This section addresses common issues you might encounter with your Fardriver Controller.

7.1 Controller Not Powering On

• Check the main battery connection and ensure the battery is charged.
• Verify the ignition/key switch connection if your system uses one.
• Inspect all power wires for damage or loose connections.

7.2 Motor Not Responding or Intermittent Operation

• Ensure all motor phase wires and Hall sensor wires are correctly connected and secure.
• Check the throttle connection and functionality.
• Review programming settings for any active error codes or incorrect motor parameters.
• Confirm that no connection plugs are missing, as reported by some users. Ensure all necessary connectors are in place.

7.3 Limited Performance (e.g., lower top speed)

• Access the programming software via the Bluetooth dongle.
• Check the current limits (battery current, phase current) and speed limits. Adjust them according to your desired performance and motor/battery capabilities.
• Ensure your battery can supply the required current for peak performance.

For persistent issues, consult the detailed programming guide or contact customer support.
