Build circuits with batteries, resistors, light bulbs, and switches. Determine if everyday objects are conductors or insulators, and take measurements with an ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a lifelike view.. GENERAL THEORY. The electrical system of a motorcycle can be thought of in very simple terms. It consists of three parts: an alternator/generator that is designed to provide electricity to run the motorcycle and charge the battery, a rectifier or rectifier pack that is designed to keep the power coming from the alternator/generator from over-charging the battery and from sending too much power.
