A stuck relay in the car can drain the battery. A dead cell in the battery itself will drain the battery overnight. If this is the case the battery must be replaced as there is no way to fix it. To find out disconnect the negative battery cable for around 8 hours. If the battery goes dead it has a dead cell. If not then something is draining the battery. Anyplace that sells batteries can test the battery for you.
Yes possible. If switch does not open on engine shut down battery will drain If switch does not close on start up battery will not charge
my radio kept cycling for some reason drained my battery. i pulled the fuse and haven't had a radio or clock since, but my battery is fine.
All batteries will drain a small amount, even if they are not being used. However, a substantial battery drain would be due to a problem with the battery or laptop. Make sure that the laptop is indeed off, though. With Vista, clicking the power button in the start menu will not shut down the laptop, but will instead put it into sleep mode. This continues to drain the battery. Some of the lights on the computer will still be lit when the laptop is in sleep mode, while no lights will be on if the laptop is turned off.
It is designed to stay on. It will not drain your battery.
Why do interior lights stay on when engine is shut off on 2001 Lincoln Continental car?
It could be done. You'd have to shut it off if you had the engine off and didn't have an APU running, because it would drain the battery very quickly.
Well not the starter. The starter is used to start spinning the engine and draws its power from the battery. The alternator uses the engines belt to recharge the battery and to power the cars electronics as well as lights. When you shut the engine off, the power then draws from the battery.
Depending on if it overheats, yes but otherwise it will just drain its battery and shut down
you could have a short some where causing it to drain the battery. or the hatch or doors are not shut keeping the lights on in the car.
The battery is dead, or the battery terminals are loose.
Bad battery? Bad Voltage regulator Disconnect the - battery terminal Install a test lamp between the - battery terminal and - battery cable--if light lights there is an extreme parasitic load on battery Remove 1 fuse at a time from the fuse block until the light goes out. This will at least tell you which circuit needs further investigation
It is normal operation. With "key on engine off" the check engine light should be illuminated so you can observe that it is properly functioning.
