An you send a pic of those steppers. I have salads. From eta and maybe able match them up.

Also check the schemetics .. they will show the coil numbers

Can't you upload a photo in this thread?

I just happened to have two Williams Kings and one was so beat, I parted it out. Box is up in the shed, so may take some time to dig out.

Also may still have a schematic. Coil numbers shouldn't be too hard to figure out. Williams steppers are pretty similar and universal in that era wherever they were used on the machines with only the usual functional differences. On Kings each letter "K" "J' and "Q" has it's own stepper mounted under the playfield I believe. Should be two coils on each one.

If you are patient, I will report back when I can on it.

I do not have a Kings schematic, but do have one for another 50V Williams of that era.

Typical step up coil looks to be A-26-1100, and step down or reset coil is B-29-1600.

Unless those are the same as the larger steppers that were used for the light scoring behind the backglass. But, if memory serves me correctly, those are the same as the smaller steppers also used in the replay, match, and ball count units.

If more info is needed, I will dig the box out of the shed when I get the chance.
