Grizzly front motor checklist for noises and/or error codes
Are there any error codes that appear on the bottom of the display?
Kindly turn off the power on the bike and disconnect the front motor cable at the connection point near the front wheel and send a close-up photo of each of the cable ends for reference, Please use a flash or shine a light on the cable ends so that we can clearly see the pin sleeves & pins in each cable end. Then when you reconnect it, please be sure the connection is fully seated and tight.
Please check the full visible length of the front motor cable for any signs of damage with special attention to the area where the cable enters the front motor. There is a spring covering the cable in that area that needs to be pulled back to fully check the cable so this is best done with the wheel removed. If any sign of damage is found, please send a photo for reference.
