S+ Not Accepting Coins or Bills..

Do you think both the coin comparitor and optics board could be bad ?

[stayouttadabunker]

You're half right poppo,
But the coins have to go through the coin-in optics first before
they get diverted to the drop or the hopper.
To get to the tray, the rake isn't opening upstairs.

jacell,
I'd try a different set of optics or cut off the Q2 chip on the con-in optics board 1st.
Here's a link on how to do it>>>

If your coins are dropping to the tray, the coin comparator is bad.
The rake doesn't open to let the coin go down to the coin-in optics.
If the coins are dropping to the hopper or the drop, the coin-in optics are bad.
That's when you can cut off the Q2 to register a credit.

I will try cutting off the Q2 chip and let you know what happens..I have it apart so i want to cut the Q4 which looks like a small black box..Wow i need to find something small to cut that out with.

[stayouttadabunker]

You can use the tip of a sharp knife to pry it off the board.

Bunker,  the optics have nothing to do with the diverter.  the diverter gets its signal from the brass hopper probe that is mounted on the bowl of the hopper. the hopper chassis is at ground potential, as the coins  accumulate in the hopper bowl they eventually will pass the ground to the probe because they are metal as well. the logic board puts a ground to the diverter bridge rectifier  to produce a dc voltage to energize the coil which in turn will mechanically move the gate to deflect all the overflow coins into the chute to be directed into the machine base.

Ok, now I am confused. But I am just going by what I have read before. I thought first, it passes through the comparator. If it passes that test, the rake opens and it then goes to the optics to be counted. If it doesn't pass the comparator, the rake does not open and it drops to the tray.

In this case, early on, he bypassed the rake, but it still did not get counted. Now that the rake is back to normal, they are dropping to the tray again. So would that not indicate that something in the comparator circuit is not working? Not to say the optics don't also have a problem, since bypassing the rake did not help.

I guess I'm just thinking that there is something else wrong causing both not to work. I suppose at this point there is no harm in trying the optics mod, but I am skeptical that it will help. And won't he have to bypass the rake again anyway?

[Jim]

No    the optics are doing both things, shutting down the cc16, and not allowing the optics to see the three signals necessary to register a credit.

the cc16 will operate as it should, the mod has no visible affects on the game or any other functions.  there is a slim chance that the cc16 could be bad, however you won't know until the optics are working correctly.

[Jacell3]

Yeah it works.... You guys are great .Thank You
 I have one more request.... If you would be able to help me on the other machine i have.

[stayouttadabunker]

Here's a short clip I hope will help.

I'm suspecting that the coin-in optics will register credits once he does the Q2 mod.
The rake may still need to be propped open with paper or whatever.
I'm not sure if his coin comparator is working or not. >>>

Glad to hear that! 
Is your rake propped open or is it normal?
If it's normal, then it should have allowed the quarter to drop into the
hopper or coin drop all along - rather than the tray.
By the way, the coin "Drop" is the hole that goes beneath the machine into a bucket.

Anyways, once the coin passes the coin-in optics, it cannot get to the tray.

Start a new thread for your other machine under the appropriate forum heading...

[Jacell3]

I still have the rake propped open...I took the paper out and the coins fall to the tray

[stayouttadabunker]

ah...that explains why the coin comparator was really warm!
An IC component controlling the rake solenoid on the CC board was ffrying out...!

Keep the paper in to prop the rake open or
remove the rake w/solenoid completely with two screws.

[Jacell3]

Ok i will do just that...Thank you guys so much
Now i can have some fun

So there were two issues at work here -- 1, the comparator was (and still is) incorrectly rejecting coins to the tray, and 2, the optics needed the Q2 component snipped.

Problem 2 has been resolved, but problem 1 remains.  You should not have to prop the rake open with a piece of paper for a slot to work.  In addition, now ANY coin dropped in there (provided it's large enough to break the optics) will register a credit, and later jam the hopper.  If you have a $0.25 machine, you shouldn't be able to drop pennies into it to get credits, and I suspect that's exactly what can happen right now.

If after trying to adjust the comparator sensitivity again you still can't get coins past the (un-altered) comparator, you're going to want to buy a replacement.

[Jacell3]

Yes that is exactly what happens it pretty much accepts any coin now...I will be on the look out for a coin comparitor and an optics to correct the problem...At least now i can have fun at the moment playing... Thanks so much for your help.

Your not going to find a optic any better than the one you now have. If you have some money burning a hole in your pocket, you can always donate it to    In your quest for a comparator look for a CC 16 D 24 Volt.

[Jacell3]

I did donate this morning to NLG...It was so worth it...Thanks for all the help and knowledge from you all.

[knagl]

Indeed, your optics are fine (you fixed them!) -- you juse need a new comparator.

[Buzz]

 For future reference: the cc16 does one thing in the S+. it compares metal discs. if it sees a match, it pulses the rake open for a brief time to allow the good coin to pass, if no match then the coin is rejected. Very simple. how it compares the metal discs is a little more complex, simply stated: the sample coin establishes a electronic field, if the incoming coin sets up the same field, then a null is produced and the unit will pulse the rake open and allow the coin to pass.

Jim

Jim This was the most interesting statement you made. I never stopped to think about how and what the comparator was reading. I think I always assumed it was reading the thickness, metal content and the diamenter of the sample coin. The diamenter doesn't have a thing to do with it, does it ??  Thanks
