873 payout question

[SilverFerret]

I recently purchased a model 873 (the bars and 7's model) which pays correctly except for when it hits the bars with the 5's in them. According to the glass payout schedule it says it will pay 100 coins but pays 124. Any bars pays correctly at 20 and the 7's aside from the top jackpot pays correctly at 200. Also, I'm not sure if this is supposed to happen but I hit the top jackpot which is supposed to pay $100 and the only thing that happened was that the bell rang and I had to flip the coin switch to stop it. The hopper did nothing when the top jackpot was hit.
I have an 809 that used to pay +1 on every payout and a simple adjustment of the zero stop corrected this issue. With the 873, it only pays incorrectly on the three 5 bars and pays the same incorrect payout each time.
Any ideas?
Thanks, Jim

check wiper on hopper see if the wipe is bent back alittle , dose it pay 21 for 20 42 for 40 ect?

[SilverFerret]

Pays correctly on other payouts. I'll check.
Thanks, Jim

From what I can see, everything looks clean and intact... though I'm still learning and really have no expertise.
I find it odd that it's just one of the payouts that is incorrect. After reading a previous post I understand that the top prize does not pay anything and must be strictly attendant paid.
Thanks for the help, Jim

If I remember right there is a separate adjustment for the 100 and 200 coin payouts. On the back of the hopper is a chrome retainer that mounts over the spiral cam.. On the top and bottom are a set of contacts, they should be connected by a wire. There are two screws holding them in place. You need to loosen the screws and slide the contacts to adjust your payout for the 100 coin.. The wiper board will be marked 100 and 200, just adjust the contacts on the 100 side. Its not coming off the wiper board contacts soon enough. This is a very touche adjustment, so a little at a time..

Thanks Amachanic,
I did what you suggested and was able to get it from 124 coins to 120 coins. So here's what I'm thinking... bare with me... attached is a picture that shows the jackpot which should pay 100 coins and any bars pays 20... the glass says all jackpots, does this count as both wins on one line?
Thanks for entertaining this, Jim

[Amachanic]

It is possible that your machine pays out on combined jackpots? I have had fruit machines that paid that way. Does is say on the glass it pays for winning combinations? If not you still might have to adjust the 100 payout contacts 

[SilverFerret]

It only says what is in the picture. Maybe the glass has been changed along the way... not sure. Can we determine what payouts are supposed to be from the serial number?
I have no more room for adjustment unless I bend the contactors.
Thanks, Jim

Barry Fox at Foxs Slots might have that information. I think I had to bend the contacts on my Money Honey to fine tune the 100 or 200 coin payout.

[slotsteve]

you can see in the pic your top set is bent where the white wire goes with that bend in it  it goes farther to pay out the hundred which gives the over  pay

[Amachanic]

Now that I go back and look at the pictures again I do see that the top contact looks deformed. Look at the bottom one, thats what they should look like. You might want to remove the two screws holding it in place, then remove the contact to repair the damage.

[slotsteve]

thats what i was telling him  top one has a hump in it making it shorter  so hopper will run longer  =  over pay

[SilverFerret]

Yeah, I can see what you're saying. I'll correct that when I get home and see what I get.
Thanks, Jim

[SilverFerret]

Okay, I adjusted the contacts to where it should have shortened the payout as it is my understanding that when the contact runs off the metal strip it is supposed to stop the hopper and thus the coins from coming out. As you can see from the pictures below, the contacts continue off the metal strip yet still dispenses 120 coins. I purposely adjusted it the other way and it did give me more than 120, but no matter where I adjust it past the strip it still spits out 120.
Scratching my head, Jim

try putting a piece of tape over the end of hundred pay strip and see if it stops sooner , if you click the coin counter on hopper by hand  how many clicks it take toi stop after it,s off  the 100 pay foil? , its a em it has to be there right in front of you , also  those games only pay the highest hit so it can,t be paying for 2 hits

[SilverFerret]

Well I guess I'm on the right track as I learn the operation of these machines. I see that when this contact runs off the foil strip it SHOULD have stopped the hopper from paying out. I'm not yet familiar with how to manually click the coin counter by hand. I've heard that said before and read to do that but hesitant as I'm not exactly sure what to turn or how to do this.
Could you point out what I need to turn related to the pictures I have posted? Is what I'd be looking to see is 100 clicks before it no longer makes contact with the foil strip? That would be helpful.
Thanks, Jim

look at your first picture the arm at the top with a spring on it sitting vertically push down will rotate arm 1 step at a time
100 clicks should be 360 degrees 1 full rotation of the arm

[SilverFerret]

Sounds good. I'll check it out. Thanks

[SilverFerret]

Well I ran it up 100 steps and adjusted the contacts a 1/16 inch off of the foil strip (at 100 steps) and tested it and (as seen below) it ran way past a 1/16 inch and payed me out 120 coins once again. I see what should happen in theory and it's just not shaking out.
Still schatching my head. Any more thoughts? Thanks, Jim

[Amachanic]

I would look at the wiper contacts on the back of the spiral cam. Make sure they are in good condition and not worn flat causing them to make contact with more then one trace.  See if there is a trace ending right where they stop. Maybe you have a grounded wire to another contact.

just a shot in the dark but as the wiper runs off the 100 strip
is the bottom wiper just coming off the 20 strip
 perhaps you were right earlier and it does pay 120 coins
as i say just a shot in the dark

older ems , like his 873 jpo  only pay higest hit so it should only pay the 100 , I don,t like the look of the solder on your payout board someone has done some soldering there might have 2  wire touching  , you said your 200 don,t pay  only ring  bell  right?   your 20 hit pays right? if it was paying only a few over  i would say your over  ride is staying in too long   but not 20 coins, you can also try putting tape under the 100 pay wiper to see if it still pays if it dose there is a wire wrong  so place we sold 100,s of these 873 jpo in the 80,s never had that trouble

[SilverFerret]

It pays correctly at 200 coins. Only the max jack pot just rings the bell which after reading a previous post I understand to be accurate. 20 coins pays accurately. At 100 steps (360 degrees) the wipers are at the beginning of to 20 pay strip which means that at 200 steps (720 degrees) the wipers are also at the beginning of the 20 pay strip yet it pays 200 accurately.
Which solder are you seeing that looks incorrect? I'll take a look at it when I get home.
Thanks, Jim

the feed   f   the 50 and the 100  check those

[SilverFerret]

After discussing this with an electrician friend, his opinion and now mine is that one of the contacts to the 20 coin pay foil strip is staying closed and therefor after the wipers go 360 degrees and land on the 20 foil strip which is hot when it shouldn't be, the hopper continues spitting coins until it breaks contact of that 20 coin strip.
Does this hold water? I haven't had a chance to check out the contacts and trace the wiring as of yet.
Thanks, Jim
