Cold starting issues can be a little difficult to find; usually it's something basic such as weak spark, insufficient fuel or low compression.
First, run a compression test. If the compression is low you'll have difficulty getting the engine to start when it's cold.
Second, make sure the sensors are all working properly. If it's "computer controlled" and the computer doesn't know that the engine is cold, it won't inject enough fuel to start when cold.
Third, some engines have an additional injector for cold starts; make sure it's working properly.
And last, make sure the starting circuits are functioning properly; some vehicles engage a separate circuit for the coil when the starter is engaged. If that's not functioning properly you won't get a strong spark and you'll have difficulty starting when cold.
if anything is running off the battery (visibly on) the battery will eventually go dead
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
if your alternator is gone or going your car will start and then eventually just stop running because your battery has gone dead. it typically will not make any sound when your engine is not running because of a dead battery.
If you use the radio without the engine running you will eventually discharge the power from the battery. It should be fine for a couple of hours, If not, your battery may need replacing.
Your putting a charge on the battery when its running.
An alternator is the part of an automobile that generates the power to run the radio, headlights, speakers, and air conditioning as well as any other electronic component in the car while the engine is running. This is different from when the engine is not running. When the engine is not running, the 12 Volt car battery operates these electronics. Unfortunately, every battery will die eventually, so the alternator also recharges the battery while the engine is running. This is a slow process, though. But unless the battery is charged, the engine usually can't ever be started.
If it is running on the battery only then that means the alternator is not charging the battery.
One possiblity could be that the charging system has failed and you were running off battery power only, eventually the battery goes dead and so does the car.
A light in your car might be on, running down the battery!!
In a laptop, your computer battery keeps your computer running when it isn't plugged in. The batteries on a laptop will eventually run out and will automatically recharge when you plug your laptop back in. With a desktop computer, a small battery keeps your computers internal clock powered when your computer is not plugged in.
A battery is used to start a car. Once it is running, the alternator then supplies electrical energy to charge the battery as well as power the electrical systems in the car. Removing the battery while the car is running will not affect the running of the car.
The light is telling you that there is a problem with the charging system. You are running off the battery and will eventually get stuck with a dead battery if you continue to drive that vehicle with the battery light on. Drive to your local auto parts store and they will test the charging system for you at no cost. You are probably in need of an alternator.
No , for the battery to be charged the engine must be running . This means that your alternator , if it's functioning properly , is charging the car's battery as the engine is on/running .
It should come back after running the engine if the battery is good.
the reason its still running is because your battery has transferred some juice into it already give life for a short period of time.
Your alternator is not recharging the battery and is defective.
No, that will have no effect on the battery.
Batteries make electricity by a chemical reaction. Eventually the reaction completes and the battery is said to have run down or gone dead. A car's alternator or generator charges the battery by reversing the reaction while the engine is running.
It sounds like the alternator is bad. If the alternator is bad the battery will not hold charge when running
The computer's power, or its ability to stay powered on and running, is maintained by the charge in the battery. The battery's electricity is used by the computer to keep running. If there is no charge in the battery, or the battery is removed, the computer will shut off and will not be able to be powered up.
By running the engine on the vehicle or by connecting the battery to a 12 volt battery charger.
You should read from 13.5 to 14 volts at the battery when the car is running.
No , just when the engine is running
If your alternator stops working you are powering the vehicle on your battery and your battery is not being charged by your faulty alternator so eventually as the battery drains down the car will stop running. Avoid using any electrical power...ie...lights, power windows ect and get your alternator repaired immediatley.
