Okey dokey, now we got some discussion going! Not sure where in this thread there was
a mention of a regulator being polarity sensitive but lets run with that though any way.
Since the Delco-Remy three unit regulators were simply DC operated relays, why would
it make any difference if the current thru the coil was in one direction rather than the
other???
I can understand your concern if we were talking about a solid state voltage regulator in
an alternator but I can't see where it would make a difference in the type that were using
in the fifty vintage trucks.
