My GMC shop manual lists four generators, standard, low cut in,
high output and low cut in/high output models. But I took the
easy way out when my standard generator failed and replaced it
with a 65 Amp one wire alternator. I charges while the truck
is idling at 450 RPM. I can replace it at any auto parts store.
I don't have to worry about the points in the regulator. Just
the right way to go for a daily driver.

If I'm not mistaken, didn't GM offer a high output generator in at least
the late 50's? I think the mining company trucks around here had them so
that they would keep up with the 2 way tube style radios in the winter.
These trucks idled a lot to keep the heat and lights going. It may have
been something as simple as a smaller drive pulley so the thing would turn
faster.
