现很多装有交流发电机的进口汽车都用充电指示灯取代电流表。为控制充电指示灯,一般均在线路上增加一组指示灯继电器,该继电器是利用交流发电机中性点Ⅳ的输出电压,供给线圈电流,产生电磁吸力,控制触点闭合;N无电压输出触点断开,从而得到指示灯暗亮。在汽车运行过程中,指示灯继电器工作频繁,线圈烧毁现象较多,而造成不充电,在无配件 Many imported cars equipped with alternators now replace the ammeter with charging lights. In order to control the charging indicator light, a group of indicator light relays are usually added on the line. The relay uses the output voltage of the neutral point IV of the alternator to supply the coil current and generate the electromagnetic attraction to control the contact closure. N No voltage output contact Point to disconnect, which led to dark light. In the process of running the car, the light relay work frequently, the coil burned more, resulting in no charge, without accessories
