（1）故障診斷接到該車(chē)后，將點(diǎn)火開(kāi)關(guān)放置“ON”檔，充電指示燈亮，這
是正常的，說(shuō)明充電指示燈自身沒(méi)有損壞。
(1) Upon receipt of the car fault diagnosis, placing the ignition switch "ON" file, charging indicator light, which
It is normal, indicating that the charge indicator itself is not damaged.
（2）啟動(dòng)發(fā)動(dòng)機(jī)，發(fā)現(xiàn)充電指示燈依舊是亮的，正常情況下，它應(yīng)該是滅
的。于是，懷疑可能是由于交流發(fā)電機(jī)不充電，使指示燈繼電器常閉導(dǎo)致。 
(2) Start the engine and found that the charging indicator is still lit, under normal circumstances, it should be destroyed
The. Thus, the suspect may be due to the alternator is not charging, so that the indicator relay normally closed lead.
（3）熄火，檢查交流發(fā)電機(jī)，聞到線(xiàn)路被燒焦的味道。拆下交流發(fā)電機(jī)進(jìn)
行解體，發(fā)現(xiàn)內(nèi)部線(xiàn)路燒壞，更換新的交流發(fā)電機(jī)。
(3) turn off, check the alternator, the smell of charred flavor line. Remove the alternator into
OK disintegration found burned inside wiring, replacement of the alternator.
（4）再次啟動(dòng)后，充電指示燈沒(méi)有亮，認(rèn)為故障解決。但沒(méi)過(guò)一會(huì)，又聞到線(xiàn)路被燒焦的異味，并且發(fā)現(xiàn)交流發(fā)電機(jī)外接線(xiàn)路異常熱，立刻熄火。難道還有其他故障？
(4) starts again, the charging indicator does not light, consider troubleshooting. But not after a while, they smelled the odor of charred lines, and found that the alternator circuit abnormal external heat, immediately turn off. Is there another failure?
（5）線(xiàn)路過(guò)熱，一般是由于電流過(guò)大導(dǎo)致，而電流過(guò)大又可能是線(xiàn)路被短路或負(fù)載減少導(dǎo)致。
(5) Line overheating, generally due to the current is too large, and the current is too large and may be short or reducing the load line is lead. 
（6）結(jié)合交流發(fā)電機(jī)的工作電路：蓄電池負(fù)極搭鐵→蓄電池→點(diǎn)火開(kāi)關(guān)→保險(xiǎn)絲→電壓調(diào)節(jié)器→交流發(fā)電機(jī)→搭鐵回路，可以看出，很有可能是由于電壓調(diào)節(jié)器或交流發(fā)電機(jī)被短路導(dǎo)致。而充電指示燈再次啟動(dòng)后會(huì)亮，說(shuō)明交流發(fā)電機(jī)是可以正常工作的，不可能被短路。
(6) combined alternator operating circuit: Ground the negative battery ignition switch → → → Battery voltage regulator fuse → → → Ground alternator circuit, it can be seen, most likely due to the voltage regulator or AC power machine is shorted lead. And after the charge indicator will light starts again, indicating that the alternator is working properly, and can not be short-circuited.
（7）最后考慮只有電壓調(diào)節(jié)器被短路才可能導(dǎo)致線(xiàn)路過(guò)熱。于是，使用萬(wàn)用表“電路通斷”檔檢測(cè)電壓調(diào)節(jié)器，發(fā)現(xiàn)電壓調(diào)節(jié)器并沒(méi)有被短路。這就奇怪了難道還有其他原因？
(7) Finally, consider only the voltage regulator circuit is shorted it may cause overheating. Then, using a multimeter, "Continuity" position detection voltage regulator, voltage regulator found that has not been short-circuited. This is strange Is there another reason?
（8）既然不是短路導(dǎo)致，那就只有負(fù)載減少導(dǎo)致電流過(guò)大。交流發(fā)電機(jī)是新?lián)Q的，應(yīng)該沒(méi)問(wèn)題。那就只有電壓調(diào)節(jié)器了。
(8) Since it is not a short circuit cause, it is only due to reduced load current is too large. Alternator is new for, it should be no problem. It is only the voltage regulator.
