Can someone advise how to measure output from a bike generator/dynamo ?
This is the type that clamps onto the seat stay and is meant to rub the tire for the generating action. It's labeled 12V, 6W, Made in Japan. Two terminals, H and T.
I've hooked it up to a meter and the only setting that gives me any sort of reading is AC volts with either H or T and to what I assume would be chassis ground. That gives me between 3.7 and 4 volts when I spin the unit with a cordless drill.
Is this thing functional or not? And what would be proper wiring connections for it? Many thanks!
