一辆金龙XMQ 6760NF客车,累计行驶23万km,出现不开空调时,发电机发电量足够使用,仪表盘上的电压表显示发电机的输出电压为26V;打开空调后,发电机发电量明显不足,特别在高速行驶后,电压表显示发电机的输出电压在24V以下,造成蓄电池亏电,起动机无法正常运转的现象。曾因此到其他修理厂检修过,怀疑是发电机有故障,换上一个新的发电机,但使用了近10天又造成蓄电池亏电。
A Jinlong XMQ 6760NF bus, accumulative total travel 230,000 km, appears not open air conditioning, the generator enough power to use the dashboard voltage meter shows the generator output voltage is 26V; open the air conditioning, the generator power is obvious Insufficient, especially at high speed, the voltage meter shows the generator output voltage below 24V, resulting in battery power loss, the starter can not be normal operation of the phenomenon. Have therefore to other repair shop overhaul, suspected generator is faulty, put on a new generator, but the use of nearly 10 days has caused the battery loss of electricity.
