I'm puzzled. For sure my wall voltage is connected properly. My

I'm not seeing how hooking up the wall voltage to the slider doesn't
get me a stepUP transformer.


It does, but the core and windings aren't designed for that amount of
current, and will saturate. When that occurs, your input is looking at the
DC resistance of the winding instead of the inductive reactance of the core.

Just for fun, hook the AC main across both sides of the variac, use the
neutral as it is, and pull the AC OUT off of the slider, as follows:

Do you still have the problem when using that configuration?

That looks exactly like my configuration. And yes, I still have the
problem.
