It can be tested through a multimeter; If the multimeter is modulated to a resistance range and the obtained data exactly matches the resistance value of the rectifier, then it indicates that the rectifier is good. Rectifiers are used in the AC generator power system to convert the AC power generated by the AC generator into DC power, in order to supply power to electrical equipment and charge batteries; The second is to limit the battery current to flow back to the generator, protecting the generator from being burned out by the reverse current. Silicon diodes have the characteristic of unidirectional conductivity, that is, when a certain voltage is applied to both ends of the silicon diode (the positive pole of the power supply is connected to the positive pole of the diode, and the negative pole of the power supply is connected to the negative pole of the diode), the diode conducts and there is current flowing through it. Conversely, the diode does not conduct and there is no current flowing through it. A rectifier is composed of four diodes, with two diodes connected in series in a clockwise direction and then connected in parallel. Each adjacent corner of the rectifier bridge is a diode. The measurement of the diode can be done using the diode block of a digital multimeter, but this measurement only indicates the good or bad of the diode. For specific data, it needs to be measured using a transistor characteristic graph
