Title: Triple Double Diamond slot machine making grinding noise at end of cycle
Post by: Jnickels on February 03, 2024, 10:38:05 PM
Can anyone help determine how to stop grinding noise at the end of the spin? Just started and not sure why. It happens when it is done spinning. I tried to attach 5 sec video but it says it is too large.

Video modified to remove the numerous videos attached in a string! Topic moved to IGT S plus. moderator
Sounds like one of your stepper motors maybe? Stayouttadabunker will reply soon! :yes:

Haha...I have no idea where that sound would becoming from? Is it a mechanical sound byte coming through the speakers, or a physical metal grinding noise from inside the machine? It seems to come right after it's completed a game.
Maybe it's a mechanical counter jammed up? The gears inside a counter housing might be shot.
On the motherboard (long circuit board on the floor), there is a black Molex plug connector in there that has mostly brown wires coming out of that back of it running up to the mechanical counters on the right-hand side cabinet wall above the reel shelf. The plug we're talking about is at location [J5] on the motherboard. In the very center of the black Molex connector, there's a tiny molded tab that you depress, that allows the plug housing to release from the header socket. Push on it and pull out the Molex from the [J5] socket - that will disconnect the counters. Now play a game or two to see if that grinding sound goes away?

It sounds like it has gas! :24:
I wonder if it's the solenoid?
Yes you need to let us know if it's coming from the speaker or the machine.

Sounds like handle solenoid from the timing.

If it's that, fairly easy to check. Just dis-connect the 2-pin black Molex connector on top of the handle mech in the top right-hand back corner underneath the reel shelf. That would dis-able the handle solenoid to see if that's what's causing the noise.

Coin comparator rake coil? Weak cap on camparitor?

What does the coin comparator rake coil look like? That is where the sound comes from

Pull off the CC from the plastic clips and turn it around. On the back is a slot. In the slot is what we call the "rake". It's attached by arm to a magnetic solenoid which is powered by the two gray wires running to the top of the CC circuit board. It'll rattle if there's a bad capacitor on the CC circuit board.
If you want, removed the 2 small Philips screws that secure the solenoid and rake to the CC frame, and dis-connect the 2-pin gray harness from the top of the CC. Save it for another time. Coins will fall thru straight down into the coin-in optic board that's directly underneath the CC. That small coin-in optic board is what registers credits onto the game.
