Abstract

PURPOSE:To obtain a simple circuit at low cost for preventing a battery from reverse connection, by providing a relay, not operating when the battery is reversely connected, in a place between the battery and input parts of loads. CONSTITUTION:To a battery 2 through switches of a fixed contact 4 and movable contact 5 in a relay 3, a plurality of loads 6a-6d, for instance, relating to engine controls, torque converter, antiskid devices and the like with use of various semiconductors, are parallelly connected and fed with electric power respectively. Trough said contacts 4 and 5 of the switch are short-circuit connected by electric conduction of flowing a current in an excitation coil 9 of the relay 3, a reverse current inhibiting element diode 8 is interposed to said excitation coil 9. Accordingly, even if a key switch 1 is turned to connect the battery 2 to an IG terminal in a state of reverse connection of said battery 2 to that as shown in the drawing and cause so- called battery reverse connection, the flow of a current is cut out by the diode 8 not to operate the relay 3, thus the loads can be protected.
