Beschreibung
Zusammenfassung:	本发明所述的汽车电负荷监视装置备有至少两个电负荷和控制负荷中电流的开关装置，采用动态退耦电路，靠检测电负荷的电位实行监视，与先有技术相比，具有系统简单、省元件、廉价等优点。 A device for monitoring operational condition of electrical consumers in a motor vehicle, particularly of heater plugs of a diesel engine, includes inductances connected in series between respective heater plugs and their d.c. supply. Alternating or pulsating current is supplied to a connection point of the inductances with the d.c. supply, and potentials across the inductances and the heater plugs are simultaneously evaluated to indicate a defective heater plug.
