I have not put together the rectifier yet.
But I still believe the switch is wired wrong, e.g. when it is set to 230V, the primary is set to run in parallel, when it is set to 115, it runs in series. @1.21Gigawatts, wouldn't you expect the RMS voltage to be higher when the primary runs in parallel as opposed to serial? Because that is what I am measuring now:
switch set to 230V: 10V
switch set to 115: 5V
So while the switch is technically not wired wrong, it is showing the wrong voltage. I would need to turn it 180° so that the correct voltage would show.
I hope I am making this clear... I could take a picture of the board and components, if that helps.
