Really, of course, this isn't Lucas' fault, since I'm dealing with a
non-Lucas alternator. Much continuing thanks to Randall and y'all for
all the suggestions.

I checked the voltage with hot test lead on BATT, ground test lead to
the case of the alternator. with car idling, voltage read 13 volts.
Up the idle a bit, and I got those little pulses again. Voltage went
to maybe 13.5 volts, at about 1 second intervals.
I repeated the same test with the test leads to the + and - posts on
the battery and got essentially the same thing. I did a quick
continuity check from the alternator case to the battery ground
cable, and it was a strong, quick signal.
I now maybe suspect either something fishy in the alternator, or in
the connector (little white plug for #1 and #2 on the alternator). It
seems to me to be a bit loose on there. I'm trying to source another
one to re-wire into the system to eliminate that as the possible bad
spot.
One other thought. Could the PO have missed something in the switch
to - ground? Might that have an effect?

at least it starts right up now, with a charged battery--hey, it's
something! :-)
