Figure 25 Identification of the components utilized in a typical automotive charging system
Typical Automotive Charging System
| BATTERY: Power source when engine off. Supplies electrical current: - when ignition switch is in ACC or ON position; or - to start the car. |
FUSE LINK: Protects alternator wiring and diodes from damage if: - a short-to-ground occurs; - battery polarity is reversed. |
ALTERNATOR: Power source when engine
running. Converts mechanical energy Into electrical energy to: - charge the battery; or - supply current to car's electrical system |
 | ||
| VOLTAGE REGULATOR: Controls alternator voltage output to prevent the charging system from: - overcharging; or - undercharging. |
WIRING HARNESSES: - connect charging system components. |
AMMETER/ INDICATOR LIGHT: Visually indicates charging system problem by: - light glowing (indicator light); or - registering overcharge or undercharge (ammeter). |
