I'm working on a Bally 6000.  The problem is that the BV is not communicating correctly.  I keep getting a '29' error.  Here is what I've done so far:

1. changed BV with a known working one.  It still gets the '29' error
2. tried the 'non-workng' BV in another 6000 and it works fine
3. checked and tested dip switches on main board.  performed continuity test on dip 2 switches 5 and 6 - both work fine.
4. dip switches are as follows dip1 - on,on,off,on,on,on,off,on   dip 2 - off,off,on,off,on,off,on,on   dip 3 - off,on,on,on,on,on,on,on
5. checked continuity of the harness from BV to plug for PCB in the back - all fine
6. the switch that detects cashbox door open has been checked and is fine.  It is also taped closed (simulating cash door closed)
7. I've done several clears and pulled out and pushed in the BV many times with same result - error '29'
8. dip switches on BV are all off.
9. The BV keeps cycling and then gives error '29'

Does anyone have any suggestions on what to try next before I switch the main board?   If I need to switch to another main board, do I need to switch the game chips in sockets 18 and 20 between the boards?  Does I need to switch anything else?? The differences between my two 6000 machines is that the non-working BV machine has a progressive and a single pay line.  The working BV machine does not have progressive and it has a diamond pay line.

THANKS!

Check the connection at the left rear where the bill transporter plugs in.

Thanks for the reply.  I checked the connection and it was good.  I took out reel 3 and even unscrewed the connector and plugged it in by hand and still error 29.  I believe the BV can be ruled out since both BV work in my other 6000 machine.  I checked the continuity of the cable and every wire was fine.

Try switching the cables from the BV to the backplane.

Ok - I'll try that next.

In the meantime, I thought I'd start from scratch and do another clear and record it.

Here is a video after reseating the BV:

I switched the cable from the BV to the backplane  PCB and the error '29' still occurs  :25-

So I have the cash box door switch closed permanently and the cash box in to push the two plastic tabs up through the BV optics - as I'd expect.   This produces a '29' error.  If I remove the cash box and push the tabs up by hand, I get a '27' error.  This is a bill jam error and there is definitely no jam.  Does pushing these tabs up by hand normally produce a '27' error??

Anyone have any other suggestions before an mpu switch?  Also, does anyone know if I HAVE to switch the game chips when switching the mpu just for this test?

Thanks

I don't think there is an issue with your BV. I think you may have a bad cash can and or an issue with the BV door switch. I always have a boat load of cash cans on hand so I just keep swapping them til I get one that works. Your 27 & 29 errors are not that common, especially the 29. a little baffling.

Thanks for your response.

Both of my cash cans work in my other 6000 and I used the BV cable and cash can switch of the working machine and I still cant get this thing to work.  I really don't want to start messing with my mpu that works but I don't think I have anything else to try :(

Jim

I really don't think it's an MPU issue. More often then not we miss something really dumb right in the area of the problem. Have you double checked all your dip switch settings on the MPU? If you were a little closer I'd say just bring it here and we'd figure it out. It drives me nuts when I can't fix one over the net !!

could be dirty or bad  dip switch

lindam1,

How far in NE PA are you??  I'm in lower bucks county.

I would like to be able to stop by to figure this out!

Jim

Hi Steve-

Thanks for the reply.

I pulled the mpu board out and checked the continuity of the dip switch - all seemed fine.

Thanks,

Jim

Jim,

Around Carbondale

Darn...that's 2 1/2 hrs :(

WTH is 6 hours (2.5x2 for drive home and time BSing....versus 48-72 hours on here?)

code 50-29   is  a bill  acceptor communication error.   I think your dip switch settings could be wrong.  DS2 denomination  1-4  yours is set for .25,  there is another setting for just 25, I don't know what the difference is.   DS-2  5-6  are the bill acceptor   yours is set for JCM   WBA.   DS-3  is for Market code jurisdiction,  1-4, 7-8.  I don't see any thing that matches your settings.

I would compare the two and change according and see  what happens.

