I am working on an arctic cat ATV and it is not turning over, there is power. it makes a click sound. i think the brushes on the starter may be bad, but i am not certain. can someone plz give me a place to start. @

2000 and 2001 are likely to be the same or close enough.

sounds like the switch may be shorted, or a wire(s) have shorted to one another.... Find the plastic connector for the switch and unplug it... it should not fire.. if it does.. maybe someone has hot wired it??? ... BE CAREFUL!!

They sound like power for lights, you can use a power meter to check for power. ............~~~~~*BB

#! fully charged - good battery with CLEAN terminals and wire connectors. Starter is easy to rebuild.. If its not starting..try gently tapping starter with a dead blow hammer while holding the starter button down, if it turns over.. rebuild the starter...NOW. Make sue all connections are tight..

Sounds like you have a bad cylonoid or starter brushes are bad

either battery is not fully charged, or starter or solenoid is bad.
you can jump the solenoid with a screwdriver if you know how. if that starts it then the solenoid needs changed.

The starter has to throw it's gear out using centrifugal force. The speed of the starter has to be enough to overcome the spring inside. It is either a little seized and needs to be rebuilt and greased up, or the battery isn't powered up enough to get the right speed to engage properly. In that case clean the battery posts and clamps well, then charge or replace the battery. To know if the battery is bad wait till it is charged... if it still doesn't engage try again with booster cables from your car etc. and see if it suddenly works fine.

Sounds like starter clutch is binding? Therefore turning starter while riding, then it will melt!

replace starter
