摘　　要：车辆蓄电池到起动机主电路电缆(30端子连接线)的总电阻应小于2mΩ,而一般强制啮合起动机电磁开关总电流小于60A,蓄电池到电磁开关连线(50端子连接线)总电阻取Rs≤50mΩ,即可保证工作时线路电压降小于额定电压的25%,起动系统可正常工作。The total resistance of the wire connecting the battery terminal B＋ and the starter terminal 30 should be less than 2 mΩ, while the solenoid current of normal starter less than 60 A, so the resistance of the wire connecting the battery terminal B＋ and the solenoid terminal 50 should be less than 50 mΩ, thus it can ensure the voltage drop less than 25% of the rated voltage when the starter works normally.
