我单位的一台卡特966D装载机曾出现起动后全车无电，发动机不能起动或起动后加大油厂1就熄火，但不能断电等故障。经检查，油路部分无故障，继电器及电磁阀的性能也良好，初步断定故障是由电气系统线路引起的。其电源。起动及熄火部分电路原理如附图所示。发电机IE常运转时，其 A Carter 966D loader in our unit had appeared after the start of the whole car without electricity, the engine can not start or start to increase the oil plant 1 to turn off, but can not power failure. After inspection, the oil part of the fault-free, the performance of relays and solenoid valves are also good, initially concluded that the fault is caused by the electrical system lines. Its power. Part of the circuit to start and turn off the principle shown in the figure. Generator IE often run, its
