David,
It looks like your odds step up solenoid/coil is not fully engaging. If it pulls in fully, it should step up the odds gear one step. It looks like it is trying to do that in your video.
Physically check the step up and reset solenoids on your top unit by hand to be sure they do work right.
I am looking at an 809 schematic, and what happens on 2nd coin in is that the odds relay engages (that is a relay with a brown with red wire-61). It is supposed to allow time for the odds solenoid (the one that steps up your disk red with black wire -18) to fully engage. After the odds solenoid fully steps up, it physically opens a thing called the EOS switch. That stands for End of Stroke. If you watch the action as you physically push in the step up solenoid, you will see that the linkage opens up a switch at the edge of the odds unit disk, that has a blue with orange wire --27) The other side of this EOS switch is that 61 wire -- brown/red that runs the first coil, the step up relay coil.
I hope you follow that ok.
IF your EOS opens too soon, then the odds disc may not fully step up, and the machine steals a coin.
Of course, if it does not open at all, you can put in the 2nd coin, and it will step up all the way to 5th coin in and keep stepping, and will make quite a racket.
Try this fix of adjusting your EOS switch, and let us know if that fixes it. Make it so that it opens, but opens very late in the stroke.
If that doesn't fix it, then we'll figure out something else....
Make sure you download the Bally manual so that we are on the same page.
Send pictures of your top unit and odds disc assembly....

Let me recommend that all you e/m mechanics try this to see how the EOS works.
First,put a piece of matchbook in between the EOS contacts and play the game.
Next, remove matchbook, and clip the two leafs of the EOS together with a small alligator clip.
Then play the game.
What do you see happening?
Curious minds want to know.

I noticed in the video that there was also a problem resetting the feature unit back to the first column. It took several coins in one instance. I am wondering if there are any problems with the coin switch being intermittent.

hey

thank you so much for your help.

@rdaniel: the coinswitch is new. i though it too that the coin switch is the problem

but isnt...

its very hard for me to understand it :-((((
tonight i will record a new video of the upper unit. perhaps you can see more about the solenoid or the coils ok ?

david

hey

so i could record a small video of the upper unit.
you can see that the bally try to junp to the second coin...
there is a contactplate with a few metalarms, that rotate after i put the coin in...

ive got no idea what i can do !!

This is the EOS switch (circled in black) (click the pic) that has been mentioned. Dont let it open up until the very end of the stroke. If it opens early.... you wont get the full length of actuation to the coil that advances the disk for the coin in.

thank you !!!
i have bend the eos switch a little bit so he will now open later.
but it doesnt fix the problem :-(

<a href="http://youtu.be/I-0zqIy2Hg0" target="_blank" class="aeva_link bbc_link new_win">http://youtu.be/I-0zqIy2Hg0</a>

sometimes he accept the 2nd coin, sometimes not...

:-( do you have an other idea what i can do?

oh damn it !!!!!! :-(

The Fatman · « **Reply #9 on:** May 08, 2014, 12:35:59 PM »

One thing I have done is to file the switches on the clock side of the mech . I had one switch that was pitted and not making good contact. it looked like it was but it had carbon and didnt make a good contact. The other issue i have had with my 809 is the Beau plug didnt make good contact (hopper plug). Do you have an extension cable to check the units outside of the cabinet? This is a great thing to have if your going to have a few machines. Time consuming to make but well worth the effort to make them.

Dave

hi dave

no ive got no cable to use this outside the cabinet :-(

do you mean these switches??
should i clean the contacts??

david_germany · « **Reply #11 on:** May 08, 2014, 12:54:27 PM »

ok i have clean these contacts too.
the problem is not fixed :-(((

I'm thinking that the problem could be with the one coil that counts and advances the stepper.. Looks to have been replaced, but did the install the correct replacement? It acts to be weak or slow? I wonder if it's the same coil as my stepper in my 831?

The Fatman · « **Reply #13 on:** May 08, 2014, 05:00:38 PM »

Could be the stepper coil ... good eye .. looks kinda shotty and cant tell the value of it. Might be too heavy of a gauge wire.
The switches i was talking about are the ones located on the side of the reel mech behind the fan or clock. If you need me to send a pic i will if you cant locate it. If need be I can ohnm the proper coil and you can check yours to see if it is the right one. If the wire size is too thick ... it will have too much resistance and might not pull in well enough to advance the disk. Also check the operation of the stepper by hand to see if it advances correctly. Might have a worn gear or stepper arm.

The stepper seemed to work fine in the video when it was done by hand.. If you look close at the wires you can see where the soldering iron melted the outer plastic covers on two wires. That coils not original. It wouldn't hurt to clean and check the coin switch contacts, also the contacts on the handle release. I had something similar happen on an 831, and cleaning and adjusting those two switch stacks helped. On this machine I'm leaning towards the step up coil.

I lost a post but that's ok.
You can remove the 4 screws that hold the light board onto your top unit. Then you can look inside while the machine is running. You can also pulse the coils with it on this way. You can learn to use a jumper to test stuff, too.
However, please look at the handle switches as the problem. It sounds like the handle assembly switches with colors of blue/yellow(23), and blue/red(21) are not opening after you insert the 1st coin in and the handle paddle drops (is released). Pull out the reel assembly, and look in at them. I bet they are almost touching. carefully bend the shorter blade away just a little bit.
Post a photo, and turn off machine when you leave, you might have a coil sticking on and it will burn out you don't want that.
If you want to understand how the machine works better, read oldreno's trouble shooting post. I think it's in here somewhere. And download the bally manual for better reference of parts.
Nice Pix!!!

The Fatman · « **Reply #16 on:** May 08, 2014, 08:24:24 PM »

Chances are that the handle relay doesnt drop with the first coin. That is what mine does most of the time and it wont advance the odds relay if it doesnt drop and close the switches.

soo

i think the problem is fixed
soon.
now it works but sometimes, i mean sometimes only the machine steals the 2nd coin.
i have cleaned all contacts of the upper amd reel unit.
only the handle release solenoid isnt cleaned.

perhaps i should cleaning the contacts again and more?

sorry for my english !!!!

david_germany · « **Reply #18 on:** May 09, 2014, 10:53:04 AM »

oh no :-(
the problem is coming back...
damn it !!!

but i think i should cleaning more the contacts.
ill try this and write you

Amechanic · « **Reply #19 on:** May 09, 2014, 11:40:22 AM »

I would go over the coin switch contacts on the side of the reels. The set of contacts with the coil to engage them, and I would make sure to clean and check the contacts on the handle release.
