Setup and Installation
Proper installation is crucial for the horn's performance and safety. If you are unsure about any steps, consult a qualified technician.
- Safety First: Disconnect the scooter's battery before beginning any electrical work to prevent short circuits or electrical shock.
- Locate Mounting Position: Identify a suitable location on your scooter for the horn. This is typically near the front, ensuring it is protected from direct impact and excessive moisture, but still allows sound to project effectively. The horn comes with an integrated mounting bracket.
- Mount the Horn: Secure the horn using its mounting bracket to a stable part of the scooter's frame. Ensure it is firmly attached to prevent vibration and potential damage.
- Electrical Connection:
- Connect the positive (+) terminal of the horn to the scooter's 12V power supply, typically through the horn button circuit.
- Connect the negative (-) terminal of the horn to a good ground point on the scooter's frame.
- Ensure all connections are secure and insulated to prevent corrosion and short circuits.
- Test Functionality: Reconnect the scooter's battery. Press the horn button to verify proper operation. If the horn does not sound, recheck all connections and wiring.
