This circuit X is composed of a relay R and a diode D, and when the ignition interlocking switch S is turned on, the relay contact Ra is closed by the excitation of the relay coil Rb to connect the battery B to each electric component A. On the other hand, in the case of reverse connection, the interlock switch S
Even when is turned on, the relay coil Rb is not energized by the diode D, the relay contact Ra is maintained in the open state, and the reverse voltage (current in the reverse polarity direction) from the battery B is not applied to each electrical component A. .
