Message Check both with multimeter.

With car off, you should see ~12V at the battery. Ideally a bit higher. If this is true, battery is likely good.

With car running you should see ~14V at battery. If not, alternator may be bad (usually voltage regulator, but still requires replacement of whole unit)
