  • Voltage adjusting circuit, and motorcycle including voltage adjusting circuit
    Patent number: 7764052
    Abstract: A voltage adjusting circuit prevents damage to an electrical component having no over-voltage protecting circuit when a battery is removed. An LED tail light is connected to an over-voltage protecting circuit of a CDI unit. Electric power is supplied from a power supply control section to the CDI unit and is also supplied to the LED tail light through the over-voltage protecting circuit. Thereby, the over-voltage protecting circuit of the CDI unit protects the LED tail light from an over-voltage condition.
