That's what Pat was talking about, slapping-on a voltmeter and going for ride. BTW, that's 100% legit...it's load testing, in-situ...just as valid as using top speed to estimate hp (seat-of-the-pants dyno). If voltage never drops below 13V @ 4000rpm, you should be fine, at the very least. These engines don't spend much time below 4000rpm, while riding.Feeding the LED HL off the battery and taking power from the yellow at the regulator has eliminated power drain throughout the bike. With 13.1v at the batt at 4K I suspect I’m going to be okay. Not sure what your thinking Allen but intrigued. I’m going to do some night riding and see what happens.
This is a garden-variety, half-wave reg/rec unit. Two inputs, yellow which it T-d + white...two outputs DC+ to battery & system ground (-). Honestly, I've no idea how AC voltage is regulated to the yellow HL circuit; whatever the method, it's going to be basic/crude-but-effective. On the charging (DC) side, there's likely ~1.5a current which isn't much more than what a typical trickle charger puts out...and very easy to control.im thinking about this. A buck regulator converts ac to dc. I may incorporate that into the ac to the headlight. Yes the ac did do HL and TL. I moved the tl to dc last year. The rest of the last 2 posts are over my head. The schematic is right out of the manual for a skyteam 125. That is the harness I’m using. The regulator is nothing special. A 4 pin regulator rectifier

I’m running led taillight and speedometer currently. The only incandescent are my signals right now
Led running/signal bulbs may be the cure. BUT.... what happens to the system with yellow wire at headlight disconnected. I don’t want to cause damage
I’m going to put this before the signals on the yellow feed
That's what i was gonna suggest right at the beginning. A diode in series will cut off half of the waveform ... but i really doubt it would be noticable, it may flicker a t low Rpm perhaps. Just make sure it's big enough to handle the wattage.One thought comes to mind...placing a diode in the headlight power feed.
