我公司最近到的一批NK649型大客车,装的是JF13型交流发电机,调节器仍使用原配的直流发电机的小三联调节器。由于接线方法不对(充电系统工作正常),产生发动机在关断点火开关时(即使怠速时温度60℃)仍不熄火的故障。
A number of NK649 coaches recently arrived by our company are fitted with JF13 alternators and the regulators still use the small triple regulators of the original DC generators. Due to wrong connection method (the charging system is working properly), a malfunction that the engine does not turn off even when the ignition switch is turned off (the temperature is 60 ° C at idle) is generated.
