Re: [CAD_CAM_EDM_DRO] MPJA transformer wiring???

Jon,

Now it makes better sense. Hind sight 20-20? :) The yellow would just be used for 12v only secondary.

Almost certainly, you'd connect the two black wires together, the two

You would not connect the yellow wire. This would give you about
34 V DC on the filter capacitor.
