I got this idea from 'buzztail' on the advrider KDX thread. With no modifications to the oem stator you can rectify the stock half-wave AC signal to DC for an LED headlight (leaving the rest of the system AC). Since the LED headlight uses much less current there will be enough left over power to run a brake light without having to float the ground on the stator.

Wiring diagram:

Rectifier/capacitor

Components used:

H6M LED headlight
AC to DC rectifier
10K uF capacitor
Mechanical brake light switch

I also swapped the rear bulb socket for an 1157 and wired the brake light circuit through the switch. So far its working like a champ on the factory stator. :rock:

If all you need is an LED headlight this will work fine, or you could just run the LED on the stock wiring without any rectifier. But if you're trying to make it street legal many states also require turn signals, hi/lo, and a horn which will quickly overtax the stock stator. Pick the setup that fits your needs.

It's still loading for me but I added a direct link to it from the "wiring diagram" text. If you're still having trouble shoot me PM and I can email it to you.

Hi henrys, I'd be interested in the wiring diagram please :-) (I can't PM you not sure why?)

working on making my KDX street legal ;-)

We have issues with the integration from time to time. It seems to be on paypal's side. You can always just send a PayPal payment to admin@kdxrider.net and include your kdxrider username in the message area.
