Two used machines, 1995 triple diamonds, red white and blue- power but no worky

[elweedz]

Hello all,


Just purchased  off craigslist with known issue.   Lady said they need to be reset but it didnt sound like she really knew what or how to do so.  Both do the same thing.  The light on top flashes non-stop.  The coin just passed thru when you insert it.  The triple diamond, when i pull the lever, it moves then makes a "knock" sound when it reaches the bottom.    The reels dont spin.  There dont appear to be any error codes.   I can make some numbers appear under the credits but they dont do anything.   Would greatly appreciate any help you can give.   She had 3 other machines that all do the same thing.   Seems like there is some common error on all 5 machines.

First thing I'd do is turn the machine off, pull the processor board out (it's in the lower cabinet behind the coin hopper) and check the cmos batteries. If they are dead, replace them and go from there. Some resetting will be required and info on that can be found in the IGT s+ topic forum here on NLG

Cowboy,


Thanks for the quick reply.   While I am an engineer, I know startling little of computers/electronics.  Am I in danger of really screwing this thing up or is your suggestion a fairly easy one?  I have habit of making things worse when i try to fix them.   Are there any "make sure you dont do this" things i need to know about your suggestion?

The biggest thing is to make sure the machine is powered off whenever removing or installing plugs or boards on these machines. Second is to make sure you pull straight up on the board when removing it and push straight down when installing it. Once the board is out, use a multimeter to check the voltage on the battery. If I remember right it is 1/2AA and 3.6v. Low voltage = bad battery

Welcome to NLG, make sure you have the polarity correct when installing the new battery.

And while you have the mpu board out of the machine give it a good inspection. Look at the old battery to see if there is any corrosion around it. And check both sides of the board for anything like water damage, mouse droppings, etc. If you see anything you want to double-check just take a photo of it and attach the photo to a message.  (click on the "Attachments" link below any message you are posting).

Keep the boards off of any static friendly surfaces too.

All - again thanks for the usefull tips.   So far I have identified the only thing that i can see as  battery.  It says LS 14250 on it.  I ordered two off amazon so it will be a week before i can update my progress.  Looks like they need to be soldered to the board.    Here is where I start making small problems a big one.   

[cowboygames]

That's the battery, one per board. What voltage reading did you get off them? Secondly, if you have a Batteries+ store near you  then they likely have the battery and can change it for you

[elweedz]

They both read less than .25 volts.   Just reliazed i do have those stores but amazon said they already shipped.  These machines are both circa 95 so maybe these are the originals?  i dont know.

[elweedz]

btw- called the battery place.  They dont sell the "tabbed" version of the battery which you need to weld to the mother board.  They would have to order them. 

[shortrackskater]

If you've already ordered 1\2 AA "untabbed" batteries, you can get holders that solder in easily. They're all over eBay. Just pick one that's not in China or you might have to wait a long time!

Here's a video of how to change out a battery on a mpu board. This will help.

Hi ALL,


So i got the new cmos batteries installed and confirmed voltage at the solder points.  I put it all back together and both machines still just let the coin pass directly thru the coin slot.  I checked the coin comparitors and it they both have a coin that is the same as the token that i am using.  Ideas???


Side note - triple diamonds still have big siren light flashing.

[therockinelvis]

OK you changed the batteries. Then you got 61? Then you turned key for 61-1? Then you closed the door and turned key? Did the reels then spin right to left and stop? Is the coins played flashing? Are the reels stiff when powered on? A picture of machine turned on and what you think is ready to play would be great. Also a picture of you coin comparator. The more we see the more we can help.

Have you checked the fuses in the lower part of machine? Make sure they are all good. The power switch inside the machine is ON, right? When you first turn the machine on do the reels spin for their initialization? And do the other lights on the machine come on, like the main fluorescent lights, button lights?

[elweedz]

didnt check fuses.  Didnt know they exist.  Can you help me out with there specific location?


Power switch-check
When i first power triple diamonds, it does spin.  Red white and blue does not.


Triple diamonds top siren is on, the flourescent wheel lights are on the top part of the machine lights are on.  The LED lights that indicate credits and such are working.  Button lights are not on.

I don't have a photo of S+ machine fuses handy but found the photo that is attached below. So keep in mind yours probably looks different than this example photo below.

When fixing a machine you've never had before you will need to check all the basics and power is one of them. The 115vac comes in from your wall outlet and inside the machine it is used to power a few things like the 115v fluorescent lights. The 115v also goes to a power supply that makes the lower voltages needed by the machine such as button lights, coin comparator, reel motors to spin the wheels, etc. The power supply is protected from electrical shorts by fuses, so if any of those fuses are blown it will cause certain parts of the machine to not have power. 

The fuses are generally in the lower part of the machine cabinet. They have round caps on the top, usually black but sometimes are white. You twist the cap and remove it, the fuse is inside. Sometimes the fuses are mounted near the power ON/OFF switch. There should be a label near each fuse saying what size the fuse should be. The fuse will be a clear glass tube with a narrow filament inside. The best way to check the fuse is with a meter, but often you can tell when looking at one that it is blown.

If you can post a few photos of the inside of your machine it would help us to know what you have exactly and we can more easily help. Take a photo showing the inside of the main door, the lower area where the hopper is and the entire machine with the door wide open. Thanks!

Here's another photo, I think this is from an S+, it shows the 3 fuses mounted on a metal box in lower part of machine. Be sure to have the machine unplugged when checking fuses. Even if the machine's internal power switch is OFF there is still electrical power in some pats of the machine that is coming in from the line cord. (if power cord is plugged into a power strip you can safely remove power with the power strip switch)

Roks first pic is an S slot the second is an early S+ and here is a later S+. It's under the bill stacker.
