I used the original alternator and hooked it up like the auto schematic, but
I found that when I turned off the excitation lead, (connected to an
over-voltage shutdown), the alternator kept alternating!!  The answer turned
up in a back issue of "Contact" magazine.  I will look up the issue/page if
you like.  It shows where to break one of the internal connections so that
the field power is controllable externally.
