So i installed some new 12v led lights. When I first started the quad the lights turned on and worked until I put it into gear and started driving. Now the lights won't turn in any more. I put a normal florescent light and it works fine. I had my choke in and the bike was reving super high so I think that's why the lights only worked then. I read that the regulator makes the power from the stator a constant 12v but that doesn't seem to be true. Is there any way to make the power constant so the led will work or would I have to upgrade my entire stator?

 

No vehicle I know of has voltage stable. The regulator keeps it between about 13.5v and 14.5v with engine running as a rule. LEDs for vehicles are made to cope with this variation, so your problems are not due to that unless the regulator is overcharging (more than 15v) or the set up is AC lighting, which takes AC direct and un-rectified from a stator coil to the light switch, this doesn't do LEDs much good as they are pulsing on and off in time with the change from pos earth to neg earth of the AC coil, and the voltage is unstable, though most won't produce much over 18v as that would blow normal incandescent 12v bulbs too.

 

The quad does have a recetifer on it though. I've read that the stator is weak on these quads. So would It be the voltage is to low?

 

If it has a battery on it, the battery should keep the voltage above 12v until it goes totally flat, even if the stator isn't sending any power to the rectifier. Just checked a set of LED lamps on eBay at random, and voltage range they will work at is 9v to 32v. As I wrote above though, some bikes have AC lighting, this is direct from the stator. The way to tell is, if the normal bulb will light up with ignition and light switches on but engine not running, your lights are powered from the battery. If they won't light unless engine is running, you have AC lights and these are not suited to LEDs.

 

The mojave doesn't have a battery it's kick start only it gets power all from the stator

 

So I'm guessing that I would have to convert the ac power to dc power then. But the quad dose already have a rectifier on it so shouldn't it already convert it on its own?

 

"The mojave doesn't have a battery"

That explains all, without a battery the voltage will be wildly unstable, even if the lighting circuit is being fed DC, and there is no logical reason for Kawasaki to do so with incandescent bulbs, LEDs won't light until they get 9v. In fact, check the original bulbs are 12v as that "no battery" technology is from thee 1960s and many bikes had 6v lights back then.
