1故障现象:关断点火开关起动档位置时,起动机继续运转。2原因:电磁卉关吸拉线圈部分短路(如图1A．B两点所示)。3分析:电磁开关在开始工作时,只要按下起动按钮或打开点火开关起动档位置时,电磁开关吸拉线圈与保位线圈同时得电(两线圈并联),由于电流方向一致,磁力加强,吸动活动铁芯,主电路接通,起动机工作。此时吸拉线圈被短路,活动铁芯只靠保位线圈的磁力保
1 Symptom: turn off the ignition switch starting position, the starter continues to run. 2 reasons: electromagnetic switch pull pull coil part of the short circuit (as shown in Figure 1A.B two points). 3 Analysis: When the electromagnetic switch starts to work, just press the start button or open the start position of the ignition switch, the electromagnetic switch to pull the coil and hold the coil at the same time get the power (two coils in parallel), due to the same current direction, enhanced magnetic force, Suction activity core, the main circuit connected to the starter work. At this point suction coil is short-circuited, the activity of the core alone to protect the magnetic coil security coil
