Magneto Generator Project

[Chicken]

Ever since I built my motorized bike, I’ve been messing with the white wire trying to hook a small light to it. I eventually gave up cuz it kept on killing the engine.

Instead of robbing power from the spark plug’s magneto, I decided to make my own generator out of some wire (from an old motor) and thin sheet metal.

After all that, much to my disappointment, I only got .32 volts out of it. Is there something I did wrong? Was the wire too thin? Did I ground it incorrectly? I’d really like this thing to work. Hope the pictures help.

thanks in advance for your replies

I finally took my bike out for a test, and the good news is that the generator produced a lot more voltage than my previous design. The voltage reading fluctuated A LOT but it averaged around 5 volts. The bad news however, is that it still couldn’t power my led flashlight. I also tried it on a small 3 volt incandescent bulb but still no go. At this point I’ll just stick with batteries Anyways, thanks for all who helped; maybe someday I can figure it out

Yea, those windings have to be very tight made form thin wire to be effective. Ebay- 10 bucks.
