I have an 04 model 450. I started it fine, just hit the electric start, no throttle, and it started and idled fine. Ran 30 seconds up the hill to my uncles place to ride. Cut it off, went in the house, tried to start it up again and it just clicks one time, not rapidly like a raffling noise. Just hit the start button and one click, no more, until you hit the button again. Sometimes the starter cranks very slowly and then the solenoid just clicks again. Almost like a loss of voltage to the starter. Also, sometimes when I would go to start my quad, I’d turn the key and the neutral light would not come on at as well as nothing else. I would just keep turning the key ignition until it did. Same deal with the electric start. When I would switch it to run it would do the same thing. Wouldn’t do anything. So, I would just do the same thing I done with the key ignition to the kick switch, which is just keep switching from off to to run until I heard the relay click under the seat and then it would crank perfect. If anybody could suggest what to look at first it would be appreciated.
