Service Light Door open error

[tmiron]

I spliced (jumped) both the case optical sensor and the door optical sensor - furthermore did the same with the coin door and drop door switches - both not effecting the blinking light - was looking for a good wiring diagram to trace back the plug or chip that is causing the issue.

Also both the door switch and drop door test correctly in the self test which adds to the mystery thx Tim

From one of Jims posts....in another thread.
Did you check the door optics test in menu 10_1,   scroll to #13 close the door and see if the 1 toggles to a zero and back and forth, if not optics not working (or bypassed), machine will never work until this works.
If you bypassed this should be a solid 1. 

If the Insert Coin light is not on the bill validator won't work as the machine is not ready to accept coin or credit.
In addition - its very likely that you will need a SET chip to enable the bill validator so we can leave this issue until after we get the machine accepting coins.
- A SET chip tells the slot how many credits to get for a buck. Ie Setting the machine for 0.25 allows 4 coins for a dollar. This doesn't impact your self tests just won't work in production.

Hello went to self test and it does go to from 13_0 to 13_1 and from 31_0 to 31_1 for the drop door

However there is no test for the cash door do you know how to test that?

Thank you Tim

[Stayouttadabunker]

There isn't a test for the cash door.
Physically check with a multimeter.

Try this...>>>
Watch the [Coins Played] window on the display as you move the door latch downwards until it is fully at the bottom of slot in the door.
Does the number momentarily go off and then come back on at any time?
If so, then the problem is that the door emitter or cabinet receiver optics are misaligned.
If you want to learn how to align them...ask and I will tell you how to line them up with a pencil and two pieces of masking tape.

I noticed something in your photo in Reply #10.
The machine is powered up but there's nothing being in the display at all.
Are your three reels stiff with resistance when the machine is powered up and the door is open?

Also, how exactly did you perform the 13-0, 13-1 door optics test when you've said that they're been bypassed?

Finally, is the bulb/lamp behind the [Insert Coin] display window good?
That lamp WILL come on IF the door is in a "closed state" - either bypassed or physically closed.

Hello,

I don’t have door optics - they are bypassed as I mentioned in my last post - need a wiring diagram with color codes to try and find the cash drawer wires - it has to be the coin door - thank you

[jay]

To Marks point if the optics are bypassed 13-0 13-1 will not work.
They would be a steady 13-1 (closed).

[tmiron]

Interesting development you were correct I did output test number 41 and the “insert coin” lamp was in fact burnt out - in reference to how I performed the input tests I removed the bypass and put it back on-

FYI if I use “service credits” little white button the game functions perfectly

However coins are still going right through to the hopper

Thanks for all of your help - where do I go from here

[jay]

Do you have a sample coin in your coin comparator ?

[tmiron]

Now if the machine is registering that the door is closed - although can’t test the coin door

Shouldn’t the coin comparer light be on?

Thank you

[jay]

I don't see a sample coin in that comparator.
Slide the part back that is labeled - Slide and put in a quarter.

[tmiron]

Hello there is a nickel in the comparer - it is a nickel machine also the bill receptor is not lighting up that light tested good in tests - thanks Tim

[jay]

Per my earlier post.
You will likely need to get a SET chip to enable the bill validator. Especially if you ran a clear chip through the machine.

The S+ is a credit machine.
You put a coin in, you get 1 credit.
It doesn't matter what coin ... as long as the coin in the comparator matches what you drop in you get 1 credit.
The machine does not know what kind of coin you put in there. When you hit a winning combo for 15 coins - the machine either gives you 15 credits or 15 coins spew out of the hopper.
You will note the glass doesn't say You will win $3.75 (15 x 0.25) or 0.75 (15 x 0.05) it says 15 coins.

SO....

When you put a bill in the bill validator how many credits do you get for a buck ?
Clearly the slot doesn't know what kind of coins it uses...

This is where the SET chip comes in.
You SET the machine to be 0.05 so when you put in your $1.00 you get 20 credits.

So while the bill validator might have tested good.... until you use your SET chip its not going to light up and take any bills because it doesn't know how many credits to give.

On the NLG home page - bottom right hand side you will find RICKS FAQs and there is a section on using the SET chip to enable your bill validator.

