Hey guys and gals,
First post here, but I'm a fairly accomplished scooter guy.
Here is my issue: Headlights keep blowing at higher revs.
Installed new stator a few days ago. been through six bulbs trying to figure this out...
Upon inspecting the bike with my meter, I find 13-14.3 volts at battery while running (terminals unhooked of course)
I'm getting 10-11V at idle on the headlight plug, low and high beam.
Rev it up and it jumps up to almost double voltage to 24V.
No resistance from any plugs to ground.
Should I assume I got a bad rectifier/regulator?
What started this all: stator shorted out. Replaced it, replaced rectifier also as the stator shorting caused the rectifier to go also.
Bike Model is a Taoto Lancer 150 Special Edition

Yep its your R/R no wonder it is blowing things out the highest safe DC from the R/R is under 15Volts. Optimal charge is 14.7 from a great R/R. Alleyoop

I wold suggest checking the grounds . Did you make any lighting changes before the trouble started ,change to led's change a light assembly with less bulbs ?

John John, No lighting changes, everything is stock, except CDI Its a blue no revlimit one. All grounds are good as all plugs green wire goes no Ohms to frame, at various points. Going to order a new R/R. Any suggestions? Its the four, flat, male prong type. Edit: somewhere that ships FAST... can't wait a week for my main ride to be down.

I have 4 pin regulators not the 4 across , I have the 2 over 2 and can provide wire layout and a plug . Feel free to call and I can get you all set up . Shipping is quick within the United States .
I'm thinking what you said grounds should be consistent . I'm thinking you may need to balance the ac and dc load to get the charging and lighting in range .

I can confirm it is most likely your RR. A couple of months ago I was blowing headlights every day. I got a new RR, and no problems since.

Thanks for the input guys, I have ordered a new R/R from forum sponsor partsforscooters and it will be here Monday. I look forward to being a part of this community and helping any way that I can.

Sounds classic for a bad R/R..definitely get a new one...but also check and see if your lights have a ballast resistor connected to them.. If so read how many Ohms it is rated at (it's stamped on the resistor) So if ya got one of those...check that as well.

Sorry for the tangent, but why would just the headlight blow? Would the other bulbs not be receiving the same voltage?

Question when you turn on the key your gauges work and your instrument lights come on is that right?

In my case, I blew 3 headlight bulbs without blowing any others before replacing the RR. No problems for several months since.

Just think for a minute WHAT can produce 24volts on a scooter? Two 12v batteries connected in series and the only other thing is the R/R which takes the Vac from the Stator converts it to DC to feed the lights as well as a wire to charge the battery. Now instead of checking the voltage at the bulb check the R/R wire coming out feeding the lights which is usually a yellow wire. Alleyoop

Only lights I can tell are powered by stator is headlights, so they are the only ones that blow because incorrect voltage coming through the R/R.

There you go the R/R is bad. Alleyoop
