MasterI can give you some of the needed inspections for this, but there are several. First, when you turn on your key with out starting your car, you need to see the Battery Light? This completes the Charging Circuit, it should go off when you start the car, this means that the Alternator has turned off the Battery Light.
You need to see if the Alternator is putting out least 14 volts to the large Battery Cable that is attached to the B+ terminal of the Alternator when the car is running.here is a link to an online repair manual site, that will have more instructions on how to inspect your Charging System.

RookieI have the proper voltage on all three wires to the alternator. When we start the car it just drains the battery and the alternator has no output.

Visitor, November 09, 2010, 09:02ReplyMy car was doing the same thing. Except my alternator belt broke, and my air bag light came on, my horn wouldnt work, and radio wouldnt work. I had that replaced, and my car still wouldnt work! At that time I had a my alternator rebuilt once, and had bought about 3 batteries(alternator kept draining battery) , then a dianostic, and the mechanic told me that a computer was not working in my car, which cause my alternator not to get any juice! Instead of paying bigg bucks, i had bought a kit with a special chip in it, and put in the alternator to bypass the computer which only costed $30!!! We wasnt sure if the chip was going to work, but ive tried it out, and its been working fine since June!

Rookieok well first, mr. dandd is wrong. when you turn the key on and the battery light (along with all the other lights) come on, it is the computer doing a light check to check that all the lights are working. And if the alternator is working correctly it will charge at no more than 14 volts. If it is charging any higher it is over charging.

Visitor, July 15, 2010, 18:47I have the proper voltage on all three wires to the alternator. When we start the car it just drains the battery and the alternator has no output. I am on the fourth alternator. The first one worked for about 80 miles and quit. The rest for about 10 seconds each. I know how to check voltage and what it should be. Need a epiphany, not generic info.

lcdeni, July 26, 2010, 05:32ReplyRookieMake sure it is the right alternator. The guys at NAPA were giving me an alternator for a 1997 instead of a 1998 and they won't interchange. Also the Meter fuse in the fuse box inside of the car (Yes, they put one there and under the hood) was blown and this is what triggers the alternator to charge.
