If the alternator is not working the battery gets discharged. In most cars a light will show on the dashboard - battery light icon, and this will suggest fault in the battery or alternator. You will need to start the car and check if it is charging the battery, and most garages will do this check for you

Your 1997 Mazda 626 will not start after an alternator malfunction why?
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.

How do you test the alternator in a Toyota Celica 1990?
simple useful alternator test - with the car running at idle and no accessories, lights, etc. on. Disconnect your positive battery cable. the car should stay running if your alternator is functioning correctly. If it is, leave your battery disconnected from the alternator for the night, or for however long it has been taking to drain the battery. Reconnect in the morning and try to start it. Often alternators fail because a strain is being imposed on them by a battery short. It's good to replace both at the same time.
What will happend if you disconnect the battery terminal from battery while engine is running?
Nothing, if the alternator is good the engine should keep running.On the other hand if the alternator is bad the engine will die/stall. In a modern car with sophisticated controllers (ECM, BCM, TCM, etc.), NEVER DISCONNECT the battery with engine running. These controllers have semiconductor chips that are sensitive to voltage spikes and transients which become pronounced when battery is disconnected.. Even the power diodes in the alternator can be stressed and eventually damaged.

What are symptoms of a bad alternator in 2000 ford explorer sport?
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.
