Re: Magneto-powered headlights
I made my headlights using the white wire from engine to charge a 6 volt
12 amp hr battery. The white wire first goes through a diode which turns it into DC current. The diode then goes to an on/off switch to prevent overcharging when off. When on, it charges the battery. The battery then connects to an on/ off /on switch that controls two headlights from the old style wheel generator style systems. One for low beam and both for high beam. The battery then is actually running the headlights, with the engine acting as a trickle charger. I'm estimating about 1-2 hrs of run time on high beam before the battery drops too low. I've swichted out the 3 watt bulbs for 10 watt ones which puts out lots of light, but after 300 miles of riding,
I have'nt used the lights enough to know how long I can run them.
