故障现象:一辆NJ1041轻型载货汽车,发动机起动由时好时坏而发展到不能起动。故障检查:经测量,打开点火开关点火线圈的电压为12伏,将点火开关转到起动挡时电压却消失,点火开关转离起动挡点火线圈又恢复12伏电压。说明起动时点火线圈低压电路没有电,估计点火开关有问题。但更换点
Symptom: a NJ1041 light truck, the engine start from good times and bad development can not start. Troubleshooting: After measuring, turning on the ignition switch ignition coil voltage is 12 volts, the ignition switch to the starting gear voltage disappears, the ignition switch away from the starting gear ignition coil and restore 12 volts. Ignition coil ignition circuit when there is no electricity, it is estimated ignition switch problems. But change the point
