在检修启动系故障时,常遇蓄电池存电较足,启动机良好,而装车使用时,启动机却转速低、转矩小,无法将车辆启动或迅速启动。尤其是冷车或冬季初启动时,此类故障更为明显。根据启动机电源由蓄电池正极→导线→开关→启动机→搭铁→蓄电池负极构成回路这一电路基本原理 In the repair start-up failure, often meet the battery storage enough to start a good machine, and loading when used, the starter speed is low, the torque is small, the vehicle can not be started or quickly started. Especially in cold or winter start-up, such failures are even more noticeable. According to the starter power from the battery positive → wire → switch → starter → ground → battery negative constitute the circuit of the basic principles of this circuit
