建议措施

蓄电池和/或蓄电池电缆

  1. 检查主电源开关、蓄电池接线柱和蓄电池电缆连接是否松动、有无腐蚀。 如果蓄电池电缆被腐蚀,应拆下并清洁蓄电池电缆。 紧固所有松动的连接。

  1. 检查蓄电池。

    1. 向蓄电池充电。 请参考专用说明书, SEHS7633, "Battery Test Procedure"。

    1. 对蓄电池进行负载测试。 请参考专用说明书, SEHS9249, "Use of 4C-4911 Battery Load Tester for 6, 8 and 12 Volt Lead Acid Batteries"。

起动马达电磁阀或起动电路

  1. 测试起动马达电磁阀的工作情况。

  1. 检查与起动马达电磁阀连接的导线。

  1. 在起动马达电磁阀和 ECM 处检查起动互锁电路的工作情况。 如有必要,修理电路。 请参考示意图以了解与起动互锁电路有关的信息。

起动马达或飞轮齿圈

  1. 测试起动马达的工作情况。

  1. 检查起动马达上的小齿轮和飞轮齿圈有无损坏。

变速箱(如果适用)或发动机附件

  1. 确保传动系统运动自如。

  1. 拆下并检查可能会锁住发动机的发动机附件。

    以下列出几例可能会锁住发动机的发动机附件。

    • 由后齿轮组驱动的液压泵

    • 空气压缩机

    • 发动机机油泵

    • 其他由发动机驱动的部件

液压油缸锁

拆下各个单体喷油器,检查气缸内有无液体(液压油缸锁)。

注: 将燃油从缸盖中排出。 拆下单体喷油器时,燃油会从缸盖流入气缸内。

发动机内部故障

拆解发动机。 请参考拆解与组装手册。 检查内部部件有无以下情况:

  • 堵转

  • 部件破损

  • 部件弯曲
