What is the reason for the non-rotation of the Santana speedometer?

If it is a mechanical transmission odometer, improper assembly or incomplete transmission core engagement may cause the numbers not to turn. Plug line open circuit: The car speedometer may not work due to reasons such as a loose connection of the speed sensor plug or an open circuit in the wiring. The car speedometer consists of two meters: the tachometer and the speedometer. The tachometer directly displays the instantaneous speed of the engine, providing the driver with a basis for gear shifting. The engine speed is not allowed to reach the red zone of the tachometer, otherwise it will damage the engine and affect its lifespan. Electronic speedometer malfunction: Input a pulse signal to the instrument. If the speedometer needle rotates at this time, it indicates that the instrument is normal, and the fault lies in the sensor reed switch tube or magnetic ring. If the speedometer needle does not rotate, it indicates a fault in the instrument or connecting lines, and further fault diagnosis can be performed.
