igt 41 error please help

[Koni]

I hope somone can help me. I have an IGT double red white & blue. It came off a cruise ship and I am told it was a "S" machine that was converted to an (S+) with a conversion kit. It is a smaller machine. I cannot get past the error 41. Here is what I have done so far. New processer board, new mother board, new reel harness. I have done a clear and when I check the reels in test mode the 40 (reel one ) does not toggle even after I swaped the reels. The test for reels two and three pass the test and toggle. When I fire up the machine after a clear I get a 61 then I press the test switch and get a 61-1 then I close the door and turn the reset key. The 61-1 clears and all three reels spin 1/4 turn and stop. This happens 4 times and I get a 41 error. I have had both of the boards tested in another machine and they work fine. Any ideas.
Thanks- Koni

Check the (white)plastic molex plug that connects to reel #1.  also pull the reel and check the molex connector underneath the reel.  perhaps a "pin"  has been pushed back.

koni,
Are you only getting the code "41" or are you also receiving codes being either "42" or "43"?


ADD>> I agree with cp if you are only getting code "41", meaning somethings wrong with either wiring, connectors going to that first , leftmost reel.
Try switching reels , to see if the errors travel with where you switch.

[Koni]

I installed a new reel harness and also moved the reels to see if the error would follow and it did not. I am not getting a 42 or 43 error just a 41 not matter which reel is in location one.
Thanks- Koni

[Koni]

I still get a 41 when I switch the reels and a new harness??? Thanks- Koni

OK,
code "41" ONLY , means this....you better sit down, it might hurt, the first reel resistor on the MPU board could be done.
It's a pack of 5 resistors down on the bottom right of the MPU board. The first one is for the "41" reel (or the left most reel)
the 2nd is for the (42) middle reel, the 3rd is for the (43) rightmost reel. IGT added two more for the future in case they wanted to make a five reel machine.
The good news is this, would you have a spare MPU board? Pull your SP and SS chips and install them on the other MPU board and you should be good to go.
MPU boards for sale from idylewild are very cheap at the moment as I'm typing this.
It's always nice to have a spare MPU by the way.

I just replaced both boards that I sent out and had them tested. The 41 was comming up on the old boards as well. When the boards were tested they were both fine and the test machine fired up and worked. - Koni

If he's getting a 41 error, the machine isn't going to get to the point of a 42 or 43, even if there are problems with the second and third reels -- it needs to pass the reel 1 test first.  These things can't show multiple errors at once.

Koni- Do the reels spin at all when you first power on the machine?  If not, are you able to put the physical reels in a different machine to test them and make sure they're good?  I'd still suspect a connection problem with the first reel, either at the molex connector under the reel, or possibly as it makes its way back to the MPU.

[Koni]

Knagl, When I power up the machine it has the 41. When I close the door after about 10 secs all the reels jump about a quarter turn at the same time and they do this 4 times then the 41 comes back. It also does this when I switch the reels do different positions. When in the reel test mode I cannot get the first wheel to toggle. The other reels do toggle with the test. Thanks- Koni

See if you can get the 3rd reel to toggle if you only switch the first molex connector from reel 1 to reel 3.
Knowing that we are going to get an error "41" but , now to see if we get the error when you toggle the 3rd reel.

In other words, switch the harness between 1 and 3 to see if the problem moves to the 3rd reel when toggled.
Leave the reel physically in the same place...only move the harness to find the problem.

[Koni]

I actually did that yesterday. I did it 4 times by switching the harness to different reels and never got the first reel test to toggle. It did not matter which reel the number one harness was on I could not get the physical first reel to toggle. The other two did toggle even with different positioned harnesses.

if the MPU boards are good, the reels are good, then it HAS to be the harness itself.
If the harness is good, then it could be the reel chip eprom.
Do other reel chip (SS) eproms work on this MPU board?

Finally, the motherboard itself (the one that on the floor)
is it a S+ motherbaord, or an S motherboard?

An older S motherboard will not work properly with an S+ MPU.
There should be some etched print right on the motherboard itself , stating whether it's an S or S+ motherboard.

[Koni]

As far as I know the chips are also good. I just got the board back from Ben at Fannini Slots and he said the board tested fine when he put it in another working machine. The only thing he did was set the dim switches and put a zip tie on the battery. He thinks there may be a short somewhere in the wiring. This machine has been a nightmare, I have been working on it for over a month now. By the way I see you are a fellow golfer. I am the Club manager at Conestoga Country Club in Lancaster Pa. Just 3 months and we will be playing warm again!! Thanks for your help I will check back with you tommorow. - Koni

I'm dying to try out my new driver at the Malone golf club this spring... ...anyways, this isn't the golf channel...

I still suspect the pins in the molex of the harness, a bad ground wire on the input test wire, or something on the MPU...or some bad connection somehow on the the motherboard on the floor under the MPU. Did a coin sneak under the motherboard, perhaps?

How about this then, does the reels do that funny 1/4 spin when the door is open or when the door is closed?
If it does it when the door is closed, then it (the 1st reel black plastic basket oval) may be touching the back edge of the credit display board that's right behind the reel glass. Check to see if there's any rubbing evidence on the back of the display panel.
This CAN possibly happen if the reel apparatus isn't fully pushed back into the reel - tray slots far enough.

This may be off the wall, but I'm wondering if a complete clear is in order. Could corruption of the EEPROM on the motherboard cause problems like this?

[Koni]

I cannot find any markings on the motherboard that say an (s) or (s+). The only markings I see is the copyright "1986", Assy or p/n # "7590390" and n-2v.0. How can I tell what type it is?- Thanks- Koni

I have tried all suggestions, still getting a 41. Could this be a short in the wring? If so which harness's shoud I check and how? Thanks- Koni

A 41 indicates that the first reel is in error. These can be a pain to clear.
I struggled with one for quite a few days until I changed my game chip from a 1271 to the older 731. This gave me some other errors 65-3, followed  by a 65-1 and finally a 65-1.
When I cahnged back to the 1271 it worked just fine.

If you think this IS a physical problem move the reel basket to another position if the problem moves then its the reel basket.
                                                             

[Koni]

The game chip on the board now is a sp731 which tested fine on another machine. I don't have any other game chips to try. I do have a clear which I did and I also have a test 123 which I tried as well. The 41 error does not follow the reel baskets when I change them. Any other ideas? Thamks - Koni

It is starting to sound like the reel harness has a loose connection or broken wire.

[Koni]

Foster, I replaced the reel harness as well. Thanks - Koni

If you have tested the motherboard then time to check the reel harness for a loose connection or broken wire.

 S machines usually had the board mounted in the back of the machine,with three plugs going into the logic board,two on top and one on the right side  no mother board. S+  has the card cage mounted on left side (if no dbv)  ,sounds like you have a S+ intermediate size versus wide body. Most of the time depending on the fault,you can still enter the diagonistic mode and cycle thru all your tests. If you can do this call up the program pay table test and run------see if you can get the reels to run in this test. if nothing else we will eliminate the reel problem in the service mode and perhaps isolate it to the play mode-------   always like a challenge   have plenty of  S+ machines in house to test sub assemblies   have many relatives in Lancaster   was from Minersville,Pa.  originally

Perhaps posting some pics of the inside of the machine, board and harness would help.

Good luck,
