6. Setup and Installation
Proper installation is crucial for the correct functioning of the speedometer. Follow these steps carefully.
6.1 Mounting the Unit
- Choose a suitable location on your motorcycle's handlebars or dashboard that provides clear visibility and does not obstruct your view or controls.
- Use the provided mounting hardware to securely attach the speedometer unit. Ensure it is firmly fixed to prevent vibration-induced damage.
6.2 Wiring Connections
The speedometer comes with a multi-pin wiring harness. Refer to your motorcycle's wiring diagram and the following general guide for connections. It is highly recommended to have this done by a qualified technician if you are not familiar with motorcycle electrical systems.
- Power Supply: Connect the main power wires (typically red for positive, black for negative/ground) to the motorcycle's ignition-switched power source.
- Speed Sensor: Connect the speed sensor wires to the designated input on the speedometer harness. The sensor should be mounted near a rotating part (e.g., wheel, sprocket) to accurately measure speed.
- Tachometer Signal: Connect the tachometer signal wire to the motorcycle's ignition coil or ECU tachometer output.
- Fuel Gauge: Connect the fuel level sensor wire to the motorcycle's fuel tank sender unit.
- Gear Indicator: Connect the gear position sensor wires (if applicable and supported by your motorcycle) to the corresponding inputs.
- Indicator Lights: Connect wires for turn signals, high beam, neutral, etc., to their respective motorcycle circuits.
Ensure all connections are insulated with electrical tape or heat shrink tubing to prevent short circuits and corrosion.
6.3 Initial Configuration
After wiring, turn on the motorcycle's ignition. The speedometer will power on. You may need to configure initial settings such as:
- Cylinder Setting: Adjust the setting to match your motorcycle's engine (1, 2, or 4 cylinders) for accurate RPM readings. Refer to the operating instructions for button functions.
- Wheel Circumference: Input the correct wheel circumference for accurate speed and odometer readings.
- Time Setting: Set the current time.

7. Operating Instructions
The Geloo H-GJ001 speedometer is designed for intuitive operation. The LCD display provides clear information day or night.
7.1 Display Functions
The main display shows:
- Speed: Digital display in km/h or mph.
- RPM: Analog bar graph and digital display (x1000 RPM).
- Odometer: Total distance traveled.
- Trip Meter: Resettable distance for individual trips.
- Fuel Gauge: 6-cell indicator. The last cell flashes when fuel is low.

- Long Press: Enters setting mode or resets trip meters (depending on context).
To adjust settings (e.g., cylinder count, wheel circumference, time, units):
- With the ignition on, press and hold one or both buttons (refer to specific product instructions if available) to enter the setting menu.
- Use short presses to cycle through options.
- Use long presses to confirm a selection or adjust values.
- Exit setting mode by waiting for a timeout or confirming the last setting.

|---|---|---|
| No power/Display off | Loose power connection, blown fuse, faulty wiring. | Check power wires, motorcycle fuse box, and all connections. |
| Inaccurate speed reading | Incorrect wheel circumference setting, faulty speed sensor, sensor not properly aligned. | Verify wheel circumference setting. Check speed sensor connection and alignment. Inspect sensor for damage. |
| Inaccurate RPM reading | Incorrect cylinder setting, faulty tachometer signal wire connection. | Adjust cylinder setting to match your engine. Check tachometer signal wire connection to ignition coil/ECU. |
| Fuel gauge not working | Faulty fuel level sensor, loose connection to fuel sender. | Check connection to the motorcycle's fuel sender unit. Test the fuel sender unit if possible. |
| Display flickering or dim | Unstable power supply, loose connection, internal fault. | Check power connections. Ensure stable voltage from motorcycle. If problem persists, contact support. |
