Testing a 3WA wallbox

Hi, I'm about to start tearing into my v 3WA wallbox. Upon initial inspection, it's missing about a dozen screws and the contact blades are completey black from all the dirt. The Button assembly is loose and the return spring for the lever that snaps the standby, credit and run switches is just hanging in the air.

I had it selecting but it was 1 number group off for all selections and for every selection selected, b1 would also play.

With that return spring now attached, the wallbox put the stepper into a frenzy and caused it to select a million selections until I pulled the 3WA selection receiver plug.

I plan on taking the 3WA completely apart to cleAn everything and adjust all the switches etc... And I don't want to make the stepper go crazy again when I attempt to test it when I am ready to put it back together.

So my question is this... Can I detach the signal wire inside the 3wA that goes to the selection receiver and get full functionality of the wallbox without having communication to the stepper?

Thanks in advance for any and all help.

Jeff, you can disconnect the blue wire to keep it powered w/out activating the stepper.

Are you talking about the leaf blades directly behind the wafer...or the blades under the motor?

A couple of pictures would be worth a few hundred words here.

The button assemblies are held from behind the front plate with two screws each. Some buttons will have to be removed.

Hi Rob, thanks for the update....

Boy they certainly didn't make these leaf switches very accessible for adjustment did they when they designed this equipment.

I was talking about the leafs directly behind the wafer, I had cleaned them and thought I adjusted them when I put that spring back on with hope that that was throwing the number group off. however I just noticed that the cam I was using to determine when it fell into credit position was the wrong cam lol. One Cam has a birds mouth and the other cam has just a single point and I had them backwards in my adjustments. I'm going to have to use a magnifying glass and a high watt desk light in order to do this surgery lol.

Hi Jeff,
IMHO, the reason they are "hard to adjust" is that they don't need no stinkin adjustments, iffin nobody attempts to adjustz them !!!

Hi Ron, I hear ya.... That's how I feel about my Mechs.... With the Mechs, I usually remove them from the machine and degrease them really good before I attempt any mechanical adjustments... More often then not most adjustments are right on or really close to where they need to be.

I have been buying up wallbox's and wallbox parts for some time now, I probably have 2 - 3W1's and at least 7 or 8 3WA'a all in various forms or disrepair.

I have had the pleasure to have purchased at least 2 3WA'a in a locked up state with no keys and when I actually got inside of them I found out that they were completely gutted and were now modified in such a way to be a conversational night light lol....

Note to self, If they don't have a key and its locked, expect the worst and make sure that you only pay an amount equal to what it would be worth to you if it was completely empty.

So, most of these boxes have been purchased as parts boxes... whereas I bought the back piece, then I bought the cover, then I bought the credit unit etc...

My 2 nicest looking and somewhat complete 3WA units have perfect chrome and really nice buttons etc... but unfortunately they have PCB boards in them instead of the Seeburg credit units. these 2 boxes were refurbished by RJB Restorations and were put on location in a diner in Las Vegas., I will save those 2 units for last lol.

So, Not knowing the history of any of these parts and having such a mishmash of parts that have all been thrown together, I feel I need to understand and go thru each step of their process slowly and completely in order to make sure that mechanically everything is opening and closing etc... as it should be.

At the end of this exercise, hopefully I will have a decent understanding of how these boxes are intended to work.
