  That's true, especially with older alternators. Newer ones have
better abilities at idle than the older units did though, and I
believe there are some things that can be done with the windings
and such when building (or re-building) an alternator to increase
the output at idle. An "inexpensive" alternator, even though it
might be rated higher, probably needs to be spun to a higher RPM to
see the same charge that a more expensive alterator would
generate lower in the RPM range.

  Something that helped out with my truck was using a smaller pulley
on the alternator to speed it up at idle. Its a tiny little thing -
I'm not sure who made it, I got it from John Burgan a few years ago.
It did a good job of curing my charging woes at idle that were
caused by the underdrive pullies I installed.
