I would check the Cooling Fan Switch/Relay. Sounds like it is a bad switch and stays 'on' well after it is needed, if it is running the battery down.
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 .
engine cooling fan should not do this - bad temp sensor likely
If the engine is running and the alternator is good. If the engine is not running, no.
If it is running on the battery only then that means the alternator is not charging the battery.
No , just when the engine is running
Yes, and disconnecting the battery while the engine is running can severely damage the computers
By running the engine on the vehicle or by connecting the battery to a 12 volt battery charger.
Get engine running. While the engine is running disconect the POSITIVE termninal from the battery. If the engine dies, the Alterntor is bad.
Yes, because your engine is on.
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
Bad alternator- not charging battery enough to keep vehicle running check with a volt meter A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
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.
If your engine is running , and the battery light comes on , that indicates that your battery is not being charged
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.
Sounds like the cooling fan doing its work. To protect the engine and cooling system, many fans stay on for a short time after engine switch off.
yes the engine runs the charger/alternator as long as the engine is running the battery should be chargeing
No. To erase codes form an OBD-1 vehicle (made before 1996), the engine does not need to be running.On a side note, NEVER disconnect the battery while the engine is running; it will damage the computer.
It should come back after running the engine if the battery is good.
Engine overheating or cooling fan running all the time.
With a scan too or with a battery disconnect.
You should read 12.6 volts with a digital volt meter on a fully charged battery with the engine not running.
use a voltmeter A fully charged 12v battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 volts with engine running
Age of battery Battery will not hold a charge (check with a volt meter) A fully charged battery should read approx. 12.8 volts (without engine running) If charging system is working properly reading should increase to approx. 13.8-14.2 with engine running. If voltage does not increase with engine running could be a problem with charging system of battery is defective and will not take or hold a charge
It shouldn't. When the engine is running, electricity is supplied by the alternator, not the battery. If the engine dies when the battery is disconnected, the battery and/or some related part (such as the voltage regulator) is bad.
