GAME DISABLED - COIN REVERSE...cash box? coin comparitor? karma?

[shortrackskater]

 Hang on...

Had to delete the last post here and re-write it.
There's just no rhyme or reason to this. I made the shim... reinstalled all and then all coins were dropping to the hopper and not being registered at all!
Took it all apart again... made sure it was aligned... same thing.
Swapped out the chip with my spare "possibly working" other COD board... same thing.
Removed my shim... reinstalled... same damn thing... no coins registered... just dropping in.
Fussed again... made sure it was exactly as it should be, comparing it to the other COD unit (with frame). Reinstalled it but I had taking the shim out... now it's working again!
This machine is beyond my brain capabilities. I did get it from being completely dead to "almost fully" working but the frustration is making me drink!

Okay I just "fabricated" this out of two layers of foam tape stuck to the plastic COD coin optic thing.

yes you have a 25cent guide that  what is  wrong I had same trouble

From your first picture I can see the spacing was to wide and that is why you were getting errors.

The spacer you installed looks much better but foam tape is sticky and could slow down the coin.

Find a hard piece of plastic to make the wedge.

Badbaud - did you know you helped me with this same issue extensively? Just scroll back to page 1, 2...
I thought it was determined that the 5 and 25 cent guide were the same size? Mine still seems big to me.
I'll try making a wedge again that won't cause any friction to the coin.

I cut up a plastic stick-on wire tie mount. It fit right in. I played a while...working so far. I removed the jam from the rake and it's still good so far.
I feel like I've been here before though.

Well good news and bad news...
So far I haven't got any COIN REVERSE type errors. But... it once again began dropping some coins through, but just to the tray. At the same time, I notice the touch screen stops responding too. This happened before, a long time ago. I have no idea if there's any connection.
I re-wedged the CC. I cleaned the screen, for the hundredth time.
Working again.
It's listed on Craigslist too. Problem is I don't want to sell it to anyone who doesn't know what an EVO is. It's just not right.

[Badbaud]

It may be time for the shotgun approach.

Re-seat every connector in the machine, unplug it and plug it back in a couple of times.

A freezing screen could indicate a computer board problem or a dirty connector, let's hope it is the latter.

[shortrackskater]

Okay did all the above, again! So far, it's working. Once in a great while, the CRT turns more yellow! I can just tap it and it stops.
I'm just running out of the will and energy to keep working on this machine.
In my few years of collection slots, I've fixed a LOT of IGT s plus's, s2000's, CEI poker, Status poker, and even my Bally Game Maker. But NOTHING has been as strange and obscure as this machine! It has been FUN (believe it or not) getting this up and running but it wasn't easy.
And I TOTALLY APPRECIATE all the help from  badbaud, CV slots, cowboygames, uniman,  and the rest!
With that said... I'm done with this machine. I posted a WTS here. I hope someone close to me want's it and can figure out the last "oddities" in this slot.

 This was a very entertaining repair topic,
 It looks to me that if a .05 guide was purchased from the beginning this could have been handled in a timely manner....
 Where would a person find a Nickel guide? I just purchased a Bally Game Maker with similar problem and I believe the guide is a Quarter guide and would like to replace it.

Correct me if I am wrong but I think the nickle and quarter guides are the same size.

[mantaramian]

I was wondering the same thing.... that's why I put up the Post...

Thanks

[buybestslots]

Correct me if I am wrong but I think the nickle and quarter guides are the same size.

if the coin can bounce or go  thur and miss a eye it will at times go into coin reverse I had some nickel games  that a quarter wouldn't fit thur  the coin guide , so I think there is a 5cent   and a different one for 25 cents for ballys , we have made dollars ones work with a 25cent coin  by add screws inside the guide to   make coins stay to one side and past all eyes

[mantaramian]

 Once again thank you for the response, I will let you know how it works out over the weekend....
 Happy Holliday’s,

I agree with bestbuyslots. I think there's a different one for nickles. I had purchased a replacement guide and optics and the same thing happened. I just made a shim using an adhesive wire tie mount, cut to size. So far I've had no "reverse coin" errors at all.

Happy New Year 2015

So after reviewing the configuration of my recent purchased Bally 19" LCD Game Maker I seen that it was configured without the COD, So I performed a RAM CLEAR and configured the game with the setting obtained in this post.

The coin in reverse message went away after the correct configuration, but the game would not recognize the coin when dropped in. Yes, the bill acceptor works but the coins would go straight in the hopper.

That's not right, so I pulled the coin comparator out and found a piece of cardboard holding the rake in to accept all coins...

Bottom line, the coin comparator was bad and the machine was configured incorrect....

NEW comparator and RAM CLEAR and all is well....

Thank you for all your time and wisdom...

THANKS mantaramian!
That really makes me think I have another bad CC as well. It only makes sense. And just because I got it "working" on ebay doesn't mean it really was!
I did have to jam my rake for it to work. I still get an occasional coin dropping to the tray but mine works fine otherwise.
What model CC is in your machine?

[CVslots]

Woohoo!! Good job!

[mantaramian]

2 pics, something else to mention. I don't believe the Bad Comparitor is the correct one to use either

• Bad Comparitor

• Good Comparitor

[Badbaud]

Green wires to the coil means it is a DC comparator - grey and it is a AC comparator.

If the grey one works then the machine generates a AC voltage for the coin lockout engaged signal (ready to accept coins) or if a comparator is used it powers up the comparator to compare coins dropped to the one lodged between the sensor coils.
