近年来汽车上用交流发电机代替了直流发电机.由于交流发电机中有电子元件(当与晶体调节器匹配时则有更多电子元件),故对其故障的检查与排除与直流发电机有着很大的区别,这点必须予以注意.否则,弄不好就会造成新的故障. In recent years, AC alternators have been used to replace DC generators in automobiles, because of the presence of electronic components in the alternator (there are more electronic components when matched with the crystal conditioners), the inspection and troubleshooting of the alternator and DC generator There must be a big difference, which must be paid attention to, otherwise a new failure may be caused if things go wrong.
