A current flowing through the automotive battery and the battery voltage are measured by the battery current measuring means and the battery voltage measuring means. The battery is connected to a plurality of wiring harnesses which in turn connect to a plurality of loads. Data on normal resistance values between the battery and the wiring harnesses as produced by each of the loads being activated are stored and held in the load current data holding means. When the resistance value comparison means determines that the resistance value between the battery and the wiring harnesses calculated by the resistance value calculating means does not agree with the data of normal resistance values between the battery and the wiring harnesses held by the load resistance data holding means and produced by each of the loads being activated, it is decided that abnormal currents are flowing through the wiring harnesses.
