Picked up an S+ that had some issues (so I replaced the door optics & battery). After a clear the game plays fine. HOWEVER, when I continue on to enable the bill validator everything appears fine until the final reel initialization -- enabled the validator changed 9-0 to 9-1. Reinstalled the game chip, turned on, closed the door and code 61 changed to 61-1, etc.. During the final initialization when the reels started to spin they froze and I got code 43. Swapped around reels but the code remains on 43. THEN, I replaced the CPU board and the same thing happened. Game plays fine (all reels spin fine) until I enable the bill validator and go to final reel spin. The reels are not rubbing on anything. They work fine as long as I don't try to enable the bill validator. Also, during machine power on the BV cycles. I am ruling out the CPU as this happens with two different boards. Any clue as to what is wrong?

You said you swapped the reels and still got the [43] code....the problem is in the harness.

Leave the reels as they are....SWAP the 2nd and 3rd Molex connectors and see if you get a code [42] to verify.

I swąpped the 2nd and 3rd Molex connectors and still have error 43.

Until I try to enable the bill validator, the reels and game works fine. No codes and all reels spin. No errors. Are you suggestion there is a problem with the harness/connection to the BV?

Again, if I do a clear, but do not enable the BV, everything works fine. It is only after I do the BV enable that the game locks up and get error 43.

Did you also set the denom with set chip?

JethroP · « **Reply #4 on:** February 21, 2022, 10:09:21 PM »

yes, to 25 cents. All the settings with the key chip went fine. After I reinstalled the game chip and did the reset, that's when the error 43 came up.

Which SS and SP chip is on machine and which set chip did you use?

JethroP · « **Reply #6 on:** February 22, 2022, 10:02:53 AM »

The chips are 1271 and 3353. I can't tell you which clear and key chips they are. I've had them for a few years, never had an issue with them, but there aren't any numbers on them.

You can always pull the head and see if the problem goes away. I think this is coincidental but as my wife reminds me frequently - I have been wrong before.

None of the following has to do anything with the bill validator... but it might have to do something with power draw aggravated by the presence of the validator ?? (long shot).

On the top corner of the MPU board there is a set of 5 resistors - each one is for the reels.
The S+ was created with the ability to support 5 reels but in North America you never see more than 3 reels.
You will see that 3 appear scorched while the other 2 are pristine.
Typically when the code does not change by moving the reels around and it won't clear it usually points to a weak resistor.
You can try moving one of the unused ones to #3 and see if it resolves the issue.

There are also reel drivers on the MPU that you could try swapping around as well.
I don't remember which chips they are off the top of my head but its documented in other threads.

Here is the thread with the reel driver chips.... U1, U2, U3 might be easier to move these around than unsoldering resistors (at least as a first step).

So, we have to rule out the reel harness and the board. double check the connections to the mother board, especially where the bv plug connects to the motherboard J-6

if it is in the right place, try and disconnect it and see if that makes a difference, that is the only plug that interfaces with the bill accepter via the power supply for the bill unit.

what type bill unit is in the machine?

Have tried two different boards (one is 16mhz, the other is 10mhz). Neither has burnt resistors. Both boards cause the same error code 43.

The BV is WBA-10-SS. I pulled it out and the error 43 does not clear.
I removed the connector at J6 on the motherboard and the error still does not clear.

41,42,43's can be a challenge to clear but this sounds like it is being unduly persistent.

The official way is to open and close the door.
Try pressing the white button multiple times to cycle through all the option menus then close the door.
If that doesn't work you may need a ram clear.

Typically you would have a clean ready to play machine and the 43 pops up as soon as the reel goes to spin.
When changing boards you should NOT maintain a 43 - this sounds like a glitch on the CMOS and a RAM clear may straighten this out.

OMG. Now the problem is changing. I opened and closed the door to try to reset the 43 error (like I had tried many times before) and it changed from error 43 to error 42. After a few more times, it cleared and I was able to play a few coins. Got three 7's but didn't record any winnings. Also, the BV won't accept any bills. Finally, played a few more coins then all three reels went into a slow continuous roll.

Sounds like it was the first time your door optics "saw" each other.

That's why you got the [42] to pop up on the display from the swapped Molex connectors I asked you to switch earlier.

The fix is to adjust your door optics correctly.

They are making the reel errors happen because the receiver optic is missing the emitter beam as the reels are turning.

jay · « **Reply #14 on:** February 22, 2022, 05:04:22 PM »

The slow continuous roll is the standard behavior of a 41,42,43 error.
Triple check with the power off that the reels spin smoothly and that the reel strips are not touching anything.
On mine there was a wire going to the candle that was just close enough to the middle reel and when they spun i suspect the spinning drew it inwards.
It really takes nothing more than a passing cats whisker to cause a reel tilt - they are ultra sensitive. Security thing.

Did you run a clear ? if so a SET will be necessary to re-enable the bill validator.
Also if your flipping between a 10mhz board with a 1271 and a 16mhz board with a 1272 game chip this may also require a SET.

Is the validator lit - that is a good indication if its ready to accept bills.

Per not paying out on a 777 did it go to a hand pay ?? the hopper limit is likely a 300 - 400 coin limit and a 777 would likely be big.
Typically the machine clicks, the candle blinks, and the floor manager appears with a giant cheque...... you reset using the key on the side...
The common theme here - regardless if the cheque shows up or not - is that no coins are expelled on a hand pay.

The other possibility is that the reel strips are in the wrong spot. They have little knotches on the side that line up to a nub on the reel baskets.
The reel baskets also might be for a slant top (little embossed ST) on the reel basket.
Slant tops have their reel glass at a different angle so nubs are in a different spot. Subsequently if someone put a ST basket in an upright (to call the machine parts complete) the reel strips would need to be put on offset from the nub to make the correct symbol show in the upright reel glass.

In the home market no one really likes the slant tops due to the size/weight - Its one thing for a buddy to lend a truck its another to get him to help you carry that to your basement.
Thus many slant models are parted out and ST baskets sometimes land in upright machines.

Thanks for all the suggestions. I'll look into them tonight. In the meantime, you raise an interesting point, and something I've read in other posts....should I be using the 10mhz or the 16mhz board given the SS and SP chips I have? Also, are the CMOS and the other large chip on the board interchangeable on either board? BTW, the game is Sizzling 7's (if that makes a difference), 2 coin play.

sixcardmark · « **Reply #16 on:** February 22, 2022, 05:37:45 PM »

Use 10mhz board with SP1271.

JethroP · « **Reply #17 on:** February 22, 2022, 06:16:17 PM »

Progress but I'm not out of the woods yet! I found that the baskets are slightly out of round, and looking through the glass noticed that #2 and #3 baskets very sightly tough the front display during a point in their rotation. I can't push the baskets back any further, but trimmed the plastic display slightly and eliminated the rub. So the error messages are gone.

Now to get the BV working. Did the key set but the BV bezel is not lit. The BV cycles on start up but doesn't accept bills. Thinking I should try swapping out the BV, but I don't have another one. Ideas?

JethroP · « **Reply #18 on:** February 22, 2022, 08:04:49 PM »

I'm almost there! Found another BV on my shelf and swapped it out for the one in the machine. It works! It seemed like it wasn't working for a few minutes then all of a sudden I noticed the bezel light on. Hmmm. Well, it'w working now. I want to change one thing, hope someone can guide me: When I feed it paper money it changes it to coins out of the hopper immediately. I'd like bills in to go to credits, but winnings to be paid in coin. What settings do I need to change to do this?

Push the cash-credit button to lite it up before you insert bills.
