Hello All!!! Long-time visitor, first-time poster...
I Recently acquired an IGT S+ Haywire (3coin, $.05). All functions perfectly except all coins drop directly into the tray. I assume the comparitor is not working as it should. A friend of mine who spent many years in the industry has a long wire that will connect the door sensors to see the comparitor with the door open-- no light at all. I have replaced the short (7-8 inch) wiring harness to no avail. It's a beautiful machine but the boss says it can't come into the house until fully functional. Getting cold here in central Illinois... Am I missing an easy fix or is buying a replacement my only option?
I had no idea of the wealth of information or the expertise on this site. I cant find anyone in Illinois that works on or repairs slot machines. Thanks again and I look forward to making NLG a daily stop on my browser.

If the machine use to take coins and now does not , you can try the following. Change the coin that is in the comparitor. If still not working, turn the sensitivity pot fully CCW. If that does not work you can pull out the circuit board in the comparitor and replace the cap on the board.
-
#1. It should two gray wires coming from the top of the CC card to the magnetic rake behind it.
If they're green, then you need a new coin comparitor.
#2. Turn the sensitivity potentiometer dial fully CCW as Sunrise Side said, but then turn it CW a 1/4 turn to accept quarters.
Stick a fresh quarter in there behind the coin holder "slide" then close the door and try it.
#3. Cut off the Q2 from the CC board, re-install and try dropping quarters in.
#4. Give the boss a few bucks, the key to the car, and tell her to go shopping for a nice, comfy chair to sit in when she wants to play the machine. :rotfl:
PS....can you post a picture of that repair you did to the harness?
I want to see close ups of both ends. :sherlock:

Make sure that the reels are stiff when powered up - if they are not then you have a different problem than the comparator/coin in.
You can check the function of the machine by pressing the door small micro switch on the coin optics to give it a credit with the door open.
The game should play when you do this (door open of course). These test credits go away when the door is closed.
Which brings me to the next point. The other common reason that a slot wont take coins is that the door optics are not working.
If the test credit didn't clear and the reels spin once when the door is closed - it likely means your door optics are not working.
Check the alignment and make sure they are matching up. There is an emitter and receiver - one is mounted on the cabinet and the other on the door.
You can also use a digital camera / cell camera to see if the emitter is flashing. Its Infrared light which cannot be seen by the naked eye but a camera will show this as a beaconing/flashing light.

Thanks for the insight. Here are my most recent results of your suggestions.
1. The CC that was in the game had green wires, which I assume is the wrong voltage. It has been replaced with a CC-16 with the GRAY wires.
2. I replaced the entire 6-8 inch wiring harness from the CC with new from Ebay.
3. The microswitch gives credits, reels spin, credits are awarded and paid by the hopper with the door open. When the door is closed, the credits clear and the reels return to their standby position.
4. I do NOT see any pulsing or flashing lights emitting from either end of the door optics. I received new (to me) optics and will be replacing them this evening.
Again, this is a 5-cent machine with NO bill acceptor. Thank you all for your insight, Ill keep you posted.

OK I have replaced the door optics and still no change. I cannot tell if the optics are working or properly aligned. What is the best way to do this? I cannot see any flashing with a digital camera. We're so close but I can't get this last problem resolved. Thanks again

Normally I place them centered on their respective brackets and hand tighten the pair of screws that secure them there.
Just don't go crazy over tightening the screws.
That usually gets them lined up pretty close.
Stick a piece of masking tape on the door and on the cabinet near the optics, side-by-side vertically.
Open the door and draw a line on the tape where the height of the receiver optic is.
Also draw a line where the emitter optic is on the other piece of tape.
Close the door with the door latch fully downwards as far as it will go and the two lines will tell you how far off they are.
Make adjustments to optics on their brackets.
Another way to tell is to play with the height of the door latch.
Gently go up and down while watching the [Coins Played] display.
It should go out momentarily as the optics pass and /or "see" each other.
The emitter optic should always be installed on the door and has red and black wires.
The receiver optic should always be installed on the right wall of the cabinet and has red and white wires

