If the heatercircuit is working, it heats the sensing blub, thus changing the resistance of the bulb.
如果加热电路工作,它加热温度传感头,从而改变传感头的阻值。

The heatercircuit power wire is supplied directly from the ignition circuit or a relay and the heatercircuit ground is connected directly to the ground plane.
加热器电路接地线直接连接到地面,加热器电路电源线也直接从点火电路或继电器盒处提供。
