How do you tell if the alternator is outon a 1999 kia spehia?
A quick way to tell if there might be a problem with an alternator is to remove the positive side battery cable from the battery while the vehicle is idling. If the engine dies, odds are there is an alternator problem.
Does the motor charge the battery when you run the engine?
No, the alternator recharges the battery. Of course the alternator is turned by the engine.
Why does the battery light come on the battery and alternator have been checked and are good It's a 2000 dodge intrepid?
The battery light comes on when the alternator is either over or under charging. If the alternator tested good you have a wiring or computer problem. The engine computer is the voltage regulator.
Why does the battery charging light don't go off after starting the engine of my 1983 Toyota Corolla?
Have the charging system checked. The light comes on when there is a charging system problem. it may be a battery, alternator or a battery problem.
How do you get the alternator to turn over?
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.
You have a brand new battery it discharges right after it is charged again is it the alternator?
Assuming the new battery is good! The usual problem why a battery is not charging is the alternator. The battery will be discharged if the alternator is not working properly when you start the engine and when the engine is running, etc. The vehicle uses the batteries electricity instead of the alternators electrical output, and of course if the battery is not being replenished by the alternator the battery will fail in a short period of time. You should test the alternator to see if it is putting out between 12 and 15 volts. Another possible things that could be the problem with a New battery failing so quick is, maybe the proper amount of acid was not put into the battery, a short in the wiring, etc.
What could cause engine to try shutting down while driving and battery going dead overnight if battery and alternator have been replaced?
Sounds like the engine is using the battery as the source of power instead of using the alternator. The main job of the battery is to give power to the starter that "starts" the engine. Once the engine is started the alternator kicks in to maintain power throughout the vehicle, as well as keeping the battery strong. But if the alternator isn't working, the engine will get it's power from the battery. And without the alternator keeping the battery strong, the battery will die. Note: between the alternator and the battery, there is a voltage regulator, this make sure that the battery only gets the power it needs. Oh, one more note, here's a way to tell if the alternator is working properly. (Start the engine, while it is running remove one of the battery cable for just a few seconds.)if the engine stops, then you have an alternator problem still. Check your wires. Or replace the unit. for more answers. email tjjjlong@aol.com A constant 12 volt drain on the electrical system, even when the car is off
Should your car start right after changing the alternator?
If the battery is fully charged and the starter is working properly it will turn over and start. The alternators sole purpose is to supply voltage to the vehicle and battery when the engine is running. When the engine is not running the alternator has nothing to do with starting the engine. If the alternator went bad and the battery was discharged then you will have to charge the battery before it will be able to start the engine. Do not jump start the engine with a dead battery if you can avoid it. This puts a strain on the alternator trying to recharge a dead battery and can damage the alternator, even a new one.
What cause alternator not to produce power to start engine?
The alternator produces power to charge the battery. The battery powers the starter to turn the engine over.
When an alternator is bad what happens to your car?
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.
Will your alternator recharge your battery if you let it sit for a while?
If the engine is running and the alternator is good. If the engine is not running, no.
Why does check engine light come on and battery gauge go down in 1993 town and country minivan but problem goes away after a jump start?
The battery is basicly used just to start your vehicle, the alternator is what generates your power once the vehicle is running. Which indicates you need a new battery, not an alternator. That is why you problem goes away after a jump start(boost). If it was the alternator the problem would not go away and your vehicle would have no lights and stall with no start. Either your battery is bad or the alternator is not charging.