 
Jim

Jim,

Thanks for the response -

I wanted the machine set to .25  I think the setting for 25 means $25 and my 1-4 switches are set to off,off,on,off, which should be .25

I have a WBA-13-SS so the DS switch settings 5 (on) and 6 (off) should be correct and I checked the dip switches to make sure the ON/OFF works.  They checked out fine.

My DS3 settings should be a code 01, which in NJ.  All DS3 switches are ON except switch 1.  I think that's set correctly.

The dip switch settings on both MPUs are the same.

sheesh, this is driving me nuts!

Jim
 

HA - that's true!  And I would certainly be able to get it fixed :)  I'm going to try to persevere through this though, hopefully with a lot of help of folks on this forum, until I see those green arrows!!

As for the settings on DS3   your post #1  has them listed on, all the rest off. 

there are only two items left, the board and the backplane itself.  the only way to eliminate is to swap them out, one at a time.


Jim

Good catch- yeah, I had the first post backward on the DS3. I fixed the post

I was afraid that I was going to have to swap out the mpu and/or backplane

Can you tell me if I have to switch the game chips on the mpu if I wanted to use it as a test only?

Thanks,
Jim

More food for thought. BV must be an 003 for Bally. 024 is for IGT.

If you try all that you were told,  try swapping out the housing for bill acceptor & cash can. Worth a try if all else failed to fix.

both dbv work in his other bally so they are 03 , I still say dip sw or harness from cash can

I switched the harness from my other machine and still got error 29. I think I'll attempt the mpu swap today and see how that goes

Speaking of the harness, the only thing connected to the BV is made in the left rear, right?  The harness goes from the backplane to the BV connector and to the cash can door switch, right??

Thanks
Jim

yes your right on  harness

OK - I switched out the MPU with a working MPU and I'm still getting the '29' error.   I'm going to quickly switch out the entire BV and cashbox assembly and use the BV and cashbox from the working machine...ugh

Jim

that's good that means  it's  not mpu , when you pull cash box  make sure wire d for door are on right lugs on micro sw

Swapped the entire BV and coinbox assembly including the BV and cashbox.   To compare apples to apples, I did a clear and then recorded the bootup again.  There are some differences now compared to the first video I posted.  During bootup, the green arrows did not light like they did last time.  The BV still does not work and gets the '29' error.  Another difference is after the '29' error, I open the door, reseat the BV and close the door - after this, the BV does not show any lights but the '29' error is not produced.   Last time '29' was produced.   The BV does not accept bills and there are no green arrows or even a red light.  I open and close the door, the BV recycles, still shows no lights, but does not have the '29' error...

new video after assembly swap is here:

I haven't gotten anywhere so I'm not sure if this is progress :)

I haven't switched out the backplane yet.  Any more ideas before I switch that out??

Thanks,
Jim

I would  check dbv plug on back plain to make sure there isn't a pin missing or bent , it happens  and the more times the plug is moved the better chance it might have happen

I double checked the pins on the backplane connection and the connector at the BV.  The backplane connector pins were all there nice and straight.  The connector at the DB is fine as I'm using the harness from the working machine.

whew...

Jim

You have probably done this but ram the cash box in and slam the door closed.

I've rammed it several times and slammed the door.  I also permanently tape the cashbox door switch closed.  I tried to push the cashbox hard enough so it would come out of the back of the machine :)  not looking good.  My last hope is switching out the backplane but I'm not feeling it.

Complete history...

When I got the BV and cash box months ago, it worked fine.  I've had the machine off for about a month or so.  A few days ago, I had noticed there was no power to the machine.  I found that one of the circuit breakers was bad.  I changed the switch assembly out and powered the machine up.  The BV worked fine but a little hinky.  Sometimes the BV would recycle and show the red light (not a '29' though).  There was no associated error.  I would then open the cashbox door, pull the cashbox out a little, slam it back in, close the door, pull the BV out a little and reseat it.  The BV would recycle and the usually work fine.  I then wanted to change the denomination of the machine from 1 dollar to 25 cents.  I changed the first 4 dip switches on DS1 from 1 dollar to 25 cents.  I did a clear and then rebooted with the same mains.  This '29' problem started then and I can't get rid of it.  I figured it was something simple but I tried everything I could think of.  I even changed the dip switches back to 1 dollar, cleared, rebooted...and here I am :(

OK - so before I make the backplane swap, I thought for kicks I'd put the entire BV/cashbox assembly and harness that was originally getting the '29' error into the machine that was working.  I put it in, booted it up and it was perfect - accepted bills no problem.  So I think that rules out anything to do with the BV, cashbox switch and harness...can it really be the backplane????  sheesh....I'm going to try to swap that out tonight.

