Question about ATVs
Major culprit is the rectifier/regulator and/or stator. The connectors get dirty from mudding or just dust and burn out the electronic components due to a bad or intermittent connection. Vibration and extreme environments will do that. The stator can be destroyed by brushing some grit into the oil fill while checking. Look at the wires, if any are burnt that's a tell tale sign. If it runs see if you are getting more than 13.5 volts. Could be as high as 15. It it's in the range of 12v or less while running the charging circuit if dead and you have the problems I described above. It's an expensive repair but there are after market websites for DIY"ers. I did one recently for $110 in parts. The dealer wanted $1000.00. Good luck.

Fuse, keyswitch. worst case CDI. grab a meter and start tracing power from your battery out.

SOURCE: My 2007 polaris 450 sportsman used to start with the pull start 2nd pull,now it starts for a couple seconds and stalls ,does this three or 4 x then starts and runs fine,by the way it won't start with
Could be time to replace battery, this is most likely the culprit. These fourwheelers are very picky when it comes to low power. Your starter is also most likely just fine, the clicking you hear is the solenoid on the starter, so your battery has some juice, but not enough amps to turn over the starter. Also If the fourwheeler has sat for a long time then you may just need to charge the battery. The 2007 is most likely fuel inject which uses even more fuel when running and it also has its own computer kind of like a PCM in a car or truck. These all need a good supply of power and the stator which is like an alternator usually needs the help of a fully charged battery to keep everything running properly. Also note, once you get a new battery or charge it in some cases the ATV should run smoother.
