Patent attributes
To enable a circuit configuration to be easily changed over depending on whether a recoil starter is present or absent. A battery charged by a generator driven by an engine, a charging circuit for charging the battery by the generator, and a drive electric power supply circuit for supplying engine drive system loads with electric power generated by the generator, are provided. In a system having a recoil starter, a contact configuration is adopted in which, when an ignition switch is changed over to a recoil start position, the charging circuit is disconnected and the drive electric power supply circuit is connected. The disconnection of the charging circuit may be conducted by use of a charging inhibition relay. The charging inhibition relay is formed as a sub harness, and, in a system not using the recoil starter, the sub harness is replaced by a sub harness in which the charging inhibition relay is not mounted.
