PURPOSE: To inspect the function of an electric load simply and drive the electric load surely and safely. CONSTITUTION: A controller 11, power supplies 20, 20A, and an ignition element 12 to which power is fed from the power supplies 20, 20A are provided in a safety device for vehicle riders. In an ignition circuit, a capacitor 22 and a series oscillation circuit comprised of a coil 21 are connected to the ignition element. Whether the ignition circuit is working normally can be inspected easily by supplying alternating current to the ignition circuit through the power supply 20 and detecting the impedance of the ignition circuit. |
