Bally EM 1090 all pays accurate except 3 BARS pays nothing.

That is one big mess. Wires going every where.. My best guess is that it came off one if the top three to the right on the pic. The way the wires sitting, it looks like it was on the top, third from the right.. I wouldn't count out the top right empty connection just because it has solder on it and no wire?

Amen to that  brother! Dang bird nest with pretty shabby soldered connections... I am alittle shocked it works as well as it does...
I will keep at it..and keep u in the loop. 
Thanks

Wire appears to be red orange. Trace it back a few inches and check the color. Could be the red yellow wire used for cherries on some machines on the first solder post, in some cases have no jumper below.
Set up the Cherries and meter across the boards to see what you get. If it's open, jumper connect the wire in question and test again.

Looks like someone put their own spin on the wiring!

[Amechanic]

At this point I would trust wires colors. It looks like its possible been converted?

[DavidLee]

Would like to see the wiring on the other two wiper boards. Post photos if possible.
Thank you

[Amechanic]

    That's a good idea.. Since this machine pays R-L & L-R then you would think the outer two wiper boards might be wired the same.

David:


Not to get off track, but I will, I LOVE that CASINO sign over your games.  Does it change colors?  Where did you get it?  How much?  The Buy S Pay slot machine is great also. 


Now back on track...  I will look through the schematics that I have to see if I have a game specific one that will help.  Like it was stated before if a lot of custom work was done diagrams may not be helpful 100 percent but its worth a shot.

Haven't seen a 1090 in a long time. since it's a 3 coin multiplier does it have a relay for the 100 bar payout?  the reason I ask, I looked to see if I had any schematics, couldn't find any for the 1090, did have one for the 809, which is a 5 coin multiplier,  it shows the payout for the 100 pad on the payout disc (81) wire going to the coin count up disc and then onto a set of relay contacts that had three sets of contacts associated with it, all three are for bar payouts. so the 90 wire makes it through the wiper feelers out of the wiper as a 46 wire to the relay contact through the relay, over to the coin count up disc, through it and over to the 100 pad on the coin payout disc.  Could the 1090 have similar circuits as the 809?

I just found a min. to post these other 2 wiper boards. Still have not found the sweet spot.

That is a good question Jim..I don't know the answer to that. I will try and find out if there is a relay for the 100 BAR payout.

[Longoverdue]

This is where the other end of that loose wire (Red/w Orange Tracer) ends up leaving the Reel assembly.

[DavidLee]

I'll check out the location to and from that pin you pointed out first chance I get on the 1090.
Also might want to get a bright light and head gear magnifiers out and chech all solder joints on the wiper boards  See photo attached.
The basic problem was no pay on 3 bars, I've kind of lost track along the way.
If so everything else pays correctly?

[Longoverdue]

Thanks DavidLee,
 Yes it is just the 3 BAR payout ..all others work accurately.
Thanks again for you insight.

I need for someone to teach me how to make those jazzy circles and arrows when pictures are posted. 


As far as the no pay bars I still bet the solution can be found in one of my previous suggestions.  Additionally, on my 873 games there is a stack of switches on the back of the reel bundle labeled bars.  Not sure if its the same on a 1090.

Traced the beau plug pin in question both ways. The red/yellow 13 wire runs across all cherry contacts on the reel wipers and terminates at the
payout step up unit. On the 1090 in my shop, this wire is located on the far right second solder joint down on all 3 wiper boards. Circled the 90 wire gray as its the common among this circuit.

Set up 3 bars meter across for continuity, from the 90 wire you should have continuity all the way to the payout step up unit 50 solder lug.
When the unit steps on to the 50, I believe there will be continuity to the (F) lug feed. If this is correct 3 bars should pay.
Personally, if the wipers meter OK, I would test from the last bar out to the beau plug, Beau Plug male to female connection. Then beau plug to step up and 50 payout to the feed. Paying close attention to the 50 payout contacts.

Pretty sure this is an accurate account, but always open for corrections and insight.

Also including photo of Beau Plug Pliers and test probe / plug insert. The probe is an exaggerated for testing. I only put a slight bit of distortion on a actual pin.
