"Refering to G4XNH and others:
The alternator's output power is depending on the rpm of the motor. If the
motor is running idle, the alternators output is not enough to power all
the electrical consumers in a car, i.e, with headlights on (which is THE
main consumer of current) the battery is supplying most of the current
needed and will eventually be empty.
This changes as soon as you are driving with rpm over 2000 or so
(depending on the car you drive and the number of electric consumers)."

I neglected to mention the fact that even though I continuously revved the
engine up hard to much higher than normal revs (Even slipping the clutch
when slowing down) entirely failed to prevent the engine stalling. In all
three cars that I tried this experiment, NONE would stay running once the
main beams were switched on. Even if I switched them straight off again, I
could not prevent it stopping. It was apparent that too much current drain
was made and the alternator just could not supply what was required. Of
course this was some years back and Patrick might be speaking of new
models which MAY have an increased alternator output. However, it is my
experience that as modern technology gets "better" through the decades,
short cuts are taken to cut the cost and against "better" advances in
other directions, whatever the product, less is the result rather than
more in some directions so this my experiments may still apply even now.
Perhaps someone would like to try this experiment on several more modern
cars and report his results? I would certainly be interested to see if the
same applies now after some 20 years or so ago when I tried this.
