Alternator ailments resolved

[Kenneth Keith]

I have read the claim that the upper limit of voltage on the Bosch
regulator is too low to allow it to catch up or keep up with periods
of high demand (such as the radiator fan on full blast forever here in
the AZ summer heat, with other accessories on).  One such claim was
made on a website offering the external regulator conversion, so that
source is obviously not unbiased.  Here's one that isn't a commercial
page:  http://people.umass.edu/tcroy/articles/fordregulator.htm

I have noticed how warm the alternator and air shroud area can get,
which is quite warm given it's proximity to the turbo.  Maybe the
claim that high temperature adversely affects output is baseless.  I
haven't tried the external conversion yet, but I still find it
interesting.
