Ive replaced the battery, the key switch, the solenoid and still nothing. I can jump the solenoid over with a screw driver and turn the motor over but no spark. The lights wont even come on. Where could it be?

 

so you've replaced the keyed ignition, right? ok, have you checked out the wiring for continuity from the key down to the solenoid area? have you checked the inline fuse there at the battery if equipped? the brake switch on the left handlebar must work. it's a safety interlock. even if the brake light doesn't work, the switch must activate to satisfy the interlock. you should be able to hear the switch make a "tink" sound when you squeeze the brake lever. of course, if the brake light illuminates, then you'll know it's working.
if equipped, does the rear tether kill switch work?
satisfy the interlocks and it should turn over with the starter button with a fully charged battery.
get an ohm meter/voltmeter, you don't have to have an expensive one, one of the $5 harbor freight meters will work. check for continuity on the ignition wiring down from the key, to the battery, solenoid, starter, circuitry. be patient, we'll help you find it.
P.S.
next time you post, put the thread in the kids atv section or the chinese section. it'll get replies faster in those forum sections. sorry for the delay, i just saw this post this morning.

 

Sorry I'm late Jaster, got a lot of irons in the fire. I checked that switch with an ohm meter and it was bad. I replaced it with a new one, but it still wont do anything. The only other safety switch that and can see is the transmission neutral switch, which could be bad, or maybe the safety box? The solenoid had came loose and got into the chain. I wander if this shorted these out?

 

now which switch was bad and replaced? the brake switch? sure the neutral switch could be bad also. did it have an inline fuse at the battery? did it have a tether kill on the rear below the seat? safety box i'm not familiar with. sure, you'd have to ohm out the wiring on that safety box. turn the key on and start ohming the circuits as the electricity would normally flow. battery to key back to solenoid to starter, etc.....

 

to be sure the inline fuse should be good if you can "cross jump" the starter..........have u checked the voltage coming from the stator?

 

Does it have a remote control for killing the power if the kids get into trouble? If it does there is a box under the seat to control this. Unplug it and see if that works, it did on my son's one and it had no spark until I unplugged it, then got spark and not a problem since, but no more remote kill switch! Hope that helps.
