41 Code IGT/ Barcrest

[dale]

I have a 2 coin Boulder dash that gave me a 41 code after I pulled the handle. The reels spin slowly and I cannot clear the code with door open and close. I pulled the hopper out to check the wire harness that is a problem in IGTs and found nothing. I put the hopper back in and now have a 3100 code that I cannot clear and the reels are still spinning slowly. This is probably secondary to the 41 code. I believe the SP chip is an 1141. It did have a 64-1 code yesterday but I was able to clear that and get it to play. I have no idea how that was cleared. I am slot challenged and need some help on what to do. Thanks.

I tried a Ram clear and it then stuck on 61-1. I turned it off a couple of times, reset and pushed the test button. I then got a 64-1. I tried what was suggested in a 64-1 topic and disconnected a reel harness. I then got a 49. That would not clear and after off and on, reset key and white test button it is now a 40 code. That suggests a reel motor. Any help is appreciated. Thanks.

Back to a 64-1 code in winner paid window and 40 in credit window. Also no red light, just green. Help.

Still stuck in the 64-1 code. The Top Box Power Supply is mounted behind the reels. I think it is a MPU5. Any suggestions on how to get rid of the 64-1 code? Thanks.

[dale]

I read somewhere that you could switch boards to get rid of the 64-1 code. The board in the Barcrest is a 16meg. All I have are 10meg. Will the 10 possibly work? Thanks.

I was able to find the problem for this code this particular time. It was the connection on the mother board. It was slightly pulled out. Thanks to Kevin for taking some phone time with me. Does anybody know how to turn the Top Box sound down? There is no manual volume control on the MPU5 Game Frame so I need some help. The SP chip is 1141. Thanks.

Dale-

Here's what I have in my notes for how to adjust the top box volume on a S+ Barcrest:

- There must be zero credits on the machine.

- To change the Bonus round volume.......with the door open, flick the jackpot reset key press the self test button until you get a 2-0 ... hit the white reset button several times turn the jackpot reset key until you get to 58.   Hit the SPIN REELS button from 1 ( lowest ) to 10 ( highest) volme.  After choosing a volume; hit the white reset button until all displays are blank and then close the door.....

I can't swear to those being correct as to how to get to it, but I know 58 is the bonus volume setting.  Hopefully that helps you.


Also, written by someone here a while ago:

"I think that what you are going to find even when you get to Option 58 is that no matter what setting (lowest to highest) that you set it to, there will be no appreciable difference in the lowering of the volume in the bonus round as it is supposed to do.  This is an MPU5 anomaly that I've seen over and over.  The only remedy that I have found is to install an in-line rheostat.  Affixed to the back of the coin tray, it is tidy, effective, out of sight and cheaper than marriage counseling!"

For the future, a RAM clear should be your last resort, not the first course of action when your machine runs into a problem.  Glad you got your machine back up and running, though.

I tried that and it didn't seem to make any difference. The machine did go back to a 41 code but I somehow got it working again as the "Open and Close Door" clear didn't work.
Thanks for the reply. A grenade may be the answer........

Actually, I couldn't get the Jackpot Reset Key to go to 2-0. I used the white test button to go to 2-0 then used the jackpot reset key to get to 58. I could use the spin button to go 1 to 5. Did I do something wrong or are the instructions backwards? Thanks.

[dale]

Back to a 41 code after using the handle. Any ideas on how to resolve that problem? It has happened twice. Please help

The instructions are probably backwards -- I was thinking they sounded backwards when I pasted them in here, but I haven't actually adjusted one and I was going off of what I had found in the past.

41 is a reel 1 error.  There's either a bad connection to the reel, or a problem with the reel, (or, but least likely, a problem with the MPU board).  Let's do some troubleshooting.

Unplug reels 1 and 2.  Move reel 1 to the middle position, and move reel 2 to the left position.  Swap the reel stips if you'd like, otherwise the payouts won't be correct (unless your game uses identical strips for reels 1 and 2).

Clear the error.  If the reels are spinning slowly like they were in your original post, open the door, close the door firmly (make sure the latch is all the way down), and turn the jackpot reset key once.  If the reels aren't spinning slowly, the way to clear it is to open and close the door.  Make sure ALL doors are firmly closed (don't forget the door to the cash can).  If/when the error comes back, if it's a 42 error, you know that there's a problem with the physical reel (replace it, the one you moved to the middle).  If it is a 41 error again, you know your reels are working okay and there's a problem with the connection or the MPU board.

I'm also wondering if perhaps you have door sensors that aren't adjusted correctly.  Make sure your cash can is firmly closed and latched (if you don't have a latch, consider taping the switch closed, or shorting the wires together to make the machine think that the door is closed), if there's a belly glass switch, make sure that's adjusted properly, and make sure the optics are correctly mounted and align well when the door is closed.  When the reels spin slowly, that's an indication that the door was opened in mid-spin (or at least, a sensor told the machine that a door was opened).  The fact that you said you got the error most recently after pulling the handle says to me that a vibration caused the reel error, pointing to a loose connection and/or a loose door sensor that got rattled when you pulled the handle.

I think you are right about the doors or cash can door not closed or aligned correctly as the errors occurred during a handle pull. I tried changing reels and there was no change. Fingers crossed it is not the MPU. I noticed the cash can door is very loose so I bent it a bit to tighten it and keep it closed.  I switched optics with a working S+ and they worked in both machines. They reels stopped, the code was still 41 and then I was able to clear it. Not sure what the heck I did but I am just pulling the handle to see if it happens again. My guess is the machine thought a door was open because it would not clear. I appreciate your help and will listen and try every suggestion.

I am slot challenged and do not know how to use multimeters and tech stuff of that sort. I can replace parts.

Oh, BTW any other suggestions on turning the Top Box volume down? The above suggestion did not work. There is NO WAY the wife will allow this machine in the house unless I can quiet it down. I know I can unplug the speakers but the bonus round sounds are fun if they are quiet. The kids like the noise and pulling the handle! The only information that I can give is it is an MPU5, power supply behind the reels and an SP1141.

I'd almost bank on your loose cash can door being the culprit.  Make sure that the door stays closed, as it opening in mid-spin will cause reel errors and/or reels spinning slowly, and it being open will cause you to not be able to clear reel errors.

41,42,43 errors are reel errors.

By moving the reel you have proven that the problem did not follow the reel.
I presume you have made sure there are no obstructions.

I have caused a practically unclearable 41 by opening the door while the game is spinning.
To get past this I ended up having to use a clear chip because following the standard clear instructions did not work.

There is also the possibility that one of the 5 resistors might be burnt out as well.
If you pull the MPU board on the one corner there are 5 resistors all neatly aligned.
is the end one burnt ? if so this will cause the same 41 error.
There are 5 resistors because S+'s can handle up to 5 reels (more than 3 reels is rare).

Thanks for the reply. The board looks fine, as best as I can tell, a slot challenged homeowner. I have tried to recreate the error after making the cash can door tight and have not been able to do so I am thinking it may be solved. I have been playing it this morning with pulling the handle only. I do have my fingers crossed.

If the 41 cleared, use whatever controls you want..... My cash can door does not have a lock so I used duct tape. Its good for about 30 re-tac's
