2013 250R overvolting

[Neil E.]

Maybe an LED headlight bulb would have enough voltage tolerance to survive.

The advmonster h4 bulb is rated to 24v, cyclops doesn't say. LEDs are pretty tolerant though...

I should switch the headlight back on and see if it blows. I have a feeling its done this since new

I got a 24v truck bulb in mine now, that hasn't blown, not very bright though.

my 13 has a 2nd small pilot bulb below(nz)that used to be on even when main light switch was off,i never noticed if it stayed on when i switched the main bulb on also but if it did wouldnt it absorb some of the excess V?if its meant to run 2nd bulb all the time but its blown wouldnt that increase V to main bulb and maybe blow that too?do you have the 2nd bulb or different spec?ha!perhaps the 2nd small bulb is the factory cure for the overvolting problem?what about a couple of hid's if all else fails?

[Jakobi]

Do have the second bulb, and indeed its blown. I should replace it. I believe the switch has the option where to have no lights, the little bulb, or the big in hi/low. I could be wrong.

wont make any difference, small bulb stays on all the time and will blow that too.

Has anyone gotten to the bottom of this yet
I noticed mine is showing up to 40v on my trail tech when I rev it without the headlight on?
This can't be good for it

[Jakobi]

Negative! Mines still doing the same thing. Pretty sure it has done this since the day I bought it. 110hrs racked up now. Not sure if the bulbs blew from the same thing. I replaced the headlight, but never run it to see if it lasts.

Have you found a solution to this problem?

I'm getting over 16 volts on mine. I bought a led h4 bulb and it shuts off when i rev the engine. The regular h4 has not blown yet but i blew 3 small led bulbs.

My voltage regulator is an aftermarket one and was installed in april.
