Did it turn over after it stopped running??? Could be too many differant things to list. But i would start by checking for loose or rusted wires going from battery to alternator and starter. Also make sure the ground wire (usually attached to the block) is tight.
If the engine is running, then no. The alternator constantly keeps the battery charged.
Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving. You can test this by jump starting your car with another car and after your car is running you should be able to disconnect your battery and car should still run off the alternator. If your car stops than your alternator is RS. Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving.

If it is running on the battery only then that means the alternator is not charging the battery.
Check alternator out-put Hook a volt meter up to battery With engine running reading should be 13.8-14.2 If under this alternator not charging battery sufficiently
Your alternator is probably not keeping the battery charged while the car is running. You need a new alternator!!
It sounds like the alternator is bad. If the alternator is bad the battery will not hold charge when running
If the alternator fails, it is no longer keeping the battery charged and your engine is running on nothing but battery power. Once the battery runs down, your engine will no longer run.
its the alternator if the car is running with a battery light on. but check fuses first
If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good. If it stalls and dies as soon as you unhook the battery then the alternator is not good.If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good.

Battery keeps running down when you are driving. Your battery light should be on if the alternator is bad. Check the voltage at the battery with a digital DC volt meter set to the 20 volt scale. You should read from 13.5 to 15.5 volts with the engine running at idle. If not the alternator is suspect.
If the alternator is installed incorrectly, yes, it can drain the battery.
If the engine is running and the alternator is good. If the engine is not running, no.
Your alternator is not recharging the battery and is defective.
Alternator is defective or the battery has a dead cell and will not take a charge. Check the voltage at the battery with the engine running. You should have between 13.5-16 volts. Anything less and your alternator is bad.
Not likely, but running the engine with a dead battery can damage some alternators. Always fully charge the battery when installing an alternator.
The alternator may not be charging it enough. With the engine running at an idle check the voltage at the battery with a DC digital voltmeter. It should read from 13.5 to 15.5 Volts. Anymore, or any less, and the alternator is suspect. You might also have a defective battery.
Check your alternator (it charges the battery) If it quits you are running straight off the battery and that won't last long. Also check your belts. If they are loose and slipping your battery won't get carged and your alternator won't work properly
No , just when the engine is running
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
If you can jump it and get it running again, drive it for a few miles and then it dies again, it is the alternator. Buy a new alternator and it will fix the problem assuming you do not have bad connections "wires" in your charging system "your alternator and your battery".
You possibly have a loose alternator belt or the alternator is weak. Check the voltage at the battery with the engine running. It should be 13.5 ? 16 volts. Any less and the alternator is weak and needs replacing. Also make sure the connections at the battery are clean and tight.
I'd check your alternator. Disconnecting the positive terminal while the engine is running will tell you. If the engine dies when you disconnect the battery, it's your alternator. If it keeps running it's something else, like your battery. I had the same problem.
The alternator is run by a belt connected to the engine. When the engine is running the alternator is turning. The alternator is what produces the electrical current that charges the battery & powers everything electrical while the engine is running. the battery is mainly to start the engine.
the battery job is to start the car so the alternator will kick in after the car is running
If the alternator is not charging the battery, then it will eventually go dead If the voltage regulator (in the alternator) is defective it will eventually kill the battery Check the alternator with a voltmeter A fully charged battery (without engine running) should read approx. 12.8 volts With engine running should read 13.8-14.2 volts
