Thank you for allowing me to join this forum. I am a newby when it comes to four wheeling. I recently purchase a 2008 Grizzly 700 FI and took it out today. I tried to engage the 4wd. When I press the red button (when I am stopped) I can here a sound. It sounds like a small electric motor. After that happens nothing changes on the display and it seems as if it is still in 2wd. I tried the diff lock and it flashes on the display with a red flashing dot. Not sure what to do next. Is there a fuse or something or someway to troubleshoot it. Thanks for any and all of your help!
