<p>PURPOSE:To surely prevent a motorcycle from being stolen by leaving a semi- conductor switching element in a non-conductive state, which is located between a side stand relay and a circuit open/close switch when a lead wire of an ignition switch is directly coupled, and thereby making it impossible to energize a starter relay. CONSTITUTION:The starter circuit of a motor cycle includes a power supply circuit furnished with a battery 50 and an ignition switch 60, and the power supply circuit is opened/closed so as to be controlled by a side stand interlock circuit 2 which controls electric supply and suspension to a battery type ignition device 80 and a starter relay circuit 61. In this case, even if the lead wire (R, B) of the ignition switch 60 is directly coupled in order to directly couple the power supply circuit to steal the motor cycle, the battery 50 is not connected with a check circuit 10, a capacitor 4 is not thereby charged. This thereby enables energizing starter relay circuit 61 to be checked with a transistor 3 made non-conductive and also with the side stand relay 57 left turned off.</p> |
