has 1000miles no repair history other than regular oil changes,cable lube,air filter
all done at the dealer where I got it its been perfect until now

Answer
Hi Scott,

Continue performing electrical diagnosis. I'm suspecting a safety switch may be the cause.

Safety switches are often used on clutch and side stand (on motorcycles) and neutral.

If you've installed a tether kill switch on your Griz, check it fro proper operation.

Check entire ignition circuit wiring, connectors and components. All must have resistance or Ohm values within service limits.

Visit this website message board and ask other Grizzly owners if they've experienced the same problem:
