I have a 2002 grizzly 660 and when i turn the key on, all displays and lights come on. When i I press the start button I get a buzzing sound from the starter relay. I'm pretty sure there is enough juice in the battery. I tried putting a screwdriver to connect the two input/bolts on the starter relay for a second and saw a spark but nothing happened. I never heard the starter. Is there something going on between the relay and connections to ground/engine and/or starter? Any ideas? This is my first post so any feedback is welcomed. Thanks.
