What Causes the Invisibility of Motorcycle Gear Indicator?
1 Answers
When the motorcycle gear indicator is not visible, it is usually due to a burnt-out small bulb inside the instrument panel. Replacing it with an LED will significantly extend its lifespan. You can test the functionality by touching the gear wire to the ground and checking if the display works normally. If it doesn't, the issue lies with the instrument panel. If it does, the problem is likely with the switch's poor contact or damage. Gear Indicator Display: The motorcycle gear indicator display mainly consists of the gear display unit, the lower gear display switch, and connecting wires. Its structure is relatively simple, making repairs quite straightforward. Although the lower gear display switch may vary in structure and appearance, its working principle is very simple: it uses the transmission to drive internal contact plates that correspond to each gear, transmitting the signal to the gear display unit. Precautions: When replacing the lower gear display switch, it is generally necessary to remove the small flywheel cover. Some models may require removing the magneto cover, while three-wheeled motorcycles might need the reverse gear unit removed. However, the process is usually not difficult—it mostly involves unscrewing bolts and requires minimal technical skill, making it feasible for DIY repairs. It's important to note that for externally exposed contact plate types, ensure the plate fully engages with the transmission drum socket during installation.
