the hopper setting or credit limit setting or jackpot setting is wrong then the machine is immediately going into jackpot mode and waits for a casino person to come by to pay you. Do you have any coins in the hopper? Does your "CashOut" button on the front of the machine let you change to credit play (so that any winnings accumulate as credits on the machine instead of immediately being paid)?

There is a white TEST button inside the machine, usually near the power switch. Pressing this TEST button will let you step thru different menu choices and you can enable or disable things. I don't know how to tell you which setting to change but someone else here will be able to.

If I remember right that 731 uses the dipswitches on the MPU. There is a label that explains what turning on/off the dip does.
