Power-one supplies (I feel stupid...)

[Jim Johnson]

Oh, I see; the grounds for the 5v and 12v supplies are separate. Of course
I got 0v on the + and - 5v connections; they are floating with respect to
the 12vc supply.

Thanks for the tip! This supply is well built and the docs are good, except
for this one little oversight.
