Machine has quit working. Upon power application: 14 in Winner paid; 1024 in Credits and Cash/Credit button all flash about 3 seconds followed by a 41 error in winner paid. Reels never attempt to turn. Lower candle blinks rapidly with upper blinking about once a second. This machine has worked great for years. Any help appreciated

41 error is reel #1. Try swapping reel 1 and reel 2, if error moves to 42 check that reel, if you still get error 41 check the harness.

Make sure nothing is touching the reel - I once had a bit of scotch tape come loose from a reel and it just barely rubbed on the glass and I got an error 43. (3rd reel).

Clear the error and see if comes back.

The candle is basically telling you that there's a tilt and the door is open.
If you close the door, does the lower half of the candle stop flashing?

Swapped reels, no change. Can't see the harness suddenly going bad as haven't been inside machine messing with anything. The Candle still flashes as stated with the door closed. Could it be the reel eprom for the game?

sixcardmark · « **Reply #5 on:** July 20, 2023, 09:20:41 AM »

After opening the door the candle will continue to flash until after you have played a game.

jay · « **Reply #6 on:** July 20, 2023, 10:18:07 AM »

Did you clear the 41 error ?
If you just moved the reel opened/closed the error will remain.
and obviously with an error you can't play a game
and if you can't play a game - the candle won't change its behavior.

Here is a quick video on how to clear the reel tilt

Followed the video, My reset is not on the MPU but next to the PWR button. I reset it and 41 goes away, but soon as I close the door it goes through the same sequence and back to a 41 error. This is regardless of which reel ia sitting in number 1 position. This is the only IGT machine I have. Not well versed on troubleshooting this machine. All my others are Ballys.

That video was a S2000 machine, you have a S+ machine. Well you ruled out it being the reel. Are you sure nothing on the inside of door or wires to the left side of reel are rubbing reel #1?

jay · « **Reply #9 on:** July 20, 2023, 01:32:24 PM »

Sorry about the S2K vs S+ but you cleared it and that is the main thing.

Look at your MPU board.
Top left corner has 5 resistors on it. The first 3 should show some scorching and the other 2 pristine.
The S+ could be a 5 reel machine but we rarely see anything other than 3 in North America.
Each one of those resistors represent a reel.
Using a meter set to Ohms (resistance) test each resistor.
Is R1 dead (completely open) and the others showing resistance at some common value ?

If so you could move R5 to R1 (no need to worry about leaving a resistor in R4 or R5).

Reel 1 is clear of any obstructions. Will ohm out the resistors and see what they read. Thanks for the advise

Stayouttadabunker · « **Reply #11 on:** July 21, 2023, 05:23:12 AM »

I'd swap reel connectors underneath between #1 with #2, then close the door - to see if the problem follows reel #1.
It could also help if you blow the dust off of the reel optics that read the encoders on the hubs.

I believe the resistors that hold the reels in position or "stiff"are 10k?
I outlined them in red for ya.

Swapped the connectors and blew off the reel optics, no change. Dumb question. I assume that I will have to desolder resistors from the board in order to get resistance readings. Otherwise they all read infinite.

jay · « **Reply #13 on:** July 21, 2023, 01:01:03 PM »

That is mostly incorrect.

IF you set your meter to Ohms (Resistance) and hold the two probes apart you will get a 0 (or infinite) because there is no continuity. If you touch them together you will get a 1 showing 100% continuity.
If you had a disconnected resistor you put a probe at each end and you would get a measure of the resistance across the resistor. Ie 10,000 ohms (10k).

When you have a 10k resistor in circuit and you measure across it you may get a inaccurate reading like 7k but unless its a bad resistor you won't get a 0 (open/infinite).

So without you digging out your soldering iron you should be able to measure across each resistor - the conjecture is that each of the resistors should give you the same reading (accurate or not). However it should not give you a reading of 0 unless the resistor is bad. With an error code of 41 - the hypothesis is that resistor 1 is going to be way different than the others.

If they are all the same ten we can rule this out as your problem. There is also reel driver chips that we can look at after we rule out that the resistors are good.

Jay
you were right. Lowered my scale and all 5 read approximately same resisitance value. So we can now assume that is not the problem. Where to next?

jay · « **Reply #15 on:** July 21, 2023, 02:45:26 PM »

You have just exhausted my level of competency - we will need some of the other guys to jump in here.

Albeit you might want to see Rick Hunters post about the reel driver chips in this thread.

On S+ the reels should spin with the door open. Thus how we use the psuedo credit button. What is happening on the front door? Insert coin light on? When you close the door, do the displays go blank for a few seconds? If not it is not seeing the door as closed. Check optics for broken wire. If they do go blank, then reels try to spin, then error again? I spent 15 minutes checking a coin-in error only to realize it was 21 credits on the machine. Take a couple pictures for us

OldGuy · « **Reply #17 on:** July 21, 2023, 05:48:05 PM »

Here you go Elvis.
First pix door closed and everything blank, only hear relay click once
2nd Pix this display clicks 3 times and then goes to a 41

therockinelvis · « **Reply #18 on:** July 21, 2023, 05:59:43 PM »

What do you mean by click? The reels trying to spin? With the door open press the pseudo coin button under the coin comparator. If it ding and adds a credit press the spin button to see what the reels do

OldGuy · « **Reply #19 on:** July 21, 2023, 06:33:45 PM »

By click, I mean as the displays as seen in Pix 2 flash on and off there is a distinct noise that can be heard similar to a relay opening and closing until it goes to 41. I did not see a pseudo coin button under my comparator. My reels do not try to spin.
