Thanks, that's a good idea.  Now it seems that the diode may be
necessary for reasons other than "operator error".  In Nic's last
message, he mentioned:

If the diode is needed to catch these negative spikes, I guess I'll have
to go the series route.  Otherwise, I can do what you're saying to
protect from reverse wiring.