Try removing your nickle and putting a different one in there. See if the results are any different.

Hello I am unable to play a paid game -

I am able to play with “service credits” but I am dumbfounded why it still is blinking

The light is still blinking because you have not completed a paid game. Try not to focus on the light right now, let's focus on getting the machine to accept a coin.

I would strongly recommend hooking up a known good set of door optics. These machines were not designed to have the optics bypassed.

[Stayouttadabunker]

One of the other possible reasons the coin-in optics isn't "seeing" a nickel drop thru to register as credits to the machine, is because the encoder coin guide inside the coin-in optics might be the one sized for a quarter.
If this is true, the nickel misses one or more of the ABC optics, and doesn't register a credit.

Look at the two different encoders in the photos below.
The three holes in the encoders are for the infrared light beams of the emitters and receivers in the coin-in optics.
The encoder guides is sandwiched in between the optic boards just beneath the coin comparitor.
Yours might be the top encoder which is made for larger coins than the smaller nickel that you're using.
The one I'm showing you in the photo is actually made for those larger casino tokens...which are even bigger in diameter than a quarter!
The bottom encoder guide has that little wedge to make a smaller coin move over to the left.
That makes the smaller coins like your nickels, slide OVER the holes to momentarily block the emitter light beam, and register a credit to the MPU.

The front board of the coin-in optic boards has the Service Coin button that you've used already.
That button ONLY works when the door is in an Open State and the door optics are NOT "seeing" each other, or inoperable.
Also, the LED light on the coin comparitor will not be on.

Although you state that it's a nickel machine, it may be possible that all they did was change the label sticker on the reel glass.
They may not have changed the encoder guide as they were supposed to, the deck coin slot, the wheel hopper shelf plate, or set the denomination with a SET015 chip for .05 cents.

Also, as many have stated earlier, you MUST get the door optics working correctly for the coin comparitor LED light to come on to accept coins AND have the correct encoder guides so the machine registers credits.
Finally, I hate to say it but when you bypassed the door optics, if you crossed the wires even once incorrectly, you may have burned out the emitter or receiver IC components on the MPU board, and it may never work again - even with a good set of optics.
If you've bypassed it correctly, the LED light on the coin comparitor should be on...if not, I will gander a guess that you've fried something on the MPU board or cooked the emitter optic itself.
Put the door emitter optic back on and view it with a digital camera to see if it lights up.
You can also try moving the lamp from the denomination socket on thereel glass display board into the [Insert Coin] socket for now, until you get yourself some new bulbs.
The [Insert Coin] lamp lights up as well - when the door optics are in a closed state.

[Jim]

please explain how you bypassed the door optics?  what are you using to simulate the opening and closing of the door.

if you feel the optics are working as they should, and you can operate the machine with the coin optics switch, then your problem is either the coin optics or the cc-16.

remove the surface mount transistor Q-2 or Q-4 from the coin optics board, this may solve your coin in issue. or shim out the rake on the cc-16 and see if it will allow the coin to go through and establish credit.  or give you a code 21.

After all the chip clears - I managed to break off the legs of the game chip so ordered new ones - will fill you all in in about a week - thanks to all of your thus far / Thanks Tim

[tmiron]

Hello - Got my replacement chips and the slot is still not accepting coins or bills. I made some videos for clarification- thank you

[sixcardmark]

Did you test the coin-in ABC optics?  Did you try shimming the CC rake so it can't reject coins? 

[tmiron]

Just did a b c successfully

Blocked the rake with paper and now gives me 21 error

[Stayouttadabunker]

OMG!
You did NOT jump the door optics correctly! You wired them together?!?!?!
That's like wiring a battery together! Positive with a negative?
That MPU could be finished!
Who in the world told you to wire the door optics together like that?

Your only chance to get that board working again is to get a long piece of wire.
Take the PURPLE wire from the door emitter harness end and connect it all the way over to the cabinet receiver optics' RED wire on that harness end.
Leave the black and green wires alone and unconnected!
If this works, the LED light on the coin comparitor will come ON and you'll be able to accept nickels although they may be wrong for the encoder sandwiched in between the coin-in optic boards.
Also, the zero in the [Coins Played] on the reel glass display will momentarily go out and may change to a different number.
