PURPOSE:To hinder current feed to an ignition system circuit due to irregular severance or shortcircuiting of a wiring by fixing one end of a dummy wire to near a main switch with no regard electrically, and connecting the other end of the dummy wire electrically to a battery pole situated on the opposite side to a fuse. CONSTITUTION:An ignition system circuit 1 is connected with a fuse 5 and a battery 6 through wirings 3, 4 connected with one end of a coupler 2. A main switch 9a is connected with the other end of the coupler 2 through wirings 7, 8. In this arrangement, one-side ends of a pair of dummy wires 10, 11 and another pair 12, 13 are connected with the two ends of the coupler 2. The other ends of these dummy wires 10, 11 are fixed with no regard electrically near the main switch 9a, while the other ends of the ones 12, 13 are grounded to the car body and connected to the battery 6 electrically. Thereby the wirings 7, 8 are cut from the dummy wires 10, 11, and in the even of their shortcircuiting, the fuse 5 is blown. |
