I don't know if this would work for all alternators, but on mine I pretty
much solved this problem by adding a resistor across the 'ignition' lamp on
the dash. If memory serves, it was 4 ohms, 5 watts (mostly because that's
what I had in the parts bin). The resistor also ensures that the alternator
will continue to work even if the bulb burns out. With the resistor and an
original pulley, my Ford alternator 'kicks in' as soon as the engine fires,
and will put out enough at idle to keep up with either the Xenon headlamps,
or the radiator fan (but not both). I've noted that my 1980 Chevy also had
such a resistor built into the wiring harness.
