Coin dropping through IGT PE+

[agordon117]

Hey everyone, first post here.  I have an IGT PE+ that I'm working on, and have run into an issue that I'm not sure how to fix.  First problem was a bad screen, replaced it with the ceronix LCD replacement.  That works fine.  Next problem, now that I can see the machine is working, is that coins are dropping through.  Here's what I know after looking at other posts here and just general troubleshooting. 

add credit button works
bill acceptor works, proving that the machine plays just fine
blue coil in the belly door is cracked, is this attached to the coin diverter? 

I've attached a picture of the blue coil that's cracked (forgot to take a picture of my own), and I've included a picture of my coin comparator. 

Could this blue coil be the issue?  If so, where can I find a replacement?  Normally I'm pretty good at finding these parts, but I must not be hitting on the right search term for this component.

Hello, that is a coin comparator and it has a quarter set in it which means it only accepts coins that match the size and weight of the sample coin.  You can this by turning the potentiometer on the lower right that has the plus and minus indicators all the way to the left towards minus which makes it less sensitive. now it should let nearly any coin that is remotely close to a quarter to be accepted. If it does not work then we need to look at other options such as making sure the machine is set up correctly. Do you know if the machine ever accepted coins?

That blue solenoid isn't a part of the comparator though is it? 

The machine accepted coins once upon a time, but it only gets occasional use and probably hadn't been used in 5 years or so.  At that time it did accept coins. 

I did try turning down the sensitivity, it didn't change anything.  I suspect that the diverter isn't flipping when the comparator says to accept a coin.  Which I suspect is related to the cracked blue solenoid (crack isn't shown, first picture is shown for identification purposes).  That's the main question I'm trying to ask.  Does that solenoid divert the coin, and where do I get a new one?

The vendors on the home page can probably help you out with a diverter solenoid. Call don't use their websites.
Many people just wire tie these back.

The diverter coil doesn't have anything to do with accepting or rejecting a coin.  It takes the coins that have been accepted and allows them to drop into the hopper (de-energized) or diverts them to the overflow tube which would go to a bucket in the bottom of the machine stand.  That happens when the hopper is full or has reached a level determined by what hole the brass hopper full screw is installed in. 

The rake on the back of the comparitor is what either allows the coin to fall through the optics if the coin meets the sample coin characteristics, or deflects it to the coin tray if it does not.

We need to look at what the LEDs on the comparator are doing. We also need someone familiar with PE+ initialization who can tell us how we know if the device is activated.

As a side note I turn those diverters off by removing a wire, they almost always start buzzing. Be sure to insulate the exposed wire.

Lets start with the basics.

1. Do you have a sample coin in the comparator - what denomination is it ?  You may want to swap it for a different coin. Sometimes a coin sitting in a comparator for a long period of time has its metal properties shift just enough that it doesn't register. Happens more commonly with Tokens.

2. What model of comparator do you have ? CC-16D ??


3. Under the comparator is a optic board. Look closely - very closely - there should be a tiny (super tiny) button on this. With the door open press that button and it should put a test credit on the machine. Which you can play with the door open.

We know the machine is activated because the bill acceptor works and the game plays fine with that.

1: I did change the sample coin.  It's a quarter. 

2: the picture is of my comparator, it says CC-16-D-VAC-R1

3: The test credit button works fine, machine plays normally when adding credits that way.

Per the BV - thats great news.

With the door open if you push the large white test button you will get to a screen that you can do some coin in tests.

Can you post a picture of your coin-comparitor - specifically the harness.
If you do a Cell phone pic - the image will be too large to upload but if you mail it to yourself you will get the option to reduce size, and then post that image.

This is helpful.  So the comparator assembly itself has the moving piece that allows the coin to be accepted or fall through?

The coin comparitor only compares coins.
If they match the "Sample Coin", the magnetic coil behind the CC gets energized, and pulls the rake.
The rake behind the CC gets pulled in, and allows the coin to slip by the rake - falling straight down into the coin-in optics below.
If the coin doesn't match the Sample Coin, the rake stays still, and re-directs the coin out to the side chute, and back into the coin tray.
The coin comparitor does NOT register coins as credit...it's the coin-in optics board underneath the CC does that job with the ABC optical eyes.

Try this if you're just using quarters at home...>>>

Remove the coin comparitor (CC).
Wiggle off the small 2-pin gray harness from the top of the circuit board of the CC.
Push the two gray wires thru the hole in the metal comparitor frame out the back of it.
Take off the 2 small Philips screws that secure the rake magnet to the CC frame.
Save the magnetic coil, and rake for some other time...you do NOT need it.

Now, install the CC unit back onto the plastic clips.
Put back on the comparitor's 6-pin white Molex main connector harness.
Wire colors should be a red loop on top, purple wire in between, a yellow wire, skip one hole, then bottom black wire.
Close the door.

From now on, all coins the size of a quarter or smaller, will fall directly into the CC, thru and down into the coin-in optics board underneath it.
Coins falling thru between the coin-in optical eyes should get registered back to the machine, as credits.
Hope ths helps?

Correct. We first need to determine if the CC is working at all. That’s why you want to test the credit button, it will tell us if the CC is passing information to the game board.
One thing at a time. After we get the CC to accept a coin you can start disabling solenoids if you wish.
I will examine pictures when I’m on a bigger screen to see if the lights are correct.

Yes. The rake on the back of the comparitor is the physical component that moves to either let the coin pass into the optics if accepted, or kick it to the coin tray if rejected.

Gotcha on the solenoid behind the CC.
I haven’t seen or been told that the light on the CC is turned on or if the credit button works.
