PURPOSE:To eliminate a restriction on wiring for a car body by wiring both an input harness and an output harness of a battery closely to each other and in parallel, to utilize an offsetting phenomenon of magnetic field caused by large current, and preventing induced voltage in an electromagnetic pickup PU, leading to an erroneous operation, by means of said offsetting phenomenon. CONSTITUTION:Input and output harnesses 5a, 5b of a battery, through which a large current or a current having a large rate of change in current with time flows, are wired mutually closely and in parallel, to offset a magnetic field generated by said large current or current having a large rate of change in current with time. Thereby, it is possible to prevent induced voltage from generating in an electromagnetic pickup means which generates an electric output corresponding to the rotation of an engine 2. And, it is also possible to wire a harness through which a current for a starter, head light, etc. whose quantity varies greatly with time flows, closely to the electromagnetic pickup, eliminating restrictions on wiring for a car body, and improving reliability. |
