Hello Frank:

Hope you had a enjoyable Christmas.


I did, thanks. Did you have fun decorating the Joshua Tree?

Hello Programo5:

At 15 dollars each, and used sounds like there are not in premium shape.

It may be possible to have them rewound for a higher current, for
running a 4 or 8 pill amps. My 4 pill 2SC2789 amp will draw 75 to 80
amps with no problem.

A 105 amp alternator may have a higher peak current capability than
just 105 amps. I have never measured it but I would think it would have
say a 10 to 20 percent higher peak intermittent rating. Anybody know
about this or measured it?



The current rating is for a specific RPM which is typically high. The
current drops off to a bare minimum at idle which is why you sometimes
see the idiot light come on while waiting at a stop light.

Gee whiz Frank, I have never seen the idiot light come on while idling,
with a alternator.


I see you have never been a used car salesman. It happens more often
with carbeurated vehicles, rarely with modern fuel injection systems.


Why would it happen more often with a carburated vehicle?

Because of electronic idle speed control systems: a lot of carbs don't
have them while most fuel injection systems do. Without those systems
the idle can vary quite a bit depending on the temp of the engine
and/or air, humidity, altitude, pressure, etc.
