Installation and checks

• Switch off the scooter and disconnect the battery as instructed by the manufacturer. Photograph the connector and position of the original assembly.
• Position the clamp so the throttle returns freely to its resting position. Align the connector keyway, avoid forcing contacts and keep the cable free of pinching.
• Check the display, key-operated power, throttle response and motor cut-off when braking before riding. Have a technician inspect mismatched connectors or communication faults.
