This is like an arcade style coin comparator!

Thank you for this informative video. I appreciate it.

Thank you bro, My dad slot works great now!!

Thank you so much! This video fixed my issue!

YOU ROCK, thank you.

This was a big help I just got two machines one is from the Sand Vegas casino and the cion mechanism had no labeling whatsoever. So it would not accept quarters. Now I have to sort out how to close the door without the lock someone bored out which allows the door lock mechanism to engage yet not to be opened.

Thanks!!!! Works perfectly

I have a 6000 coin operated us quarter and no indont have a problem with it yet, but I appreciate the video in case the feature it gives me trouble

Behind where the quarter goes in, if you take that out, there is a spring, can you show how that goes on as mine popped out

Question for the slot machine community. I have a Double Diamond IGT machine and I'm having an issue with the 61-1 code. I've done all I can think of to clear the machine with the clear chip and new chips but when I go to turn the reset key the code will not clear. I know the reset key is working because i can change number or codes in the display. I've replace the battery and the door optic with no luck. Any suggestions would be appreciated.

Love the video mate very helpful, just got the exact same machine, do you know how to adjust machine settings on these? Volume pay out rates etc? and or know of somewhere that is a good resource?

I tried all this and quarters are still dropping into coin tray? What can be issue?

Quick question since I have run out of options...I have an early 90's 3 reel wild cherry slot machine that was handed down by my grandfather. There are no error codes but the coin just drop through when we go to play. I have a feeling it is missing a coin comparitor...my machine does not have the one like your machine. It doesn't have anything where the coin drops through. Do all of the early 90's machine have them?

My IGT s2000 Double Diamond slot only ejects a paper win ticket...How do I change it to drop the winning coins instead? Thanks for posting your videos!

I think you should not leave it there. You moved it all the way counter-clockwise to where it will accept the maximum with fewest rejects. That defeats a lot of the purpose of the COMPARATOR function! You should now re-open the machine and keep making small adjustments clockwise until the machine starts to reject coins. Keep some odd mangled and/or dirty coins on hand for this as well. Ideally, you should also have a brand new uncirculated coin in the comparator as the coin it's searching for. Once you have the machine to the point where it is just starting to reject the mangled/dirty coins, go ahead and turn it counter-clockwise in very tiny increments until it finally accepts the legit-but-worn coins again. And once you get it to that spot, that's the spot you want. That's the IDEAL spot. You're not telling them how to find the ideal setting, you're just showing them how to de-activate some of the features of the coin comparator.

Quick question, My Ballys Double Diamond has the same coin comparator and I'm having an issue where it is humming loud! but, only when I have a coin in the comparator & slot door is closed, If I take the coin out and shut the door the hum is gone ... I've tried cleaning the coin comparator, Didn't work ... Any advice would be helpful.

should the little green light be on or not dose it matter

Is that a flat head or philips screwdriver you are using to set the sensitivity. It is so small I think I may have stripped it.

I have a double diamond 25 cent slot machine, quarter works but the bill validation doesn't work? How can I fixed the issue?

Hello Knagl and hello everyone. I have a somewhat specific question to ask. A million years ago, I was given a Taito slot machine, which is nowhere to be found now. It looks a lot like to Pachislo models, with 3 real rollers equipped with a stepper motor. The model is Space Invaders. Since his coin acceptor had given problems, when it was replaced identically the software on start-up detected the change and asked for an 8-digit password to be entered. However this password is the result of a password generated by the slot. It basically spits out an 8-digit password and asks for another to be entered. I ask you if you know which software generates an 8-digit password compared to 8 digits given by the software. Thanks so much to anyone who can help me🙏
