装载机交流发电机充电指示灯常亮，交流发电机不充电，此时将点火开关放置“ON”档，充电指示灯亮，这是正常的，说明充电指示灯自身没有损坏。启动发动机，发现充电指示灯依旧是亮的，正常情况下，它应该是灭的，可能是由于交流发电机不充电，使指示灯继电器常闭导致。 熄火，检查交流发电机，闻到线路被烧焦的味道。拆下交流发电机进行解体，发现内部线路烧坏，更换新的交流发电机。
Shandong loaders alternator charging indicator light, the alternator is not charging, this time placing the ignition switch "ON" file, charging indicator light, which is normal, indicating that the charge indicator itself is not damaged. Start the engine and found that the charge indicator is still lit, under normal circumstances, it should be destroyed, probably due to the alternator is not charging, so that the indicator relay normally closed leads. Flameout,check the alternator, the smell of charred flavor line. Remove the alternator disintegration found burned inside the lines, replacement of the alternator.

装载机电压调节器是利用电阻来改变调压器内部电流，进而改变触点通断电时间，最终完成对交流发电机励磁电流大小的控制。而过热的那条线路就是励磁电路?？蠢词堑缪沟鹘谄髂诓肯呗烦鱿至斯收?，更换新的电压调节器。启动发动机，观察一段时间，故障不再出现。
Shandong loaders voltage regulator resistance to change is the use of internal current regulator, and then change the contact through the off time, the final completion of the alternator excitation current size of the control. And that

line is overheating excitation circuit. Appears to be an internal voltage regulator circuit fails, the replacement of the voltage regulator. Start the engine, observe a period of time, the fault is no longer present.

很多情况下，大家会认为装载机电压调压器是用来改变交流发电机充电电压的，但往往忽略了，它是通过改变交流发电机励磁电路电流大小来实现的，如果能深知这点，故障就比较容易解决了。
In many cases, you will think of Shandong loaders voltage regulator is used to change the alternator charging voltage, but often overlooked, it is by changing the alternator field circuit current size to achieve, if we can know this point of failure is relatively easy to solve.

在遇到电器故障的时候，不一定忙于去拆解，而应该很好利用电路图去分析解决问题，可能会有事半功倍的效果。
In the face of an electrical malfunction, not necessarily busy to disassemble, but should make good use of the circuit diagram to analyze and solve problems that may have a multiplier effect.
