If you charge the battery and than let it run by itself, the battery will begin to slowly drain without recharging itself as you press the gas.
I'm going through what I believe is a busted alternator right now. Give me an hour and I'll tell you how it went.
your alternator is bad
bad battery, and bad alternator not keeping it charged - also bad connections to the battery or loose wire connections on the alternator.
a bad alternator or battery or both
You car battery, or the connections to it, are bad. It can run on the alternator once engine is going.
Bad battery. I'd put money on it.
The battery will run down and he engine will stop. You will not be able to start the engine. The alternator keeps the battery fully charged.
Turn car on remove positive battery terminal if car turns off alternator is bad
Defective alternator.
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.
Typically you know your alternator is out when you have to jump start your car numerous times. A way you can test it is by turning on your car and while it's running discount the + terminal. If the car turns off then your alternator is bad. If the car remains in then alternator is good and possible bad battery. Hope this helps
If the car won't start it is usually the battery, starter or could be the altenator. What are the symptoms when you try to start it, is there any power?
could be the alternator. could be the battery, the alternator charges the battery but does not stop the battery holding a charge.could also be a bad starter motor. take alternator off and have it tested. most places will test for free
