  1. 通过接通灯或其他负载大约 5 分钟,将蓄电池电压消耗到低于 12.4 V。 起动机器。

  2. 检查交流发电机电缆的安培数。 这将根据驾驶室中接通的功能而异。 安培数应大约为 20-40 安培。

    注: 随着蓄电池电量增加,交流发电机电流输出将减少。

  3. 检查蓄电池正极接线柱上的电压。 操作 10 分钟后,电压应为 14 V ± 0.5 V。 如果符合技术规格,则交流发电机状况良好。 如果不在 14 V ± 0.5 V 以内,则转至下一步骤,以便在更换交流发电机之前,对整个电路进行故障诊断与排除。

  4. 检查交流发电机皮带的状况,并检查皮带张力是否符合技术规格。 请参阅机器操作和保养手册,了解正确的皮带张力。 进行任何必要的修理,然后重复步骤 3。

  5. 检查交流发电机传动皮带轮和交流发电机轴承的状况。 进行任何必要的修理,然后重复步骤 3。

  6. 检查蓄电池电缆、发动机接地和导线。 根据需要清洁和/或用钢丝刷清理接头。 进行任何必要的修理,然后重复步骤 3。

  7. 在点火开关处于接通位置时,通过用万用表的正极引线接触导线端子,并用负极引线接触任何机架接地,确认交流发电机上的信号线具有 12 V 电压。 如果不具有大约 12 V 电压,则对从保险丝盒到交流发电机的导线进行故障诊断与排除。 进行任何必要的修理,然后重复步骤 3。

    注:交流发电机信号线如下:

    • 滑移式装载机、多地形装载机和紧凑型履带式装载机是 123-WH

    • 紧凑型轮式装载机是 111-YL

    • 小型液压挖掘机是 123-WH
