To complicate things, in charging systems that were popular around the '80s
brush failure would not turn on the charging/battery light because the
current to turn the lamp on had to go through the brushes via the regulator.
My '85 Volvo and the '84 Nissan I had were like that. More modern systems
(including '91 Hondas, I'm sure) have a separate sensing circuit and don't
have that blind spot.

I concur - the alternator is very likely the problem, and the brushes (worn
or oily) are the prime suspects. I also agree that the alternator may test
okay on the bench depending on whether the intermittent is on again or off
again.
