Does the electric starter work on the button? The neutral and reverse lights are low wattage and may be eathed onto the engine anyway. Check the earth leads, especially the one on the battery. The live lead from the regulator to battery can also cause this problem. It needs fixing as you could be getting high voltages to the lights, this can blow bulbs, or other electrical components, if they are getting high voltages.

the selenoid is removed but the button work when their is a working selenoid i need to order one... ( i think it work im unsure )


And for the voltage i tested while running and the voltage wont go over 14-15volt at 9/10 throttle on neutral so it charge well


The current battery is dead i start the atv with the crank for 2 years.. i need to replace the battery and put a selenoid


For the neutral and reverse light it work when turning the key with a good battery. or even this one

Even with dead cells in the battery,the voltage from the stator through the regulator has to go somewhere. It can attempt to go to the battery and may build it up enough to show the instrument lights when you turn the key on,but lights that work only while running are working from the voltage supplied from the stator through the regulator/rectifier. Like mentioned,just get a battery and fix what needs to be done before you possibly have problems from any voltage spikes.Depending on the vehicle, lights can be the first thing blown because they have the least resistance and voltage can hit them first,but other electrical components can be damaged also.

I did try with a working car battery and the front light where still off but the neutral and reverse was on...

I'd still just get the correct battery,install the new solenoid,then you can trace what problems you still may have. Auto batteries have caused problems themselves in the past on atvs especially if the auto is running because of the higher amperage. A lot of people have learned the hard way on this when coils,cdi modules and wiring have burnt.

may explain my 2 cdi burned on my chiness atv...


Uh i did try with a car battery but out of a car i mean i carried the battery full charge to the atv and pluggued
