驾驶了几年普通桑塔纳乘用车的朋友都会有一种感觉,夜间行车时其前照灯(俗称大灯)灯光不足以照亮前方路面,会车时尤为明显,给驾驶带来安全隐患,驾驶员眼睛也易疲劳。为解决这一问题,很多人采取更换新的灯具或大功率灯泡等方法,而效果往往不明显。显而易见,大灯的反射镜反光面的老化等并不是该车型产生上述现象最根本的症结所在。进一步从大灯的电路组成方面分析:普通桑塔纳乘用车大灯电路经电源→中央电器→灯光总开关→大灯变光开关→中央电器熔丝→左线束(通过发动机舱)→大灯灯泡→搭铁构成回路。在整条线路构成中有12个断开点,用接插件作连接。在日常维护过程中,这些插接件都不可避免地被分开或接插,
Driving a few years ordinary Santana passenger car will have a feeling of friends, driving at night when its headlights (commonly known as headlamps) lighting is not enough to illuminate the road ahead, will be particularly evident when the car, driving a safety hazard, driving Eyes are also easy to fatigue. To solve this problem, many people take the replacement of new lamps or high-power light bulbs and other methods, and the effect is often not obvious. Obviously, the aging of the reflective surface of the reflector of the headlight is not the crux of the phenomenon that occurs with the model. Further analysis of the circuit from the headlights: ordinary Santana passenger car headlight circuit by the power → central electrical → light switch → headlight dimming switch → central electrical fuse → left wiring harness (through the engine compartment) → headlight bulbs → Ground constitutes a loop. There are 12 disconnect points throughout the line configuration, with connectors for connection. In routine maintenance, these connectors are inevitably separated or patch,
