Electrical System
The electrical system may have a charging circuit.
The electrical system will have a starting circuit, and
a low amperage circuit. Some of the electrical system
components are used in more than one circuit.
The charging circuit is in operation when the engine
is running. The alternator for charging the battery (if
equipped) makes electricity for the charging circuit.
An internal voltage regulator in the alternator controls
the electrical output in order to keep the battery at a
full charge.
The starting circuit is in operation only when the start
switch is activated.
