The altersnators are widely used in automobiles. When using them, you should pay attention to the following points:
① Frequently clean the scale and dust on the surface of the generator, and keep it clean and well ventilated.
② Frequently check the tightening conditions of the generator-related fasteners and tighten the screws in time.
③The tension of the transmission belt must be appropriate. If it is too loose, it will slip easily and result in insufficient power production; if it is too tight, it will easily damage the belt and generator bearings.
④When installing the battery, be careful not to install it incorrectly. Usually, install the positive wire first and not the ground wire, otherwise the diode will burn out easily.
⑤ When using an integrated circuit regulator, the ignition switch should be turned off immediately when the engine is not running.
⑥ It is never allowed to use the “scraping” method to test whether to produce electricity.
⑦ When the generator fails to generate electricity, it must be eliminated in time, otherwise it will cause more serious failure.
