Turn the key, move the starter button up: CLICK. Do it again. CLICK. One more time. CLICK. Turn key off. Try again. CLICK. Again. VROOM.

Very very intermittent. Sometimes first time every time, sometimes you give up and pull the rope starter.

Loose connection?? Battery seems fully charged, so not sure.

 

Check the solenoid wiring and wire at the starter. If the starter is going south plenty of cheap ones here.http://www.dbelectrical.com/c-1789-polaris.aspx

 

I think sometimes they get dirt and moisture in where the starter button is too. That can cause you to get a poor connection and get the button to work intermittently.
