Re: Alternators
A nice gauge to have in your car is a voltmeter. I have a voltmeter and an ammeter and an alternator. I watch both meters. After I start the car the current is 15 amps, but once the voltage gets to my charged battery voltage the current drops to zero.
Bob in the post above has a valid concern. The alternator is probably OK but there is something else going on. Maybe a loose connection somewhere, the battery is starting to fail, or a current drain somewhere. You might check everything with your multimeter and take the battery to an auto parts store to have it load tested.
