Re: [CAD_CAM_EDM_DRO] Transformer wiring (for CNC controller, of course)

Looks to me like the Red-Yellow-Red is the centertapped Secondary, The #22,
probably the 12V windings, and I suspect the 16 ga are the 120/240. They
may be tapped for some odd voltage. Do a continuity & polarity test on the
16's, then do a turns-ratio test to determine the taps. Contact me off-line
if you still need help
