I would be interested in to see if the behaviour changed with a 1271 game chip.

It would also be good to swap in a known good MPU (containing any game) just to see if the problem follows the chassis.  Is there anyone that can lend Save a spare for test purposes.

I am no expert on self tests..... but Are they working properly
- it seems to sit at 0... more than 1 .... I think it should be alternating between the two evenly.... Kevin / Mark ... perhaps chime in here.

Tough to tell with the LED flicker from the video. I'd say if the machine is operating normally when just the play credit/spin reels buttons are used, we can presume that the optics are generally working well. He's only having the issue when the handle is pulled, as far as I know.

After removing a lot of what it could be I am back to the same question, when the door is closed, latched why is the pull handle unlocked and the lower candle light flashing. The game does play and function, except for the handle being unlocked, light flashing.

The pull handle unlocks when the game is idle and there are credits on the machine or if a coin has been inserted, to allow the player to pull the handle. It would normally be locked if there are no credits on the machine and if no coins have been inserted. I presume the handle would also lock when the door has been opened, as you can't spin a paid game when the door is open. Basically, the handle should be unlocked when the Spin Reels button lamp is lit.

As far as the flashing lights, you can do some of your own investigative work to learn what some of the candle light flashes mean on your machine with the GAME (SP) chip you have in use. While the printed sheet you have is a good general reference, the SP chip is what handles that and the lights can vary slightly depending on the SP chip in use (ie. the printed sheet of paper may not always be 100% accurate as behavior can vary by chip).

For the following, use only your Spin Reels button (and not the pull handle since you're having intermittent trouble with it): I would suggest completing a paid game, and then observe the machine. There should be no lights lit on the candle. Open the door and observe what the candle shows (I suspect the lower lamp in the candle will flash rapidly indicating that the door is open). You can check the handle too and I believe it will be locked. Now, close and latch the door and observe what happens. The LED display on the front of the machine should go blank for a second or so, the reels may re-spin back to the result of the last paid game, and the lower candle lamp either will turn off, or it will remain flashing rapidly until the next paid game is completed. If that candle light is still flashing, go ahead and spin a paid game. You should now see the candle lamp turn off. Does that help to understand at least partially what the candle lights are telling you?


From your earlier video, the issue still appears to be that sometimes when you're pulling the handle, the machine believes for a second that the door has been opened and then closed. The first hypothesis was that it was due to a vibration from the physical movement and stop of the handle causing the optics to vibrate out of alignment momentarily. It seems though, based on your testing, that such a vibration may not be the case? If so, I would suggest looking for possible pinched wires, or anything that could be shorting together or shorting to ground when you pull the handle. Are there any wires getting pinched or moved around near the handle mechanism inside the machine when you pull the handle?

Just like stayoutofthebunker, I have printed this out and will go through it.
I will process this information, and get you some answers.
Thanks for everything, I am getting a better understanding of the IGT slot machine.
I can access all of the programming, which is really important.

So far every machine i know of that had that card in it was fam14 im currently converting 2 of them to family 20. Those brain boxes and pci cards are extremely hard to find. When they go up for sale they sell quick. Most the time the only way to get one is to buy a machine that was converted.

The Brainboxes are rather common, but the PCIe card is not. You have two of these cards?

haha...you found my youtube channel 
The pictures of the power Molex to the motherboard in Reply #223, is also a photo I took - to try to help somebody.

I listened to you playing with the door latch in your video...I can tell from the sounds when you opened or closed the door latch.
The sounds correspond with what the display is showing [13-0] or [13-1].
From that, I would definitely say that your door optics are functioning fine.
What we really don't know is whether or not you able to introduce door optic malfunctions on purpose by jiggling the pull handle - as Knagl and Jay have pointed out.
Knagl's suggestions of checking for pinched wiring, is what I'd be checking.

I'd watch the [13-0] display as I move around wiring harnesses.
I kind of hate doing that because you know the fragility of the optic anode and cathode connections but really, there's nothing else you can do to check if they're partially broken or not because of the vinyl wire covering hiding things.
They also put small black shrink-wrap over the connections too but that's not where I think they're broken....I believe if anything is partially broken, it would be where the anode and cathodes enter the body of the T0-46 cans of the optics.
Those metal cans were very fragile.... that's why I recommend the newer plastic emitter & receivers.
The anodes and cathodes of the newer plastic optics are molded into the plastic.... they're much stronger?

Oh...the other day, I almost made another video for you of the door handle being unlocked when in "Service Credit" mode, with the door in an opened state.
I forgot and now I do not remember offhand, if there needed to be Service credits on the machine or not, for the handle solenoid to unlock the handle.
You can verify this yourself pretty easily...I, on the other hand, am nowhere near a slot machine until Monday....lol
