某东风EQ140汽车,在保修后运行一个月内,连续损坏了三只蓄电池。在此期间先后曾更换了发电机和调节器仍然如故;刚换上去的新电池用不了几天无法起动发动机。经维修人员对车辆进行检查,最后在检查调节器时才发现:是其“火线”与“磁场”上的两线接反。根据发电机及调节器工作原理和通过计算调节器铁芯线圈的电流可知:发电机调节器接线正常时其电流约0.6A即起到节约作用;当调节器(误接)在非正常情况时,其电流约0.45A左右,也就是说在非正常时电压值高达18.5V才能使触点断开。因此,蓄电池电解液出
A Dongfeng EQ140 car, running within one month after the warranty, continuous damage to three batteries. During this period has replaced the alternator and the regulator still the same; just replaced the new battery can not start the engine within a few days. The maintenance staff to check the vehicle, the last check when the regulator was found: is its “FireWire” and “magnetic field” on the two-line connection. According to the working principle of the generator and the regulator and by calculating the current of the regulator iron core coil, it can be seen that the current of the generator regulator is about 0.6A when the wiring is normal; when the regulator (misconnection) is under abnormal conditions , The current is about 0.45A or so, that is not normal in the voltage up to 18.5V to make the contact open. Therefore, the battery electrolyte out
