I'm interested in doing this too, but don't know how it can work based upon how you have it wired. This rectifier has 4 wires - 2 for AC power and ground from the stator, and 2 for DC out and ground. You removed the stock voltage regulator and replaced it with the rectifier and capped off the DC out.<br/>
<br/>
The proper way to wire this is to disconnect the yellow stator wire and connect it to the yellow wire on the rectifier. Since the stator is internally grounded, you can connect the pink to ground. Connect red to the lighting circuit and green to ground. The Amazon listing says that this rectifier must be used with a battery to regulate voltage. I would wire a capacitor instead.<br/>
<br/>
Here's the wiring diagram that shows the yellow stator wire that would connect to a rectifier. Edit: Or even easier, if all you want is the headlight, just cut the black and red wires right at the headlight and splice the rectifier in. Splice in a capacitor on the DC wires to replace a battery.<br/>

First off let me admit right up front that I am pretty useless at electrical theory. I can figure things out if I research and study them long enough but as far as explaining anything but the easiest of electrical circuits it just isn't going to happen. As to why I hooked it up that way, I cannot remember why I did it that way and I suspect it was that someone simply said to do it that way and I did, and it worked, so case closed and I moved on to something else. Looking at your wiring diagram and your notes your way should work, however for whatever reason my way seems to be working as well which makes me suspect that the current is somehow getting smoothed out just by virtue of being connected to the rectifier. Not something I could explain off of the top of my head, but it is somehow doing it as my LED headlight now works whereas it didn't before I wired it up. I didn't add a capacitor either and it doesn't seem to need one. This rectifier does have a built in regulator so maybe the combination of rectifier/regulator all makes it work somehow.<br/>

Riding season doesn't start until Memorial day around here and when I can get out for a ride I am going to mess with the headlight/rectifier and take some notes regarding low idle performance to see if there is any flickering, etc. with my set up and then I am going to wire it up as you suggest and see if there is any noticeable difference anywhere along the rev range.<br/>
<br/>
Thanks for your input and if you find out the technical reasons why my way works I'd really be interested in knowing.<br/>
<br/>
Thanks,<br/>
