5.2. Wiring Connections

Connect the wiring harness to your motorcycle's electrical system. Refer to the following general wiring guide. It is highly recommended to consult a professional for wiring if you are unsure.

• Red Wire: Positive (+) power supply (usually connected to ignition switch).
• Black Wire: Negative (-) ground connection.
• Green Wire: Speed signal input (connects to the speed sensor).
• Blue Wire: RPM signal input (connects to the ignition coil or ECU).
• Other Wires: May include connections for indicator lights (turn signals, high beam, neutral), fuel level sensor, etc. Refer to your motorcycle's specific wiring diagram for these connections.

For a visual guide on installation and initial setup, please watch the following video:

6. Initial Setup

After installation, you may need to configure the speedometer settings for accurate readings. Use the button on the unit to navigate and adjust settings.

6.1. Accessing the Settings Menu

To enter the settings menu, turn the ignition ON while simultaneously pressing and holding the button on the speedometer. Continue holding until the settings menu appears.

6.2. Adjusting Settings

• Tire Circumference (C-xxx): This setting calibrates the speedometer to your wheel size. Use the button to adjust the value to match your tire's circumference in millimeters.
• Number of Magnets (P-x): Set this value to the number of magnets installed on your wheel for the speed sensor.
• Cylinder Type (2 or 4 stroke): Select the appropriate cylinder setting for your motorcycle's engine (e.g., 2 for a single-cylinder engine).
• Fuel Sensor Type (E-x): Configure this setting to match your motorcycle's fuel level sensor type for accurate fuel gauge readings.
• Odometer Reset: If needed, you can reset the odometer through the settings menu.

The installation video in Section 5.4 also demonstrates how to navigate and adjust these settings.

7. Operating Instructions

Once installed and configured, the speedometer will display real-time information. The button on the unit allows you to switch between different display modes.

7.1. Display Modes

• Odometer (ODO): Shows the total distance traveled by the motorcycle.
• Trip Meter (TRIP): Displays the distance traveled for the current trip. This can usually be reset.
• Speed (KM/H or MPH): Indicates the current riding speed.
• RPM: Shows the engine's revolutions per minute.
• Fuel Level: Displays the current fuel level.
• Voltage: Shows the motorcycle's battery voltage.

7.2. Switching Units (KM/H vs. MPH)

To switch between kilometers per hour (KM/H) and miles per hour (MPH), navigate to the odometer screen and press and hold the button until the unit changes.

7.3. Display in Action

8. Maintenance

• Cleaning: Clean the display screen and unit housing with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the surface.
• Connection Check: Periodically inspect all wiring connections to ensure they remain secure and free from corrosion.
• Sensor Check: Verify that the speed sensor and magnets are clean and properly aligned.

9. Troubleshooting

• Display Not Turning On:
  • Check the power (red wire) and ground (black wire) connections.
  • Ensure the motorcycle battery has sufficient charge.
  • Verify any inline fuses are intact.
• Incorrect Speed Reading:
  • Confirm the tire circumference setting (C-xxx) is correct for your wheel.
  • Verify the number of magnets (P-x) is correctly set.
  • Check the speed sensor installation and ensure it is properly aligned with the magnets.
• Tachometer Not Working:
  • Ensure the RPM signal wire (blue wire) is correctly connected to the ignition coil or ECU.
  • Verify the cylinder type setting is accurate for your engine.
• Fuel Gauge Inaccurate:
  • Check the fuel sensor type setting (E-x) in the menu.
  • Ensure the fuel sensor wire is properly connected.
• Cannot Switch Between KM/H and MPH:
  • Ensure you are on the odometer screen. Press and hold the button for several seconds until the unit changes. If it does not change, re-enter the settings menu to verify if there's a specific setting for this.
