General Information
作为参考,本手册中的每个电路测试中都包括每个发动机子系统的简化示意图。 请参考电气系统示意图,以便了解您的应用的整个电气系统的准确电路图。
故障诊断与排除期间,在更换任何部件之前应先检查所有线束连接。 如果这些连接不清洁、不牢固,则可能会导致连续性电气故障或间歇性电气故障。 检查并确认已将导线完全推入接头中。 在进行其它测试之前,确保所有连接牢固。
一个电子部件出现故障可能会引起其他部件出现故障。 更换一个部件之前一定要尝试排除电气系统故障的起因。 如果刺穿了导线绝缘层,则应修理损坏部位。 使用 8T-0065 硅胶密封剂 密封损坏的导线。 用两层 1P-0810 绝缘胶带 封住密封胶。
注: 本手册涉及 CG137-8 和 CG137-12 发动机。 与空燃比控制和催化剂有关的材料仅适用于 CG137-12 发动机。 这些系统由 Caterpillar 提供,仅适用于 CG137-12。 CG137-8 系统由客户提供。
