PURPOSE:To avoid generation of a fire by a spark in a short trouble part due to short-circuiting by interposing a fuse in a rectifier side of a capacitor in the first circuit. CONSTITUTION:A fuse 1 is interposed in the side of a smoothing circuit 27 of a capacitor 25 in the first circuit 22. Now in the case of generating a short trouble by short-circuiting both ends of a lamp 23 in the first circuit 22 due to any cause, a short-circuit current from an alternator 20 is allowed to flow in the first circuit 22, and the fuse 1 is blown by this short-circuit current. While also in the case of generating an internal short trouble in the capacitor 25, the fuse 1 is blown similarly by the short-circuit current from the alternator 20. In this way, generation of a fire due to repeating a spark in a short trouble part can be prevented, while a degree of break of the capacitor 25 can be suppressed. |
