Ok i was holding a 2004 Honda Sportrak 400ex 4 wheeler for a friend and it ran just fine when i got it. of course ive rode it and what not and everything was fine. Then i went to start it and when i turned the key over theres no power at all so it wont start though i can push start with popping the cluth and everything will work fine. but then again when i turn it off theres no power. What could this be? PLEASE HELP

 

Dead battery. Did you turn the key off to shut it off or with the kill switch. Sometimes if you use the kill switch you can forget to turn the key off.
Try charging the battery.

 

Blown fuse???? If the lights don't work when it is running, it is the fuse. Only the lights and starter are on the fused circuit....