Hello Again. Now I have LOTS of spare time so I'm back at it.
1. :1: :1: I did the tape thing. The optics line up correctly.
2. The test credits do indeed disappear when I close and lock the door. The reels then return[/size] to stand by mode (from right to left). 3. Coins (nickels) simply fall right through into the tray. Any other suggestions are appreciated. I will try to post some pics this afternoon thanks again
-
in your reply #4, item #3 pretty much indicates that the optics are working, ( the credits wouldn't disappear and the reels wouldn't make their maiden spin if it didn't see the door closed!)
try this test : http://newlifegames.com/nlg/index.php?topic=14723.0 (http://newlifegames.com/nlg/index.php?topic=14723.0) this will tell us if the coin optics are working,
on the back side of the coin comp is a magnet coil ( the two gray wires go to it) you will see a spring near the magnet, pushing that spring down will cause the "rake" to be removed from the inside of the coin comp, this is the part you want to shim out, keep it from going into the housing (use a small piece of cardboard to do this) now try and see what happens when you close the door and insert a coin.
three things could be wrong here, a bad cc-16, bad coin optic, or bad cpu board or associated wiring, ( after a game play, the board sends a signal to turn on the cc-16,noted by the LED coming on.
we will get you up and running.

You need a digital camera that has a CCD sensor on it, the cmos censors do not see the blinking lights for some reason.

Hello again
Shimming the rake allows the coins to drop directly into the tray, but no coins register.
10-1, 11-1, and 12-1 tests all work, switching from 0 to 1 and back
The black plastic guide behind the coin optics board says "5c" which is also correct.
What to look at next?
-
Into the coin tray or the hopper?
-
SORRY. :CaptainHappy_worried: Shimming the rake puts the nickels into the HOPPER.
Now after I hooked everything back up and powered on, the display shows "21". Going backwards i feel.
-
With the door open, press the "Service Coin" button switch a couple of times and let us know if it adds a couple of credits to the machine.
Press the spin button with the door open.
Let us know if the "Service Coin" button is adding credits at all.
Show me a few pictures of the coin in optics, and your harness....front and back.
Take your time and photograph good pictures.
Something I think is wrong with your wiring harness or something else like Jim said.
The gate solenoid isn't opening and coins aren't registering.
We'll figure it out....there's never been an S+ I couldn't get repaired in my life.
Are you able to disassemble the coin-in optics from the bracket?
I'll bet ya the black plastic guide inside isn't made for nickels either.
Every time you throw in a small nickel, the nickel keeps missing the "B" optic of the A,B,C optics - that event would cause a [21] error code.
Just for kicks, slide out the nickel on the coin comparitor and install a quarter in there, close the door and drop a quarter i and see what happens.
-
The coin comparator sends a vend pulse to the coin optic board firing the "A" optic detect then as the coin passes through the coin optic board optics "B" and "C" are blocked by the coin giving a valid coin in.
With the door open you can press the pseudo coin button on the coin optic board and just the "B" optic is toggled giving you a door open coin in to play the game with door open.
Sooo, you could have a bad comparator not sending out the "A" optic toggle, if that is present and you still get a 20 code then your "B" or "C" optic or the chips related to it on the coin optic board is defective.
-
Badbaud, would turning the potentiometer sensitivity dial too far clockwise shut off the "B" optic too?
-
Badbaud and Stayoutadabunker
When i close and lock the machine, error 21 shows up and the reels do not return to standby.
The black plastic guide behind the board is made for nickels. A quarter will not fit through it.
Is there a way I can provide you with pictures and video other than on this post? My files are WAY too big.
If you want to provide an email address or phone number I can get you all these pics.

Thank you.

Thank you.
WAY BETTER if you simply reduce your file size and post them here. Someone in the future may benefit from this thread.

