How can you tell if the generator is charging properly?

The correct answer, which indicates that the generator is charging properly, is associated with the red indicator light. When the red light goes off, it signifies that the charging system is functioning correctly; this light generally acts as a warning signal for any charging issues. Its deactivation indicates that the generator is successfully supplying power to the battery and that the battery is being charged as intended.

Other factors like the engine temperature or changes in sound may not directly correlate with the charging status of the generator. While an increase in battery level indicates successful charging, reliance on a battery gauge can sometimes be misleading due to other potential factors affecting battery health. Focusing on the red indicator light is the most straightforward and reliable method to ascertain the generator's charging status.
