In college the professor spoke about this for about 30 seconds on the first
day and said "Now, for purposes of your education, current moves from
positive to negative." And we really never and an issue with it. Made the
homework nice and simple without thinking about electrons or holes or
anything else.
The only guys that seemed to care were physics majors, vacuum tube guys and
device physics/semiconductor design guys.

Subject: Re: [AFMUG] DC/DC converter question
It probably doesn't help that Electricity is actually electron flow,
which comes from the negative terminal. It all would have been so much
easier if they had called electrons positive, so that the actual flow
matched the theoretical flow.
Instead, some probably think of electricity flowing from the positive
terminal, when in fact it is the sink, not the source.

That was what I thought, thank you all for confirming.
However, with it connected red+/black-, when our tech flipped the breaker
it blew out the DC/DC converter. In fantastic order, I was told.
So I'm going to have them put a voltmeter to the wires and see what we are
getting from the power supply, maybe the output wiring is wrong.
