I got it.  Seems like a long way to go to avoid using an ohmmeter.

I was also not sure how much you can feel a shorted winding on a stepper
motor, since most have fairly strong detent forces to begin with.  I didn't
have a stepper motor handy to try on, so I kept quiet.  Your method also has
the problem of not determining polarity easily.  If you've got 4 pairs, just
tying one from each together will only work for 2 out of the 16 possible
combinations.

Then there's the question of why is someone messing with stepper motors that
knows so little about electronics that they have a phobia for ohmmeters.  Or
at least why would you want to put yourself in the position to support them.
It seems like a no-win situation.  When something doesn't work they'll blame
you.

It did make me think a little about how to automate this with a PIC.  Plug
in up to 8 wires from a stepper motor and a few seconds later it tells you
what's what.  Then I realized this would be a low volume product and the
same people that don't want to spen $15 for an ohmmeter aren't going to
spend $200 or more for a stepper motor tester when you can buy a new stepper
motor for $20.

I've also stopped responding to general requests for help ever since I found
out you were sensoring my posts behind my back and despite your promise not
to back in October.  I now only jump into interesting intellectual
discussions or when I otherwise feel like it or have something to gain
myself.  I don't want to "support" the PIClist with free help as long as my
posts continue to be subjected to sensorship.
