裝載機交流發電機充電指示燈常亮，交流發電機不充電，此時將點火開關放置“ON”檔，充電指示燈亮，這是正常的，說明充電指示燈自身沒有損壞。啟動發動機，發現充電指示燈依舊是亮的，正常情況下，它應該是滅的，可能是由于交流發電機不充電，使指示燈繼電器常閉導致。 熄火，檢查交流發電機，聞到線路被燒焦的味道。拆下交流發電機進行解體，發現內部線路燒壞，更換新的交流發電機。
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.

裝載機電壓調節器是利用電阻來改變調壓器內部電流，進而改變觸點通斷電時間，最終完成對交流發電機勵磁電流大小的控制。而過熱的那條線路就是勵磁電路。看來是電壓調節器內部線路出現了故障，更換新的電壓調節器。啟動發動機，觀察一段時間，故障不再出現。
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.

很多情況下，大家會認為裝載機電壓調壓器是用來改變交流發電機充電電壓的，但往往忽略了，它是通過改變交流發電機勵磁電路電流大小來實現的，如果能深知這點，故障就比較容易解決了。
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.

在遇到電器故障的時候，不一定忙于去拆解，而應該很好利用電路圖去分析解決問題，可能會有事半功倍的效果。
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.