I've been an EM pinball guy for about 15 years...After I get this working, I think I'm going to stick to pins and leave the slots to you guys !!!!

Thanks for those that are hanging in there with me.

Jim

we all get those that make us bang our heads into a wall  , few us  marry in that, you find it jim :259-

I switched the backplanes out and no change...the error '29' continues.  I also swapped the 'error 29' backplane into the working machine and it continued to work fine with its BV.

I don't know what else I can try at this point.  I'm going to sleep on it and hope it comes to me in a dream.  I switched everything that I can think of that would affect the BV communication - BV, harness, cash box switch, MPU, backplane

Anyone have any other ideas I can try???

Thanks,
Jim

did you try power supply? , we know the slot worked at one time

Mains??

board works in another game

Steve,

I took the MPU from the non-working BV machine.  put the game chips in for the working machine, did a clear and put back the mains and the BV worked - not great though.  I had to reseat the BV after the machine booted but at least it worked!   That has to rule out the MPU, right?

I also took the MPU from the working machine and put in the game chips from the non-working machine, cleared and put mains back in...still '29' error.

I guess the power supply swap is next!

Jim

As I said from the get go, It is very doubtful to be the MPU. You have an issue related to the BV assy.  Wiring, plug, Cash can, BV plug, door sw., or something else. Your biggest problem now, is that you're been looking at the same stuff over and over so much that you're missing something that a new set of eyes might see right off the bat. keep posting, maybe someone new will have an idea.

Jim,
    Just had a thought. How many red lights are lit on the front right side of the BV and how are the dips on the BV set?

This going to sounds nuts (since I'm nuts at this point)...I swapped the power supplies and the '29' error still appeared.  For some reason, I decided to swap the BV and coin box again....this time it worked - green arrows!!!   But it was not long lived.  I powered the machine off and them on. I could hear the BV but eventually the red light came on. I then reseated the BV and got the dreaded '29' again. I've reseated and swapped BVs and cashcans several times mixing and matching. Still getting the '29 error'.  It worked once so there's got to be something I can do to fix this thing

I didn't test the swapped out pier supply into the working machine yet

As for the lights on the BV, I'll have to check them when I get home

Thanks

During the joy filled period of green arrows, did you insert a bill?

Doh..no, I didn't try.  I was so excited about seeing the green arrows, I wanted to reboot the machine to see if it was just a mirage...apparently it was :)

There are two red lights on the BV no matter what machine I put them in.   All dip switches are off.

So I get home and for kicks I do another clear, reboot the machine and the BV works now...unreal.  :3-  I have no idea what actually fixed the '29' problem because I swapped so much stuff between machines.   I then take the other BV and box and put them back into the machine that was working...now that's giving me a '29' - ha!   I have a poker game next to that so I swapped the BV from the poker machine into the 6000...error '29'   I somehow transferred the error '29' from one machine to another.  :25-  It's OK for now since I'm getting this one machine, which is now working, ready for a buyer.  The buyer wanted me to add a TITO so I'm going to start that.

I'm going to end this thread because the urgency at hand has been resolved.   When I get to my other machine, I'll probably ask for so more help but I'm going to go through everything again before I post.  Hopefully the TITO installation will go smoothly (praying emoticon)

Thanks all for your help/suggestions

Jim

is the poker a bally or igt?

It's IGT

I think it might have been in acceptor housing. While back I had one gave me problem & fingers in housing was the problem. That's
why I suggested to change housing.
