Hello
I am new here to the site. Thought I would ask if anyone could help me out. I have this bill Accepter DBV-145-PB2-O5OO-A544 It has been working fine for years it takes all the older bills. So. it just started to make a chatter noise or like a relay chattering but when I play the machine the chattering will stop as the reels are turning but when they stop it starts chattering or buzzing noise. I will post photos of the accepter. Also this is in a IGT S+ machine 2 coin 25 cent or bills. Its a hot peppers machine. I would like to fix this bill accepter or maybe it needs a replacement. I'm just not Shure as what I need Any help would be great and if there is any thing more I can answer or give more info please let me know. Thanks so much

Try opening the door.
Look under the coin comparitor.
The coin comparitor is the electromechanical unit that has the "Sample Coin".
There is a small circuit board (Coin-In Optics board) under that which has a small, momentary button on the bottom of it.
That is what you call a "Service Coin" button.
Press it twice, it should put 2 credits on your machine.
Reach around and press the Play button on the button deck, the reels should play one game.
What you're doing is re-enacting what happens as if the machines' door is closed and playing coins for credits.
Check and see if the chattering is coming from the black plastic gate solenoid under the coin-in optics board.
Sometimes the black chip under the gate solenoid goes bad.
It is really a small rectifier chip that changes the AC voltage to DC.
If it goes bad, that makes the gate solenoid "chatter".
Or you can try to pinpoint if the chattering is coming from a little above that, actually from behind the coin comparitor unit.
Behind the coin comparitor is a small, metal coin "rake".
That has a small magnet that gets energized from the coin comparitor circuit board to pull up the "rake" from out of the slot in the coin comparitor - re-directing the coin into another direction.
The magnet has two small gray wires that run to the top of the coin comparitor circuit board.
You can try to wiggle the small white 2-pin Molex connector that has the two gray wires connect to the top of the coin comparitor.
Sometimes the pin connections have a little bit of oxidization on the very pins themselves and make a poor connection that makes the rake "chatter".
However, more often, the "chattering" is really coming from the coin divertor gate solenoid assembly...you'd have to determine whether you can unsolder & swap out the rectifier or change out the solenoid.
The other thing is sometimes the bill acceptor unit gets a little loose.
The bill transport gears on the back bottom of the DBV unit could possibly be out of alignment slightly, grinding really.
Did you move the machine around?
Anyways, there's two brass thumbscrews right in the front of the DBV unit...loosen them a little, pull out the cash box and wiggle the bill acceptor a little.
Hopefully, it will re-seat itself down better, tighten the two brass screws, reinsert the cash box , close the door and see if it will accept a one dollar bill without chattering or grinding.
I'm hoping the chatter goes away just by wiggling the two little gray wires on top of the coin comparitor.
If you find that you're unable to determine what is at fault, I'm sure some of our members here on NLG will have some spare parts to sell to you and get your machine up and running the way you want. :)

Hello
I tried everything you mentioned. Nothing changed. The noise is coming from the bill acceptor.
-
Possibly the power supply has weakened from age?
-
Only thing I can suggest is to disassemble the bill acceptor.
Take it out of there and service it.
You may still have the chattering when you take it out because it could be coming from the handle solenoid behind the bill acceptor.
-
The chattering you're describing really sounds like it's the solenoid for the coin-in rake, but you're the one there, not us.
Can you take a brief video and share it with us so we can see and hear what's happening? That would likely be very helpful. Take the video with your phone, upload it to YouTube, and then post the YouTube link here.

check the plastic gears on the cash can and also the back if the bill accepter make sure none are broken if those are ok than in the back of where the cash can goes into the housing there are 2 tabs that hold up the cash can to the bill accepter , those some time need to be adjusted back up i just slide a flathead screwdriver under each tab and bent them up a little , hope this helps
