I've got an early S+ (10 Meg MPU on the lefthand side) that just dings when power is applied. The Reels aren't stiff and nothing is on the Display.
So what I'd like to know is do the early ones suffer from the same Molex Connector problem that the later ones do? Same MPU and Motherboard, so I'm guessing that it's also susceptible to the same 'burnt pin' issues as the newr ones.
Now, the problem I see is that the Harness is much different than the newer models. I'm not even sure where it terminates on the other end.
But, I did try the wiggle trick to see if the Reels would energize, but had no luck.
Not sure what the constant dinging is that I hear, unless it's stuck in a hand pay and can't be cleared until it boots.
Here is a link to a video of a machine doing the same thing as mine, but his dings are different. But I'm assuming it's the same problem.

Let me know your thoughts.

Can you swap out the SP chip?
What are the SS and SP chip numbers?
Also, is the denomination lamp on?
The other lamps for the Winner Paid, Credits, Insert Coin, Coin Accepted, and Coins Played windows should be off.
If your SP chip is, or may have been inserted in it's [GAME] socket backwards, and the machine powered up before you got the machine...effectively cooking the guts of it.
That SP chip may have been zapped....try another known-good SP chip.
The fluorescent lamps should be on.
If the reels aren't energized, then I' totally be suspecting the power supply harness, but you've already wiggled that power Molex upwards - in effort to try to get a new contact on the pins inside the housing.
Check the 3 Quick-Blow fuses...esp. the top 6 amp fuse.
From top to bottom...>>>
6A
8A
6A
You're correct about that power supply harness....it is different.
Runs from the motherboard male header pins, straight to the power supply.

I'm still troubleshooting, but I'll post what I know now and answer some of Bunkers questions.
My SP is a 1045, which I couldn't find a listing for, so without knowing the type, I probably won't have anything compatible.
The machine is a Full Fruits with Bars according to the Award Glass. But the SS in this game is a 8534, which isn't listed in the Bible under that game. The only listing I found for it was on the old site, shows it as a 10CM Type 0 3 Reel.
The Denom Lamp is not lit, nor are any of the Displays. The Flourescent Lamps are all on, and the Fuses are all good.
I verified voltages at the Molex with some help from Jim, and they're good.
Next step is to put a different software set up on the original MPU and see what happens. The original Chips in a fresh MPU did nothing.
Could be bad Chips.
-
Could it be SP1048 rather? That one is more common.
Another one that is also kind of common is the SP1145
I'm just wondering if it's just a typo.
Anyways, you'll know for sure when yu get it to boot up, go into the accounting, to bring up what version SS and SP chips the MPU sees installed.
That ARMY FRUIT GAME SS8534 is Paytable ID 415A at 93.5%
You're right...it's a 10 COIN MULTIPLIER! Sooo cool! :cool_thumb_up:
It sucks that they're not working on a known-good MPU.
Makes me wonder if they're for the straight S MPU's or the even older M MPU's?
I think your chips are ok.
The military chips gives us nothing, zilch, nada nada, nada.
I have a few ARMY chips but never been able to get them to work either.
Also, I don't have a listing what CRC they're suppose to be.
I wouldn't be able to verify whether or not the checksums on them are okay or not.
Forget about PSR or PAR sheets....lol
-
IGT S and M slots only used a single EPROM (RSXXXX) for the game prom and reel prom. My IGT M slot matches that machine, but mine is 5L vs 5CM and has RS2024 chip installed.
-
Thanks for the great information thus far.
Here's a quick post with a photo of the 2 chips. Definitely Army.
Will post more when I get back on this one.

I would put in a SS3226 5CM to match the award glass.
-
Thanks for verifying the ARMY chips.
I was just looking at that award glass.
There's a couple of 14 and 18 credit awards...that's extremely unusual.
Oh..a couple more notes.
The Denomination lamp should still come on even if there's NO MPU installed.
That's running on an entirely different voltage line.
If your display isn't coming on, I'd check the fuses on the power supply.
With the MPU in, pulling out the top 6A fuse, turns off the power to the the coin comparitor, and the display, but the denomination lamp will remain on, as well as the fluorescent lighting. The reels will still be "stiff" too.
Also, the SP1045 chip.
On the label, in parentheses, it states (Standard).
That tells me that there's really nothing special about the chip.
It could be just a plain Jane Type "0" programming in it?
On another line, the checksum is written as (6AD3).
You could throw it into a chip programmer and see if the CRC matches?
If the CRC doesn't match, then you KNOW it's corrupted.

It's not a 5CM award glass. It's a 5L glass (no multiplier).

That pic is Tilts machine, look at Ash's pic.

10-4. I stand corrected.

Quick update, no progress though.
Tried good MPU with different Software, still doesn't boot. Reels still free-spin.
Reinstalled original MPU with original software, now the dinging is gone, but nothing else is working other than the Flourescent Lights. Still no Display or Reel action.
Guess the next step is a different Motherboard.
Thanks for keeping up with this.