To make your pictures smaller - first email them to yourself from your phone. You are then promoted to make the pictures smaller, these then can be posted.
If you press the white button multiple times you will cycle through back to the beginning and the error should clear after you close the door.
-
you should be able to clear the 21 code by closing the door and latching the lock bar all the way down, this should clear it and spin the reels on their maiden spin, if not then the machine is not seeing the door closed.
code 21 usually appears when something isn't right with the coin optics, wiring or ? double check all your connections.
you stated this in your last reply, reels didn't spin to reset position.

Another way to post a video is to upload it to youtube and paste the link from the youtube video to a Reply here.
okay....the coin-in guide is made for nickels...I'm glad you checked it out.
When you close the door, the door optics are working because the "Coins Played" display goes out momentarily then comes back on when the door latch is fully depressed right?
We need to know for sure if your door optics are working but you say the reels aren't moving after closing the door.
Try this, move the reels to a different position by hand before closing the door.
If the door optics are working, the reels will spin back to the position of wherever they were before.
Also, were you able to add credits by the "pseudo" or "Service Credit" button on the coin-in optics w/the door open?
-
Reels will not return to stand by after moving them manually.
Error 21 remains.
I have removed all components, checked connections, and reinstalled. Same result.
I cannot add credits from the micro switch.
I have also depressed the white test button to run through all options and the error 21 persists.
-
Are there any specifics i need to know about different comparators? I have three all different.
one has green wires
one has gray wires
one has gray wires with an additional small tab next to the rake.
See pic
-
I explained that in Reply #2....do not use the green wired one.
In Reply #4, you said the "Service Credit" button on the coin-in optics gave credits to the machine w/the door opened....now you're saying it doesn't?
You're starting to confuse us.
Retrace all steps you've done since then and get the coin-in optics to give credits again.
Check the coin harness fully and make sure every pin is connected to every component of the coin unit.
Check the pins going to rake, the gate solenoid, the coin-in optics, the coin comparitor.
Look for a broken connection on the wiring right behind the Molex housings where the wire and
its wire covering go into the back end of each pin on each housing.
Particularly, I would like to see a photo of the harness with the Molex housing and pins that go onto the coin-in optics and the CC.
On those two grey wired coin comparitors, remove the 4 screws that hold the front cover and snap some photos of the circuit boards.
I want to see if you're using the right ones.
In the picture I posted below, remove the anti-string device on the left CC, you don't need it for home use.
I marked it with a red "X"
Take a sip of that beer and be patient...we'll figure it out. lol
Click on photo to enlarge if needed...>>>

Yes. I have discarded the green-wired one.
Yes. I can no longer get service credits since the 21 showed up.
I will now open up the comparators and provide pictures soon.
I am as confused as you are. It used to be a coin comparator issue but now i cant get through the 21.
i will upload pics of the inside of the comparators this afternoon. Thanks for your patience. :wave:
-
The code [21] is popping up because something isn't connected or the door optics aren't working.
The [21] code will NOT go away until both are fixed and operational.
Pull apart your Molex connectors around that whole coin unit, inspect the pins and replug back together.
There's round male pins and round female receptor pins.
Check if any are bent, folded over or opened too much.
When you plug them back together, you can always check for continuity with a multimeter on both ends of the Molex housings.
But it's better to check from further back at the end of the harness to the other side of a connection.
When repairing these machines, the use of a multi-meter comes very handy in looking for bad connections.
I don't have my documentation here at home, maybe Jim can you some insight as to which pins to check for power with a multi-meter to the coin-in optics and CC.
Your harness is the main suspect right now.....check your fuses on the power supply too.
-
Well, here I am again. As of tomorrow I'm on unpaid furlough so ill have LOTS of time to get this Haywire resolved. :(
Still in error 21, all Molex connections look good.
Are there instructions on how to use the multimeter to check connections? everything went fine as I recall until i removed and replaced the small, credit card sized board on the coin optic next to the comparator.
Thank you again guys
-
Take out the harness, place on table in front you.Set multimeter for continuity, test pins from both ends for continuity.
Give me model number of your multimeter, I can find instructions for you.Or post a picture of it.
