start the car, let it run for about 10 to 20 minutes then disconect the batery, the car should stay on (for a few minutes ofcourse) if it dies right away then the alternator is bad Other posts on other sites say this is NOT to be done or serious damage can occur. Do it at your peril.
What else can I help you with?
What causes a auto alternator to go bad or short out?
the alternator belt could be slipping so check the belt, the wiring at the alternator could be faulty do a check with a multimeter. open the alternator and check the diodes .apply battery power and see if the rotor still spins inside the stator see current output
What cause batterie ligh to stay on after changing batterie and alternator?
Check volatages everywhere, there could be a short somewhere. Also, check the tension on the belt that drives your alternator. That belt might be slipping due to a faulty tensioner and not spinning the alternator fast enough.

Can a faulty alternator drain a new battery?
It can, though it is unlikely -- the alternator and the voltage regulator would both have to be faulty. A faulty alternator will not charge a battery, though, so it may seem normal until the charge put into the battery at the store runs out.

A faulty alternator, a faulty belt tensioner.
What would cause a whining noise while accelerating?
Whining noises often come from the alternator or the steering pump. Check the power steering fluid in the pump (there is a dipstick on the pump), and have an AVR test done on the alternator. If the alternator is faulty, you are probably having battery problems as well. If the steering pump is low on fluid or is faulty, you probably are experiencing jerky steering from time to time.
What could be wrong if my battery light comes on?

A quick test I've always used is to start the car. Remove the neutral cable from the battery. If the car still runs your alternator is fine.

Yep, check those links. Or maybe someone sold you a faulty alternator. Did they check it before you bought it???
