I have a honda crf50 Pit bike that originally had no electrical other than what goes from the stator to the cda to sparkplug/ignition system. I found a tutorial showing how to rewind the stator to get power for lighting. Link
I did the mod and it works great. I actually over wound a few turns on each leg, so my output was a bit high. At low idle I get 10-12vAC+. While revving the rpms mid to high its up in the mid 20's, which is way too high to run on two 35watt 12 volt halogen bulbs(They'll just keep blowing). Instead of buying a voltage regulator like the one in the tutorial, i just used a 12v 2.2 amp Fixed Positive Voltage Regulator (Linear IC)
Yes this is 12v AC since I'm not running a rectifier.
I was running a 12volt 2" Red LED sealed mini clearace/marker light as tail light.Link
And it worked great, I made sure to leave headlights on at all times until i was sure it could handle AC and the regulator would hold.
I let my nephew ride it forgot to tell him not to turn the lights off. Of coarse thats the first thing he did. That and winding out 2nd gear, Fried the little light.
Do 12V LED fixtures like these, or any LEDs in general, care if its 12V AC or DC? (I know the Low Voltage halogen type bulbs do not.)
Is this regulator going to be ok for this application?
Do i need to add a rectifier inline to convert it to DC?
Thanks for any and all help.
