Just setting for a week can run the battery down. you need to make sure that your grounds are good, that your alternator is charging at the proper rate and that the voltage regulator is working properly. If all of this is good then you can start unplugging things that drain the battery, radio, power door locks, interior lights etc.. Or if you know how to use a multimeter you take measurements to try to figure out what is draining the battery. Just be aware that a bad ground and all of the stuff that is contantly on (clock, radio memory, ECU memeory...) will drain the battery some. the process of driving the auto daily maintians the battery charge. The newer the vehicle the more power they usually draw an a daily basis. With out further info it is impossible to know what is going on.
A raidator in need of a flush will not cause a battery drain.
The wrong spark plug wire(s) can cause engine problems including not running but won't drain the battery.
A dead cell in the battery will cause it to loose it's charge overnight. The only fix is to replace the battery. Any light that is staying on will drain the battery. Also a stuck relay will drain the battery.
Yes it can.
Dead cell in the battery. Something on which is drawing power from the battery. Stuck relay.
there is a short some where in the electrical system... or a bad battery.
If it stays on all the time it will drain the battery
A short in the wiring.
Dead cell in the battery, any light on the car that is staying on, or a stuck relay.
dead cell in the battery or something is on pulling power from the battery.
no it doesn't Corrosion on the top of a car battery can allow electrical flow from one post to the other which will drain the battery.
A dead cell in the battery itself will cause it to drain overnight. The battery must be replaced if it has a dead cell. Also any light that is on will cause this. Brake, dome, under hood, trunk, glove box, etc. A relay that is stuck closed is another cause.
how do u drain your gas tank of a 08 ford f350
no , only the concrete and other cemented floors ....
No, a bad coil will not drain the battery.
Yes, a dead cell in the battery or something is on drawing power from the battery.
No, it can cause you to use and excesive amount of fuel but it will not effect the battery.
If no light is on and no relay is stuck then the battery has a dead cell and needs replacing.
A dead cell in the battery will cause the battery to loose it's charge overnight. The battery must be replaced if this is the case. Also, any light that is on will drain the battery. A stuck relay will also drain it. Disconnect the negative cable at night in the dark and if you see a spark of any size then something is on. You will see a very tiny spark which is normal but look for a spark that show a large power draw.
Almost anything. On newer model vehicles, the engine's computer drains the battery constantly, as does the stereo. Short circuits can cause a drain. Any electrical system that is left on will drain the battery. Even a disconnected battery will lose charge over time and the older the battery, the faster it drains. Also a battery with a dead cell will discharge itself, usually overnight.
Shorted diodes in the alternator.
Your alternator could be bad.
at the age of 13 and up
Any relay could be the cause.
