  • Patent number: 9488148
    Abstract: An engine starting device is basically provided with a resistor, a bypass circuit and a switch. The resistor is configured to be disposed in series between a starter motor and a battery. The bypass circuit is disposed in parallel with respect to the resistor. The switch is configured to selectively open and close the bypass circuit, the switch opening the bypass circuit in response to commencement of engine startup, and closing the bypass circuit in response to the battery voltage approaches a maximum value during engine startup.