I totally agree with changing out the mobo...It's the only thing left to swap out. :scratch-head_3:
I also told mwade the same thing....he's the fella that made that video of his Wild Cherry dingin'.
I hope you swap it out...I want to see these Topics solved! lol
-
I didn't have another motherboard to swap out but I took the one from the ding, ding machine and put it into my machine with the 3200 issue and now the 3200 error is gone and the machine is working fine, telling me that the motherboard in the ding machine is good and it wasn't the motherboard creating the dinging. I believe it is the power supply on mine and it has the type that isn't a convenient little box to replace but a open transformer type one that I never see on eBay. Curious to see what cures yours.
I appreciate all the help from everyone.

Latest update....
Found a burnt trace on the original Motherboard, so I replaced it with a good one from my stash.
At this point, the Reels now get stiff once power is applied, but that's about all it does. Still have no Display. All other lighting is good. All fuses are good.
Tried a good MPU with the original software, no change. Tried good MPU with different Software, no change. Tried original MPU with new Software, still no change.
Not sure which direction to head next. I don't have a spare Display to try, but I don't think that would prevent it from booting up. I could be wrong. Went through the 61 process blindly hoping that I could get a Reel Spin after closing the Main Door and turning the Key. Didn't happen.
I will search for an older style Display and see what happens next.

Reels energized is good.
Your fluorescents and denom lamp should be on as well.
I have a question I need your help with.
Could you show a good photo of the back of the entire door?
What in the world is that ribbon cable & circuit board on the reel shelf for? :scratch-head_3:
We need to see what that is hooked up to....an extra display panel??
-
What do the candle lights do? If they're blinking then the MPU is booting and you probably have a bad display or wiring to it.
-
I'll post a photo tomorrow.
That Ribbon Cable is connected to a Display (Older Scrolling type used on the M Slots), so there's no typical Denom Lamp and back-lit Insert Coin/Coin Accepted Windows on the Reel Glass.
Also, there's no Candle, nor is there a place for one.
This whole machine seems like a mix of several different IGT models.
I do have a photo of the 2 Display Panels.

Yeah, it's different than any other S+ slot I've ever seen. The candle sure is handy to have so if nothing else is working properly you can at least see if the MPU is booting or not. You're really working in the blind with this one.
-
Also, there's no Candle, nor is there a place for one.
Is there a candle harness running to the topbox at all?
I'm surprised that an S+ with that many displays, doesn't at the very least, have a candle?
Somebody may have taken/swapped the original topbox?
I've seen topboxes that didn't have the holes for a candle but the harness wass still available.
I ended up drilling holes to install them.
As for that ribbon candle red display, I had one of those a bunch of years ago, but threw it out as I couldn't get it to work.
It never affected the rest of the machine not having it...I just threw in a different game, glss, strips & chips.
My guess is that particular display may only work with specific SP chips.
I'll betcha if we had the SP1045 PSR for it, it would tell us how to enable/set that odd display.
I'm going to dig around for some closely numbered PSR's to read if there's any info on it.
***Update***
While I really didn't see anything relating to your display in PSR SP1044 or PSR SP1047, I'm suspecting that it was a display made to show game events/messages such as [Insert Coins], [Coin Accepted], etc, etc.
Maybe soon after, they saved some money by just changing the reel glass and using lamps and bulbs?
-
This thing just keeps getting more and more weird.
Taking Mark's suggestion, I decided to check out the Top Box (haven't removed the Award Glass at this point yet) to check for a Candle Harness and was surprised to find some sort of ancient Progressive System up there.
Guess I'll carefully remove all of that stuff and see if I can spot any signs of a Candle Harness in there somewhere.
See photo of this crazy looking contraption. First time for me anyway, some of you more experienced Techs may recognize it.
I'll also look into seeing if I can't somehow install a more standard S+ Reel Glass Display with the Insert Coin, Denom and Coin Accepted Lights along with the Reel Glass to match.
Stay tuned for more updates.

That might be a Mikon display,
Follow the ribbon cable from the display to the controller.
See if it says CHAMI, CHAMII, LED5 on it.
A ChamII+ is a standalone progressive controller.
A ChamII (non plus) requires a CON2i SuperController to drive it and is part of a linked controller system.
A LED5 is a Link Extension Device that gets plugged into a CON1 linked controller - sometimes you will find both in there.
A ChamI is the standalone version of the LED5 - these are super rare.
I have never seen any of what is in that top box - it looks like a massive power supply.
-
Holy smokes...I've only seen that huge blue capacitor once before....that thing can zap you like a police stun baton!
That vertical board I believe is a CHAM 1 or CHAM2 progressive unit with the ribbon cable running up and plugging into the back of the display.
I think I have one collecting dust on a shelf...lol
It may be the earliest versions of what a progressive game IGT had back then that was called "Megabucks"? :scratch-head_3:
