I'm confused about this transformer.
The tiny PCB the 120/240V switch was on has four wires out into the transformer (as previously mentioned). I assume and assumed these are the only primary windings.
What I recently realized is on the same side on the bottom is four wires (red, black, white, and yellow) that go into a connector and two yellow wires that go into another connector. These connectors go into a board with relays and regulators. On the other side of the transformer on the top are a few more wires but smaller gauge. Two connectors are red, red, and black. Another is yellow and yellow. On the bottom are more wires that go to two more four-pin connectors also red, black, white, and yellow thicker gauge.
Having wires on four points (top, bottom, left, and right) is making this confusing.
Ideally I'm quite confident this can be wired based on my assumption with the switch positions, but hoping I can make more sense out of this to be sure.
From what I mentally concluded, the worst case is: Since this will never be powered with 240, I wire the transformer in 240 mode in which case the power supply won't work. I've already concluded that the transformer needs to be connected in parallel,and traced the two windings, so this leads me to whether I can wire the phase wrong.
I expected the phase to be 180 degrees off when the primary is wired wrong and in phase when correct. Seeing the waveforms 180 off in both cases confused me.
