Alternator output fuse or fusible link under the hood, I can't believe the people that don't state make, model, year and engine size before posting a question.

Can a car start with a bad alternator?
Yes it can as long as the battery is charged . The purpose of the alternator is to put the power used back into the battery.

Your 1993 Pontiac transport will not charge battery an battery good and battery hand reading nothing with engine running an already had alternator check an replace pcm but there is still no charge?
Does the Alternator have a power supply back from the battery to excite the alternator? I had the same problem and despite trying several alternators found that a fuse had blown on the circuit bring power back from the battery. Or the bushes in the alternator could be worn out or the diode pack could be shot. Put a volt meter onto the small wire on the alternator and across to the vehicle body you should have battery voltage on this terminal.
What does the wire do that goes from the positive battery terminal to the back of aternater?
This is the main output from the alternator. It charges the battery and maintains power to the rest of the car's circuitry.
Where do the wires go on a Vauxhall alternator?
from the back of the alternator to the dash to the battery
Why is my VW Passat's battery being drained?
It's most probably the alternator. It's not putting any charge back in the battery. Can also be a dead cell in the battery or something is on pulling power from the battery.
1998 GP GT has problems starting I hear a click and the power dies. Sometimes the power comes back when i turn the key but when I turn it to start it does the same. Cleaned the leads but does no help?
You have a bad battery, alternator, or starter solenoid. Load test the battery first, then the alternator.
Battery light was on and checked to see if it was the alternator and the alternator was bad have not fixed the alternator and now the battery light has not come back on what could be the problem?
There is no problem...the problem was the alternator. You have fixed the problem.
How do you replace the alternator on a 1999 Pontiac Sunfire 2.2L?
Disconnect the negative cable on the battery. Loosen the tensioner for the accessory belt for the alternator and remove the belt. Remove the two long bolts that are holding the alternator in the bracket. Do not let the alternator fall and tear the wires. Support it as it comes loose so you can reach the wires. Remove the main battery wire off of the single power connection on the back of the alternator. Remove the electrical connector that is the field connection from the back of the alternator and put it out of the way. Install the new alternator with the bottom bolt first. Rotate the alternator upward and insert the top bolt through the bracket and alternator and then tighten top and bottom bolts. Install the main power wire to the back of the alternator followed by the field wiring harness connector. Install the accessory belt and tighten. Check the battery before starting and make sure it is not to low. If it is, charge the battery before starting so as not to damage the new alternator. An alternator is not designed to run at full capability for extended periods. This will overheat the new alternator, possibly causing damage. If the car does not have a voltmeter gauge then it is a good idea to use a voltmeter and check across the battery with the car running. There should be a charge of 14.5 going into the battery.

What would drain your battery after replacing alternator and battery?
Is it possible that you hooked up some of the wires on the alternator reversed. An alternator has to be "exited" meaning that you need to put a little power in to it to get alot of power back out of it. If one of the wires you hooked to it was a "constant hot" (on all the time) and not a "keyed hot" (on with the key) the alternator itself can drain the battery. If you are sure this could not be it you're going to need to put a multimeter on the battery and pull and replace one fuse at a time until you find the drain. (It will stop drawing when you pull the right fuse) Be careful because the clock/radio is a constant drain but a very small. Save that fuse for the very last.
As the car battery is charging should the meter move back and forth?
Not really. It should only move a little bit. If the alternator is not producing full power at idle, you may have a bad alternator.
Why do your dash lights flicker and your engine shuts off on your 1999 Chevy Suburban when driving?
Alternator is most likely going bad. Does your car start right back up after this happens? If your alternator is bad your car is trying to run on pure battery power and getting zero if little charge from your alternator. When this happens little by little your car will run out of power to everything and in turn shut off.
