On the average car, anything above idle is 13.8 to 14 miles per hour. I
said 60MPh because usually at that speed you are on a flat plain road and
you are in a fairly low gear. And some new alternators actyally have a
good regulated output. The real real old cars used to just use the battery
to ballence the output, but, they only put out 10 to 11 volts in the first
place... :) (those were generators)
