Honda CB400 and CB450 Wiring Diagram and Schematics

Honda CB400 and CB450 Wiring Diagram and Electrical Schematics The following electrical wiring diagram and schematics applies for Honda CB400 and CB450 motorcycle series 1978 – 1987 models. The electrical system includes the following systems: Charging System, Ignition System, Lighting System, Turn Signals, Horn, and Wiring Diagram. The charging system consists of battery, alternator and voltage regulator/rectifier. The alternator generates an alternating current (AC) which the rectifier converts to direct current (DC). The regulator maintains the voltage to the battery and load (lights, ignition, etc) at a constant voltage regardless of variation in engine speed and load.

An alternator is a form of electrical generator in which a magnetized field called rotor revolves within a set of stationary coils called a stator. As the rotor revolves, alternating current is induced in a stator. The current is then rectified and used to operate electrical accessories on the motorcycle.
