No, no...
The motors never got to ground, but I'm now pretty sure
that I had the fields wired incorrectly between themselves.

(In fact, I'm still unclear on which is better - series or parallel)

Basically, I had them wired as neither,
while still having all the wires connected.
(but never to ground)

The motors *SEEM* to still be alive, but I cannot
tell about the Geckos until I rebuild the power supply.
