最近,我单位一辆北京212型汽车。偶尔发生仃车后关闭点火开关,发动机不能熄火现象。根据故障现象诊断为点火开关内部短路造成,便换用了新的点火开关,经起动试验后故障并没有排除,但同时证明故障不在点火开关。后经进一步检查,当查到点火线圈附加电阻与起动机电磁开关连线时,发现附加电阻接线柱有火。 Recently, I unit a Beijing 212 car. Occasionally turn off the car after the ignition switch, the engine can not stall the phenomenon. According to the fault phenomenon diagnosed as the ignition switch internal short circuit, it replaced with a new ignition switch, after the start of the test failure has not ruled out, but at the same time prove that the fault is not the ignition switch. After further examination, when found ignition coil additional resistance and starter electromagnetic switch connection, found that additional resistance terminal fire.
