5. Installation Guide
Follow these steps carefully. If unsure, consult a professional.
- Prepare the Scooter:
- Ensure the scooter is turned off and the battery is completely disconnected to prevent electrical shock or damage.
- Place the scooter on a stable surface.
- Remove Old Components:
- Carefully locate and disconnect the wiring for the existing throttle, display meter, and controller.
- Unmount the old throttle/display unit from the handlebars and the old controller from its housing. Note the routing of all cables.
- Install New Controller:
- Mount the new 48V Controller in the designated location on your scooter. Ensure it is securely fastened and protected from moisture and impact.
- Begin connecting the main power cables (usually thicker red/black wires) from the controller to the battery.
- Install New Throttle Display Meter:
- Mount the jx-100 Throttle Display Meter with Key Switch onto the handlebars in a comfortable and accessible position.
- Route the wiring from the throttle/display unit to the controller, following the original cable paths to prevent pinching or damage.
- Connect Wiring Harnesses:
- Connect all corresponding wiring harnesses between the throttle/display unit and the controller. This typically includes:
- Motor phase wires (often thicker, colored wires)
- Hall sensor wires (smaller, multi-colored wires)
- Throttle signal wire
- Brake signal wires
- Key switch power wire
- Display communication wire
- Light/horn wires (if applicable)
- Refer to the wiring diagram on the controller label (Figure 2) for specific connections. Ensure all connections are firm and correctly seated.
- Connect all corresponding wiring harnesses between the throttle/display unit and the controller. This typically includes:
- Secure and Test:
- Once all connections are made, secure any loose wiring with zip ties or cable wraps to prevent interference or damage.
- Reconnect the scooter's battery.
- Turn the key switch to the 'ON' position. The display should light up.
- Carefully test the throttle, brakes, and display functions while the scooter is on a stand or with the wheel off the ground to ensure everything operates correctly before riding.

6. Operating Instructions
- Power On/Off: Insert the key into the key switch on the throttle unit and turn it to the 'ON' position to power on the scooter and display. Turn the key to 'OFF' to power down.
- Throttle Control: Gently twist the throttle grip to accelerate. Release the throttle to decelerate.
- Display Functions: The display meter will show various information:
- Speed: Current riding speed.
- Battery Level: Indicates the remaining battery charge.
- Mode (M button): Press the 'M' button to cycle through different display modes or riding settings (e.g., Odometer, Trip Distance, Speed Modes).
- Power Button: May be used to turn the display on/off independently or to adjust settings within a menu.
7. Maintenance
- Keep Clean and Dry: Regularly wipe down the throttle display and controller with a dry, soft cloth. Avoid using harsh chemicals or excessive moisture.
- Check Connections: Periodically inspect all wiring connections for tightness and signs of wear or corrosion. Ensure no wires are pinched or exposed.
- Environmental Protection: Store your scooter in a dry, temperate environment. Avoid prolonged exposure to direct sunlight, rain, or extreme temperatures.
