Grounding Practices

Usage:

3512B 4AW
为获得发动机的最佳性能和可靠性有必要使发动机电气系统接地正确。 接地不正确将会造成电路不受控制。 电路路径将会不可靠。

不受控制的电路会对主轴瓦、主轴颈表面和铝质部件造成损坏。

不受控制的电路路径可能会引起电气噪声。 该噪声可能会降低发动机的性能。

必须使用直接路径到蓄电池以确保发动机电气系统工作正常。

接地线和接地带应在发动机接地螺柱处汇合相接。 接地螺柱应专用于接地用途。 每 250 小时,检查所有发动机接地点。 所有接地装置必须紧固和无腐蚀现象。

发动机有几个电子输入部件。 这些部件需要工作电压。

与以往的许多电子系统不同,本发动机可耐受常见的外部电子噪声源。 但是,电动机械式警报器可能会引起电子系统供电中断。 本发动机的电子控制模块 (ECM) 经由两路电源供电。 一路电源直接来自蓄电池,中间经由一个断路器。 另一路电源经由钥匙开关和另一个断路器而来。 使用主电源的切断开关来关断电源。
