GAME DISABLED - COIN REVERSE
I was getting that message on my EVO. I'm hoping it's common to the Game Maker or other Ballys as well.
Here's all the details... hope this makes sense:

First the bill box wasn't seating properly. I cleaned it, shove it on and the error went way, only to return.
I checked my CC. The entire housing was loose. I tightened it. Below the CC is the optics board. I removed the metal cover and saw the circuit board was about to fall away from the mounting.
I tightened that.
I also turned the sensitivity screw all the way to the left. As I said, only about one of five nickles will go through. I turned it all the way right and none were accepted.
ALSO... when I first removed the cover from the optic board, I noticed the chip inside had the top far right leg squished out of the socket and was pressed against the metal pin of a plug that's just above it to the right. I pulled out the chip, fixed the leg and plugged it back in.
Since I've done this, that error "sort of" went away. It came on last might again, but the message said "open and close door to clear tilt error."
Could the IC leg have caused any problem? It almost looked like it was intentionally left out and made to contact that pin!

Also... the green light on the CC is now off. It was on before. Confusing as heck.

Did you convert this game from one denom to another?

shortrackskater · « **Reply #2 on:** June 28, 2014, 08:08:30 PM »

Nope. It started its life taking nickels and still is a nickel slot. I'm heading to the garage... well maybe a kitchen wine stop first... then to the garage. I'll turn it on and see what it's decided to do.

~~No longer (for now) getting the COIN REVERSE error.~~ The green light on the CC is on when the door is closed...it fades away when door is opened. It's not taking any coins now at all. The optics board has an amber light glowing.
Still getting COIN REVERSE. Now it will happen during a payout... locks up. I have to open and close the main door and it resumes payout.
The coin comparitor sends the coin to the try all the time now.

Ok, first, have you checked what size coin guide it has in it? Just because you think it was always a nickel machine doesnt mean some other guide wasnt swapped in at some time. Just humor me, and double check it and make sure it's not a 25c or dollar guide.

Second, you said you were twisting the sensitivity dial all the way one way then all the way the other. Proper technique I was always told by knagl and stayouttadabunker was to start all the way one direction, then turn 1/4 turn at at time, and check for improvement at each turn.

What's up with the amber light, I have no clue. Not sure if its normally on or not, or what the problem may be.

Dumb question of the day/week/year... where is the guide? Is that in the CC or past? Sorry!
This started happening RIGHT after I straightened that pin and plugged it in properly.

Here's the other error too. I can clear the error... leave the game idle and the error will re-appear.

CVslots · « **Reply #6 on:** June 28, 2014, 10:19:31 PM »

The coin guide is a black plastic thing situated inside if the optics board sandwich (I think that will get you close enough anyway, that's where an IGT is). It's a black plastic piece that should that has "guides" on each side to "guide" the coin to align the coin properly so that it is seen by all the "eyes". A larger coin guide will not "guide" the coins properly so they hit all the optics necessary, thus, generating an error.

Sorry, I don't know Bally that well, but that's the gist of the convo I had with Darrell regarding your problem.

shortrackskater · « **Reply #7 on:** June 28, 2014, 10:31:36 PM »

Got it! I know right where that is... I was just "there." I'll go back and look at the width.

shortrackskater · « **Reply #8 on:** June 28, 2014, 10:37:25 PM »

Here it is...I left the nickel there to show size... a quarter drops right though there no problem. This DID work though for a long time, taking nickels. And the previous owner had it for a few years using nickels.
Update again - One of the wires going to the CC just fell out. I think it was not making contact. I will solder it tomorrow night and report back.

I would think a reverse coin error indicates the machine sensed a coin at the optics then the CC and thinks someone has a nickel on a string. If your CC is faulty or the signal from it is delayed you could get this error possibly. If the problem persists after you fix that wire you might try swapping with a different CC. Sounds like that one has had a few issues so far. Your optics insert should be marked with what size coin it is for. Generally, a quarter insert will work for nickels too

What Coin Comparitor does your machine have? If it is the CC-62 then the problem is most likely the coin guide is set too wide as CV Slots said. Had this same problem with Uni Ultras equipped with the CC-62. The CC-62 senses the coin rattling side to side as it drops.
Even if is not a CC-62, the guide should be only able to accept a nickle.

