Abstract

PURPOSE:To prevent an earth magnetic sensor from being affected by the magnetic field which is produced when each electrical parts is active, by carrying out a wiring process so that the magnetic field produced from the harness of the electrical parts eliminates the magnetic field produced by the electrical parts and applied to an earth magnetic sensor. CONSTITUTION:When an azimuth meter is mounted to a car, a wiring process is carried out so that the magnetic field which is caused by the current flowing to the harness of an electrical parts eliminates the magnetic field which is applied to an earth magnetic sensor via the electrical parts in accordance with the direction of the magnetic field which is applied to the earth magnetic sensor of the azimuth meter and by the magnetic flux which is caused from each electrical parts provided in a car. For instance, the magnetic field H1 caused by the magnetic flux leaked out of an electromagnetic clutch 3 provided right under a bonnet is eliminated by the magnetic field H2 caused at the area of an earth magnetic sensor 2 by a harness 5 connected to an electromagnetic clutch 3 from a battery 4.
