I have a 2006 660 grizzly and today when i was out for a run the 4×4 wouldn’t engage and no display indicator in the digital display. After a while googling the issue i see that others have had issues with the SERVO on the front diff. Theres no sound from the servo motor due to the 3A fuse under the seat blowing, i installed a 10A fuse just to check if the servo was working and it was working perfect. I then noticed there was a wire ground out on the A Arm coming from the connector from the servo, repaired it and issue still same. Switch on handle bar working fine also.Could it possibly still be the servo even though it engages with the 10 amp fuse fine? Any Ideas? Thanks
