Fuel Level Sender
系统运作描述:
发送器的最准确技术参数，请参阅"电阻器、电磁阀和发送器的技术参数"。 表格在正在维修的机器的电气系统示意图中提供。
测试步骤 1. 检查发送器。
- 从机器线束上断开发送器。
- 测量发送器两个触点之间的电阻。
下列数据是近似的正确电阻：
106-3535 液位发送器组件 和 134-3033 燃油油位发送器
- 空箱 ... 240 至 260 Ω
- 油箱半满 ... 97 至 118 Ω
- 油箱全满 ... 27 至 40 Ω
- 油箱半满 ... 97 至 118 Ω
104-5546 液位发送器组件 、 115-2086 燃油油位发送器 、 121-3174 燃油油位发送器 、 136-1617 燃油油位发送器 、 137-5156 燃油油位发送器 、 150-2995 燃油发送器 和 151-1399 发送器
- 空箱 ... 92 至 98 Ω
- 油箱全满 ... 0 至 3.5 Ω
9X-4942 燃油油位发送器
- 空箱 ... 80 至 85 Ω
- 油箱半满 ... 40 至 43 Ω
- 油箱全满 ... 0 至 2 Ω
- 油箱半满 ... 40 至 43 Ω
- 空箱 ... 240 至 260 Ω
- 在测量电阻时，手动启动发送器。
- 在发送器经过从 0 到全行程的变化时，电阻应随之变化。
预期结果:
电阻测量值在技术参数范围内。
结果:
- 正常 - 燃油油位发送器的电阻正确。停止
- 不正常 - 燃油油位发送器的电阻不正确。
修复: 更换燃油油位发送器。
停止
