Scott, I don't have great graphics skills, but:-

If you joined the primary and secondary 0V wires, you are left with a
three contact transformer!!

In your diagram the current for the load should go the other way.

Yeap, so it should!! My mistake!!

I still don't know what you're saying is wrong with my diagram

What!! Apart from me saying *it will not work!!*

In my diagram, the 1.5A primary current flows &only* in the primary
winding of the transformer and the 3.0A secondary current flows *only*
in the secondary.

Whereas in your diagram, *you* had both flowing in one part of *your*
coil, which would not work!!

No if's, no but's, no maybe's!!

The current flowing in my load circuit has to come from somewhere. Redraw my circuit, with the same transformer, showing where you think current flows.
