Charge (Battery) Telltale Indicator Lamp

The charge (battery) telltale indicator lamp is pulled to ground by the voltage regulator, located internal to the generator. When the lamp is pulled to ground, ignition voltage flows through the lamp, allowing it to come On. This indicates to the operator of the vehicle that there is a possible problem in the charging Circuit.

The charge (battery) telltale indicator lamp will turn On, for approximately 1 to 2 seconds, during engine start-up until the voltage regulator senses voltage Output by the generator for a bulb check.
