Question about 2007 Nissan Altima 2.5

1 Answer

What Systems draw power when the car is off?

Came out to the car one morning to find the battery completely dead. Got a jump start and it ran fine until it sat again over night (starting and stopping multiple times before bed). Got another jump start in the morning and replaced battery. Worked well for one maybe two days until again the car battery was completely dead in the morning. What is draining my battery while i sleep?

Have to do a Parasitic Current Drain Test, to find
the circuit with the fault,then component test items
in that circuit

You have a module,relay or other item, not timing out
or going to sleep

You can have failed switches in the doors,failed alternator
diodes,many things that can cause that

Even the Evap System, which on some cars, run tests while
your sleeping, can be at fault

Check for OBD Codes in all Modules, with professional scan tool,
then do the drain test, leaving the doors closed

SOURCE: Nissan Wont hold a charge

Hi. this is defiantly a slow or major drain that is occurring within this vehicle. Here is a test that you can preform that will help you find this battery drain so you can illuminate this issue.



--BATTERY DRAINAGE TEST PROCEDURE--


Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.


Please rate and god bless:)

SOURCE: Car Battery draining over night

Something is shorted and it could be very difficult to find sometimes. It could be something as simple as a button being pressed when it shouldn't turning on a light or feature that runs all the time, but in a 2001 that is unlikely as it should turn off all lights after a certain period of time. It could be something in the radio. What I suggest is to pull one fuse at a time for accessories, check your manual for what each fuse powers. If the battery still drains with that fuse out then put it back in a pull another. When you find the fuse that allows your battery to keep it's charge then you will have a much smaller field of offending components.

For example, if you pull the fuse that powers the radio and heater, and the battery keeps it's charge then you know it is either the heater or radio causing your problem.

This can take a few weeks to do completly but won't cost you a penny to do.

Your alternator is dead/dying. Nissan puts both of those lights on to tell you that the alternator isn't charging your battery.

SOURCE: Intermittent battery dead.

This fix only applies to diesel engines.
I believe this is a common problem. I'm on my third alternator and third battery!
And there is NOTHING wrong with either of them.
I have just today checked if the glow plugs were turning off, and hello! they are staying on! and sucking more juice than the alternator can supply.
This can be easily checked - either with a multimeter at the glow plug rail, or multimeter or LED battery/alternator tester on the battery locate the 80amp fuse for the glow plugs and pull the fuse while the engine is running - my bet is the battery will instantly be charging normally, and show low volts when the fuse is reinserted.
On my Terrano, the fuse box is half way between the battery and the fire-wall.
The glow plug relay is between the battery and the fuse box - the relay clicks in and out with the fuse removal, which makes me suspect the glow plug controller.
I haven't located the controller yet.
The American workshop manual does not cover the diesel engine model.
The Nissan diesel engine manual does not cover the electrics (glow plugs).
If I can not locate or repair the glow plug controller, I will simply add a small electrical kit-set timer, at the fuse/relay, to turn off 15 to 30 seconds after the ignition is turned on.
Hope this gives an answer to this frustrating (and expensive) problem.

Most likely you have a bad battery. The second option is that you have a faulty wiring and there is a constant load that takes a lot of power, but it does not make a short circuit. Check the electrical relays, maybe it's in them.

Battery dead - car will not start or be jumped started


Change the battery. Newer batteries sometimes go all at once, and are so dead even a jump start won't work. It has happened to me twice. Once you put in the new battery check the alt output with a volt meter should read about 14.5 volts at the battery. If it does problem solved just reset the clock, radio etc.

When your car battery goes dead for no apparent reason, Occasionally something is drawing power that’s not of your doing. This is a parasitic draw, and it can cause the same result as leaving the headlights on. To read more on this type of battery drain please visit my blog

It could very well be a defective battery, you could have 1 or more bad cells in the battery. A voltage regulator or an alternator. If it isn't one of those then there is something drawing power from somewhere that is causing it to go dead.
