What are the signs of a bad Honda alternator?
Dim headlights Dimming headlights are one of the most common signs of a bad alternator in the Honda CR-V. Dim headlights indicate that the alternator can’t keep up with the energy request for the lights. As your CR-V begins to eat through the voltage stored in the battery, the headlights will begin to fade.

The alternator’s job in your CR-V 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. It is turned by a serpentine belt.

If the battery light is on when the voltage is above 13v then something is still wrong with the alternator as the switch for the light is in the alternator.

Kill the radio, daytime running lights, air conditioning, heated seats, EVERYTHING. That will allow all of the limited voltage in the battery to go to the ignition system. If your CR-V’s alternator starts to have bearings that fail, it’ll begin to make some very obnoxious noises.
