trying to resurrect a Seeburg ED 3WA 22

Hello,

I have a consolette Seeburg ED 3WA 22, with a Dual Pricing Unit.
Got it powered with a transformer, but unfortunately, water get it's way in the coins hole. Coin switches are rusted.
So I cannot use the coin mechanism, so I would like to convert the consolette to freeplay and later use it with a WiPod.
I'm trying to understand how it works...
How can I make the contact arm position goes from "rest position" to "credit position" without moving manually the motor wheel ?
I tried grounding leafs from "carry over switch", if I make a short grounding it get in credit position, but if I stay grounding it make a full circle !!!

Any would be very great.
Sorry for my approximative English (I'm French), I'm trying to describe as much as I can, but if that's best, I'll make a video.

I do have a manual with 16 pages. Don't know if it's complete.

Best regards,
Serge

Serge, in this pic: http://s1192.photobucket.com/user/Rob-N ... rt=2&o=181 -I have shorted a lead to chassis ground using gator clips. This will make it step up and when two buttons are pressed it will launch normally.

Grounding either the black or orange lead on the credit unit will work here.

If you want to make this permanent I suggest you manually advance the white credit wheel a few notches by turning it counterclockwise so that the box steps-up to credit position and the credit lights are on, press two buttons and, as the machine is operating see which cancel coil pulls-in. Then simply disconnect that coil, and advance the credit wheel again. Now the box will always remain credited. On the box shown in the pic, the cancel coil is the one on the left with the gator clip on its frame.

Note that this box was hacked-up by someone before I got it and there is a coil missing. However the concept to free play it is the same.

Hello Rob,
Thanks a lot for your very detailed reply.
I had found the trick for the credit light, but wasn't able to find the way to turn into free play.
Thanks a million times, I've just test it and it works great.
You're an ACE !
Now it's time for me to clean this WOM and convert it to wiPod, should be very easy now.
Thanks a gain,
Serge.

I'm back again, with a trouble...
Here is what I have done :
I though I could disconnect the coil by unsolder the white wire, but I was wrong.
And I had difficulty to unsolder, so maybe it heat up too much ?
So I finally have resolder white leads, but now freeplay doesn't work anymore.
If I ground orange lead, it stops before a full turn. And if I remove ground, it goes back to "rest position".
If I ground black, it goes back to "rest position", not "credit".

Any idea what I can look for ?

Thanks for any help, I was close to accomplish it.
I'm despaired

I've done some continuity test.
I found that White / Orange leads or Black / Grey leads on the DPU leads gives continuity if I touch grounding (WOM frame for instance).
Am I right thinking this is not normal, as when I do it with other colours I have no continuity ?
Is the cancel coil shot ?
Do I have a chance to find a solution ? as I have no spare parts available...

Thanks for any help.

Despaired Serge.

Serge,
Spare parts are available--see the posts above for suppliers--
Ron Rich

Thanks Ron for pointing me to the list.
But before requesting a new coil, I'd like to be sure that it's defective ?
How can I check it ? Is my diagnosis good with continuity test ?
Also, I haven't figure how to remove it, screw is behind, I have no access to it, any idea how to remove coil from WOM ?
I'd like to avoid making a new mistake...
Serge.

Serge, I am not clear as to what has happened here.
Disconnecting a coil in the credit unit should not have any effect on the ability of the box to start once the credit wheel is turned a few notches counter-clockwise (credited position).

I can not see why you'll need any parts for this box. You have probably disconnected a wrong wire or moved a contact.

It is easy to remove the credit unit in order to change/adjust coils, etc.
There are two Phillips screws at the midpoint of the left and right side of the credit unit. The unit then is just lifted out from behind the chrome support for the page assembly.

Later today I'll go back into a wallbox here and try to figure out what might have happened in your situation.

Do NOT despair, these are simple problems. have another look at the wallbox diagram link:

Hi Rob-NYC,

I don't understand what's wrong...

With white lead (cancel coil) removed from DPU (but same happen if resolder to DPU:

Black lead grounded --> it make a full circle but doesn't goes to credit position, only rest.

Orange lead grounded --> it stops before a full turn (see photo). And if I remove ground, it goes back to "rest position".

I can't manage to get the free play anymore. What should I look for ?

Thanks for your precious help.

Serge

Hi Serge,
Do you have the Service Manual for this item ? If so, is the wiper set as per instructions, is the "carry over" switch set the correctly ? If both are properly set, I would assume that either the inner wiper is not making good contact with the inner brass "plate" on the wheel, or, that the plate is no longer connected to ground (earth) ? Ron Rich

Hi Ron Rich,

I have re-checked "carry over" switch like stated in the "contact arm position" in the manual. "V" form is perfect.
I also cleaned contact, no major improvement.

How do I check for grounding of the plate ?

Again, thanks a lot for your help.

How did you "clean" that contact-?? -measure the plate to the chassis--In this photo, it appears as if the wiper is in the normal,nn credit position ? Ron Rich

I used some french product called "miror" to clean "brass" and then used Alcohol to clean any residue.
Yes wiper is in "rest position".
I have to manually push it to "credit position" to be able to push selections buttons.
Sorry, not sure to understand what you mean by "measure the plate to the chassis" ?

See " contacts, how to clean" above--in the jukebox announcements section.
If you have credits established, you should not need to "push" the wiper--"
Measure in ohms from the wiper plate to the chassis--should be zero resistance--
Ron Rich

No resistance :-\

If I ground (for a short time, only a small touch) the wiper plate, it goes to "credit position".
And if I stay grounded it goes full circle.
In case it's a useful info ?
