Don't forget to polarize it before you try to use it. I spent
many frustrating hours with a meter trying to figure out why my
brand-new dynamo and brand-new control box still couldn't make
that warning light go out. I woke up one Sunday morning with
the thought "why did my voltmeter reading have a minus sign in
front of it when I tested the dynamo output? ...Polarity,
dammit!" Went out in my pajamas and polarized the puppy before
breakfast and everything worked fine after that. An analog
(moving-coil) meter would have made it obvious from the
beginning. Another argument for low-tech!
