Electric power supply system for vehicle
First Claim
1. An electric power supply system for a vehicle, comprising:
- a generator driven by an engine to generate electric power;
a battery charged by the electric power generated by said generator;
a control unit for controlling said engine by electric power supplied from said battery; and
a relay disposed between said battery and said generator and operative to make disconnection or connection between said generator and said battery according to an instruction from said control unit, thereby inhibiting charging or canceling the inhibition of charging, wherein said relay is included in a circuit that can be detachably attached to said control unit, and said control unit is configured so that a connection circuit for connection of a connection terminal to the circuit that includes the relay can be detachably attached in place of the circuit that includes the relay.

Abstract
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.
