Power circuit for marine engine

摘要

One embodiment of an engine has an electrical system generally comprising a charge circuit and an ignition circuit. A primary power supply circuit connects the charge circuit and the ignition circuit through a non-contact switch circuit. The non-contact switch is adapted to connect the primary power supply circuit to the ignition circuit when the engine is started. A secondary power supply circuit is coupled to at least one electrical component and to the ignition circuit. The secondary power supply circuit has a main switch and a fuse arranged upstream of the main switch. Upon closing the main switch, the engine is started and the primary power supply circuit and the associated non-contact switch are closed. Another embodiment of the engine has an electrical system which adds control of a fuel injector circuit. The fuel injector circuit is in electrical communication with the ignition circuit and a switching circuit which controls the ignition circuit and the fuel injector circuit.
