CHARGING SYSTEM

Print

When the charging system is operating normally, the warning lamp will come on when the ignition switch is turned on and will go out when the engine starts. If the lamp operates abnormally, or if an undercharged or overcharged battery condition occurs, the following procedure may be used to diagnose the charging system. Remember that an undercharged battery is often caused by accessories being left on overnight, or by a rear compartment or instrument panel compartment lamp that stays on.
