Jon-
Is that small alternator pulley smaller than a 2.5" '97+ alternator pulley?
Could you possibly measure the diameter for me and let me know? I just read
John Burgan's post saying it was a March pulley, I may give them a call.
Thanks a lot!
James

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.
