Bally EM 1088? not paying out on 2 winning conbination only..

[Amechanic]

I just got this machine in, and it's seems to work fine except that it's not paying out the Bell, Bell, Bar combination, and the Bar, Bar, Bar combination?.. This is a single line 3 coin Bally EM, I think its a 1088? I found that one of the wiper board contacts on the second reel was broken off.. I replaced it, but it didn't help with the no pays... My payout wiper board checks out, no broken wires, and the 18 coin payout circuit checks fine with my VOM Meter... Tomorrow I'm going to check the cabinets beau plugs for the reels assembly for a broken wire..

My question is this, are these two payout some how working in series? The only thing I can think would be the third Bar symbol on reel 3? That wiper boards contacts seem to be adjusted correct, and I don't see a broken wire on wiper board 3... Do these two jackpot payout share a common payout relay, like the Plum's do in some EM's?? I'm about 90% positive the problem is contained to the reel assembly and beau plugs..   

Hopefully OldReno (Donnerpartyof8), OpBell or someone else might have an idea... 

I just realized that I didn't check to see if the 3 Bell jackpot paid out..    This is a family owned machine they were hoping could be repaired.. It has a been in there family for 20 years..

Thanks, Gary

I Think you should check the "BAR-relay". It's sitting on the reel-unit at the right side.

Is the alignment on all 3 of your reel wipers good?
Set up the pay, and check ohms from the 90 wire on 3rd reel to the 18 pay wire (51?) coming off the 1st reel.
Actually, the best check is from the male pin 90 wire to the male pin 51 wire (or whatever it is) directly coming out of the reel mech plug itself.  That way you are assured that your reel mech is reading it completely.
I would look for broken wire in the plugs last, as unless someone has been dicking with the machine, they usually don't break on their own.
Go through all pay combinations (every kind of pay at least once) and make sure that the bell/bar pays are the only ones not working.
Also, check the new wiper cuts to make sure that they are correct with the old wiper.  You must often cut the metal yourself to separate the pay structure from the 6V portion of the boards. Did you replace the wiper, or the button on the reel board?
Does this machine pay L to R and R to L?
For giggles you might want to record the reel strips and the pays for posterity...we can calculate the % that way.
I urge all users to record strips and pays just for that reason, and that we can share info and differentiate types of machines.
ANY PICS Amechanic???
Also, one last question, does it pay Or Or Bar and Pl Pl Bar pays???

I was just heading back out into the garage as I found this.. The center wiper I replaced is correct, top 3 contacts are one group, then 3 sets of two for the rest. I learned the differance in the wipers the hard way a couple years back, that not all 9 contact wipers are the same  .. I will take my camera out with me today.. When I got this machine in for service one of the first things I noticed was that the right reel beau plug had damage. One round female connector was pushed out the back, and the female pin right next to it was shoved half way out. I fix both of those, and straightened the male pins. That's when I saw the broken wiper    I changed that and tested, but still no payouts on those two combinations. The owner gave me a rough payout problem list. A lot of 1 coin over pays, but that was an easy fix, since the payout zero stop bumper wasn't adjusted correct. I was going out to check 3 bells and orange / bar.
I still want to check the left reel beau plug just because of the damage to the right one. I will try to OHM that circuit. Thanks Donner..

Okay.. Quick up date here.. Any payout ending with the Bar symbol going left to right does not payout, but they do all payout if the jackpots are right to left are paying correct.. The 3 Bars and three 7's don't payout.. Every other paying jackpots are now correct except the third reel ending in Bar or 7.. I'm going to look a little closer at my third reels wiper. A correction, this is a 1090 EM and i attached a picture of a relay mounted on the back wall behind the reels. whats that one for? top one looks to be a buzzer.. Any more ideas would be helpful..

Okay.. This is now a fully pay 1090 EM..  I found that the top contact on the third reel was not making contact to the buttons of the wiper board. Removed the wiper and straightedge the contact, and once it was reinstalled the machine now pays on jackpot ending in Bar to the right. I will work on getting the reel strip symbol information.
One quick question for Donner.. If my second wiper is missing the second wiper from the top, and its a group of 3 connected will that wiper still work? 1-2&3 wiper contact are all one. See pic..

Hi,
I see you are missing the 2nd wiper down.  If there are NO connections wired into that row on the board, then the wiper will work fine.  However, I suspect that the 2nd row buttons are wired in, so you will miss out on some pays.
As a fix, if your soldering is good, you can cut off one of the unused fingers on your wiper assembly, and then solder it in place over the missing one.  Be sure to tin both pieces well, and you can carefully lay them together and heat them until the solder flows.  You have a goodly amount of copper between them to solder, which makes for a good bond.
I have done this and it does work, and for quite a while if you take your time at it.
Otherwise, replace the wiper with a new one...
BTW thanks for posting the reel strips.  Maybe someone will take a shot at calculating the %...?
It is nice to have them on file here I am thinking.