It's a home use game so turn the sensitivity control completely counterclockwise (left all of the way).

The Amber light on is normal and means the optic board is getting power.

If you are getting "coin in reversed" it means the coin comparator is working and the coin optic board is the problem.

You can try re-seating the big chip on the optic board, other than that you could sent the entire coin in assembly, bracket, comparator, and mounted optic board to Larry to get it fixed. 702-363-9998

Repairing the broken wire did nothing.
CC 16d, 4b
Still getting coin reverse error... it will happen with the machine idle and door open.
Reseated the chip... nothing. Still baffles me that it worked when the top left pin was out of the socket and making contact with the pin above it.
Sensitivity is all the way left.
Why will it work for many plays (using credits) and then go back into COIN REVERSE error?

Badbaud · « **Reply #13 on:** June 29, 2014, 11:20:09 PM »

It could be the plug that plugs into the optic board has some dirty pins or collapsed contacts.

Make sure the pins are clean on both the optic board and the plug that plugs into it.

If the connector is a brown KK-100 type of connector you can slide a thin blade into the exposed window, collapsing the small keeper wing) and slip the pin and wire out of the housing for inspection.

Use a razor blade to bend the pin keeper back out before re-inserting the pin and wire back into the housing.

If the connector is the IDC type where the wire is wedged between two blades on top of the connector you can't remove the pins but you can (slip off the top protective cover if there is one) press each wire deeper into it's two blades to make sure there is a good electrical connection.

Make sure the send and receive optics on the optic board are clean.

If none of that helps your optic board is probably failing randomly, and will soon fail all of the way.

I actually did all that! Thank you though...
I had a spare working cable. I did fix the old one. I can swap that in just to make sure but I'm sure it's working too.
Still wondering... would this cause the random COIN REVERSE error as well?
I guess I should just post a WTB for that board. I'd rather just buy another one than send my stuff out...unless it's some bizarre weird board that no one has... which would not surprise me in the least, at this point!

Badbaud · « **Reply #15 on:** June 29, 2014, 11:30:41 PM »

In my neck of the woods they are very rare.

shortrackskater · « **Reply #16 on:** June 30, 2014, 02:35:48 PM »

I pulled out the optic board again to inspect it and I did get a very slight burn smell. Here's the board. I'll post in WTB as well. I hope someone has this.
Would it make sense for me to also do a clear on the machine and DISABLE the CC to see if my intermittent "coin reverse" error goes away?

Badbaud · « **Reply #17 on:** June 30, 2014, 06:05:19 PM »

Yes, and unplug the optic board.

shortrackskater · « **Reply #18 on:** June 30, 2014, 11:55:30 PM »

I just unplugged the optic board. I've been playing it off and on for an hour, while I put back together my refurbished mpu and suitcase boards into their chassis.
No error... no COIN REVERSE... it just keeps working. I didn't even bother to clear it. Seems to be working fine, other than the occasional yellow screen! (I'll fix this later... I tried de-gaussing)
I think I need an optic board.
I will consult with CV slots.

Thanks for the help Badbaud and everyone else, again.
I see why EVO's aren't so popular... but dammit... I will make this one work!

shortrackskater · « **Reply #19 on:** July 04, 2014, 04:57:51 PM »

Okay this is INTERESTING.
I got the replacement optics board assembly. I installed it and... drum roll... annnnnnnnnnnnnnnnnnd...NOTHING! Still won't take coins.
From the information I got earlier I had assumed the CC was okay.
But just for fun, I removed it and left it connected and then manually let a nickel drop through the guide and the machine DID register it with a new error:
COIN MECH ERROR (something like that).
So I'm thinking maybe the obvious... the CC was bad? Or both the CC and optics board are bad. Tomorrow I'll put the old board back in and try the same test.
Comments?
