I have a 2006 Grizz 660. In the last year it has had starting issues. I replaced the relay and it worked for a while. Took it in and they replaced the relay again. Worked well for a month then would not start. Took it in again and they replaced the starter. Worked 2 months then stopped working again! Battery is good, fuses are good. When you push the starter it burps for 2 seconds like it wants to start then all I hear is the familiar click, click and nothing else. Any ideas?
