开路是导致电路中没有电流的故障根源。 开路可能是由电路内导线断开导致。 开路最经常是由电路中使用的电气接头之一中存在连接不良或连接故障导致。

以下步骤是一种检查电路中有无开路或不良连接的方法。

测试有无断路。

  1. 确定可疑电路中的接头和导线编号。 使用机器的电气系统示意图检查电路。

  2. 将钥匙起动开关和断路开关转到断开位置。

  3. 从配线线束上断开部件和 ECM。

  4. 在一个断开的线束连接上,将一根跨接导线连在可疑导线的触点与机架接地之间。

  5. 在其他机器线束接头上,使用万用表表笔测量可疑导线的触点与机架接地之间的电阻。

    预期结果:电阻小于 5 欧姆。

    确定 - 电阻小于 5 欧姆。 线束电路正常。

    停止。

    异常 - 电阻大于 5000 欧姆。 机器线束中存在断路。

    修理:修理或更换机器线束。

    停止。
