He found after another inspection that a protectingdiode(its circuit inside the fuse case) on the air conditioner clutch in between foot No.87 of the air conditioner clutch relay socket and foot No. C11 of the fuse case harness pin was broken down.
This feature eliminates the Schottky diode that is used in some systems for protecting the load from reversed output voltage events.
此功能消除了肖特基二极管，在某些系统用于保护从反向输出电压事件负荷。
Here, we present a method of the semiconductor diode shielding the negative voltage that starvation produces, by inhibiting the negative voltage to achieve the function of protecting the fuel cell.
