IGT Coral reef slot machine error code 3100

[tom14]

The problem is that with the hopper in I can not get the 3100 error to clear and as soon as you put a coin in it kicks one out. With the hopper out I can get the 3100 error to clear. Could there be a problem with the hopper. Anything else to look at to try and get this fixed.

Can you put the hopper on a bench and  take the bowl off the hopper?

I want to see a coin that you're using sitting on top of the knife as it goes through the hopper optics.

Hold one hand on the brakes or put a rubber band around the whole motor and turn the hopper by the agitator with your other hand.

Let's see a coin go over the knife and through the optics.

Also, I want to see behind the hopper optics and see what kind of optics and wiring are being used.

I also want to see the wiring going from the hopper to the beau plug and see if they are connected to the beau plug pins correctly.

When I turn the wheel of the hopper the coin goes on top of the knife and through the optics.
Here are some pic's of the hopper, part number of the optics, and a couple of the wiring and the plug.

Also this all started after I had to replace the battery and the machine got stuck in the 61_1 loop and had to use clear chip to get the machine running again. Before that everything was working great.

Have you considered running the clear again ?

[tom14]

I did do the clear a second time, however if you think it would be a good idea to do it again I am willing to try it.  I do have another igt slot machine it is the Double hearts are the hoppers interchangeable, if so would it be a good idea to try swapping them.

[sixcardmark]

Yes if it is also a s+ try swapping hoppers.

[Stayouttadabunker]

I agree with SCM...swap the hoppers!
We didn't know you had another one to try.
If the suspect hopper doesn't work in the other machine and the other hopper works in this cabinet, we'll know it's the suspect hopper.
Your wires look good....everything is connected okay and in the right locations.
You took great photos.

Remember, after you perform a clear, you should give the machine a denomination value such as .25cents or $1.00 or whatever you want...but the machine should have a value in the [0-6] page and make sure coins act as going to credits rather than to game.

[tom14]

Ok, I will try swapping them and see what happens.  It will be a couple of hours before I can get to it. I will let everyone know what happen after I swap the hoppers.

[tom14]

I swapped the hoppers and the coral reef machine still does the same thing and the hopper that was in the coral reef worked just fine in the other machine, so its not the hopper. so much for the easy fix,  any ideas.

Could there be something wrong with one of the boards? If its one of the boards is there a way to test them. If its one of the boards any ideas on how I could get it fixed or replaced?
Should I try to do the clear again?

The machine works fine with the hopper out. I don't know what to check next or have anywhere to take it to be fixed.

Thanks
Tom.

The next step would be to swap MPU boards.
The reels and payouts won’t line up unless you swap them also but this is really just a test.

[Stayouttadabunker]

You need to put that Clear chip away...
The only time you would really need it is when the machine is stuck in the [61-1] error code.

The suspect hopper worked fine in the other cabinet.
That RULES OUT the hopper - there's nothing wrong with them.
We're trying to zero in on the problem.

Swap the MPU's as Jay said above...throw in any hopper, try putting in a token, then report back and we'll give you next troubleshooting instructions.

[tom14]

I am going to try and swap the MPU boards in the morning have to be up early. I will post a pic's of the boards in the morning before I swap them around, maybe y'all will see something that I don't. Will I get any error codes by swapping the MPU boards, if so should I follow the flip cards for clearing the error codes?

Thanks for all of the help so far.
Tom.

I am pretty sure you will get a 61 error because the game chip is different in each.
The 61 will become a 61-1 but you won't get stuck in the loop.




Given that the hopper is known to be good, I think we might be looking at a MPU board issue.

Unlike a mechanical hopper not much electronically is observable from the pictures but I think a picture of the battery area is relevant as you swapped that out. If you take the board out of the tray a picture of the back of the board would be relevant.


While you have both MPU boards out - compare the battery areas and see if you perhaps notice any solder runs that might be shorting on the one board. 


Fixed tiny font issue.  -knagl

What does the fine print after "...MPU board issue." say Jay? lol

[jay]

It was the browser on the phone..... hate when that happens....




As they say the devil is in the details....... Here is what I attempted to write.......

Ok, I pulled out the MPU boards and put the coral reef board into the double hearts machine, got the error that Jay said that I would get and it cleared just fine, however once I got it up and running I got the same problem.

So it looks like it is the coral reef MPU board. Is there any way to find out what went bad on the board or will it have to be replaced?

Attached are two pic's one of the board and one of the battery area, (could have done a little better on the solider) but it doesn't look like anything is touching that's not suppose to.

Thanks
Tom.

[jay]

What about the underside ?

[tom14]

 Here you go. Sorry about that I forgot to put that one in my bad. If you need another angle let me know.
Thanks again
Tom.

So with the coral reef mpu board and either hopper in the double heats machine when I  turn on the machine it automatically gives you the extra coin paid out error (3100). If I power it up with the hopper out and then put the hopper in and put a coin in it kicks out one coin and gives the 3100 error. As for the mpu board the underside looks ok. I don't know what the other board is call the the mpu board plugs into. I just got to thinking if that board has a problem would it cause something the mpu board to be damaged, if so i realy don't want to put the Double  hearts mpu board into the corsl reef machine.
Is there a way to check the other board in the coral reef machine to make sure that it is good, I don't want to find out that the other board is bad by messing up the mpu board from the other machine.

[Stayouttadabunker]

"I don't know what the other board is call the the mpu board plugs into"
The MPU plugs down into the motherboard.

Power down, remove MPU and carefully re-seat both SS and SP chips.It may help.
