I hadn't thought of that. Good point. Another problem is that "worst case"
diagnostics won't necessarily be worst case anymore.

Sigh. It looks like *quite* the challenge.

Any idea how to estimate the gauge? I know I'd need red and green enameled,
perhaps another color like yellow? I also wonder what they used to insulate
the splices? It appears to be some kind of paint.

True.

What size nuts?

Oy! The core circuit that I copied for my 12th-grade drafting project used
7.5VDC as the half-voltage. How much oomph would it take to induce a stable
magnetic pattern in a steel nut?!? I would think that enameled insulation
would cook right off the wire.
Anyone with a EE degree and a copy of Spice care to take a stab at it?
