Ignition system Hall sensor for Viper 125-200 cc motorcycles and similar (China, Minsk). The Hall sensor monitors the position of the magneto rotor and sends a signal to the CDI unit, which is used to produce the spark at the right moment.
If the engine suddenly stalls, does not start with a good spark plug or runs intermittently, diagnostics begin by checking the sensor, the coil and the CDI unit. Before replacement, it is worth inspecting the connector and the wires: the cause is often a poor contact.
