Easy way to tell if itâ€™s a .25c coin guide is by the two raise ridges running down through the middle. The .50c and $1.00 donâ€™t have those.

I tried Jim's Optic test : http://newlifegames.com/nlg/index.php?topic=14723.0

The popsicle test worked on 11_1 and 12_1, but NOT on 10_1 . I did the test twice to make sure the results were accurate.

Time for new optics or remove q2-q4

Reassembly and give it a try.

I did take it apart and clean it before the test. Question Sixcard, why are there two options here? When you say Q2-Q4, it looks like just a little tiny chip with three soldered-on points, sound about right? Also, does that just turn off the sensors? Do I lose some sort of abilities if I do that?

When you do this mod to the coin optic board it allows you the option of now using the coin comparitor or using a coin mech, the older mechanical type. The bad is that now the comparitor will allow extra coins to be inserted, but once you hit your machines limit, 2 coins, 3 coins etc., the extras will just go into the hopper and no credit will be added. The other thing about this mod is that your game now will accept both quarters and tokens because it canâ€™t tell the difference.

I have done this modification to several hundred S+ machines, it still will stop additional coins from being accepted, as far as the normal machine functions, you can never tell that you did anything to the optics, EVERYTHING OPERATES AS IT SHOULD!! . the inhibit feature that will not allow additional coins to be accepted is a function of the program and a wire that is connected to the CC-16, which will remove power from the CC-16 when the max amount of coins has been inserted. on a machine that has the belly door, remove the cc-16 and bracket , now plug it back in and hold it in your hand, close the door , and watch what happens as you insert coins, you will see the CC-16 LED go out when you hit the max coins inserted.

Thanks for clearing that up Jim! I had one machine accepting extra coins then returning them to tray after the spin and thought it was one I had done the mod to, but it was the comparitor in that machine that was causing it. The rake arm was bent out so it could not reject coins.

Over the years IGT made different versions of the coin optics board. They are similar but the transistor that gets removed by the mod is called Q2 on some boards and Q4 on other boards. It is always a 3 legged part. On some boards there is also a round optic part that is called Q4, you never remove it.

Wow, great info guys! I removed the Q2 chip and am still getting the code 21 error, and am still unable to clear it, how do I proceed from here?

sgolembiewski0903 · « **Reply #31 on:** October 01, 2018, 03:37:17 PM »

I saw someone mention that they cleared this way, worth a try?:

I was able to clear my error by removing the motherboard several times and reseating it, along with coin hopper, DBV, coin comparator and cleaning all optics with a q-tip and compressed air. My wheels quit spinning and the machine returned to normal and started dropping coins (finishing out it's previous payout) Apparently the coin in error occurred during a pay out thereby killing the DBV and coin accept ability. As usual, I don't know what the exact fix was but all is back to normal.

The code 21 should disappear for a few seconds after you latch the door. If it does not you may still be in open door mode.

It doesn't make sense that your displays stay lit when you close the door. They always go blank then come back on. Simply lifting the latch should make the displays go blank except the coins played. Putting the latch back down should take a couple seconds to light the displays again. With the door open pushing the test button will light them again. You have pushed so many buttons and turned the key. Try pushing the tiny white button next to the on/off switch several times until you reach the end of the pages when the displays should go out then came back on. Is it possible your door optics are not seeing the door as closed and thus since there was a coin past the optics set off the 21 error. I am leaning heavy on door optics since it will not clear and the display doesn't go blank. The 61 after the battery change has me stumped although you didn't get 61-1, you got 63-2 or something. Should have been 61 then 61-1 then close the door turn key. It didn't sound like you got that.

Elvis, imI getting code 21 just to clarify. It's not going blank when I open and close, is there a test for door optics?

So probably like Elvis said, dolr optics may be the issue?

therockinelvis · « **Reply #36 on:** October 01, 2018, 06:05:45 PM »

An easy way to check. place a piece of painters tape on the cabinet where the optic is. Then put one on the door where the optic is. then draw a line where the optics are. Then close the door and push the latch down. Do the marks line up? If not align them. S+ door sag quite often. Next check the tiny wires that go into the eye's. They break easily. They are both different sender and receiver. You can take a picture with your phone to see if the emitter is flashing.

get into the input test menu, go to test 13, now close the door and latch down, the number 1 should be toggling back and forth from a 1 to a 0, if not then something in the optic circuit is not working.

Jim

And the mystery continues... As I lift the latch up and down it does toggle from 13_0 to 13_1.

The optics don't look PERFECTly lined up but they are close.

If I cycle through all of the test options, the screen will go blank for 1-2 seconds before it displays the "21" again
