What does an alternator do on a Honda Odyssey?
The alternator’s job in your Odyssey is to provide electricity as it is running. The battery stores enough voltage to be able to start the engine without the assistance of an alternator.
How many volts does a Honda alternator need?

What are the symptoms of a bad Honda alternator?
Here are the most common symptoms of a bad alternator in a Honda Odyssey: The battery light is designed to tell you that there is not enough voltage to properly charge the battery, or that the battery itself is not holding the proper voltage.
