The battery keeps going dead and even with the battery and fuses disconnected, the car is still showing 12 volts. Is this a fuse box problem?

If this happens even when the battery is disconnected - its likely the battery is no good..
Any car battery has around a 3 year life span give or take..

Have a great day !

The battery is bad. Almost any battery, unless tone dead, will read 12 Volts when there is no load attached. But put even the smallest load on it and the voltage can fall to that magic 7-8 volt range where things just stop working. If the battery is not that old, you'd best to a charging system check as well to ensure that the battery is not being discharged constantly during operation.

It may be easier to just disconnect the battery at night. You could even buy a disconnect switch.
The siren is powered by a 10 or 15amp fuse number 12, but you would still have the hazard lights flashing. That is a different fuse. The actual keyless entry and alarm module gets power from several sources.

New battery went dead. pulled the fuses and checked for a short. Found the fuse that shows a short just don't know what it goes too


A voltmeter is NOT the correct tool to check for an "ignition-off draw". A voltmeter will show 12 volts if ANYTHING is operating.

There are some things that are SUPPOSED to keep operating when the vehicle is shut off. These include, but are not limited to:
> Powertrain Control Module keep-alive memory
> Radio preset memory
> Clock
> Security/ alarm system
> Remote control recievers (door locks, etc.)

What you need to know is how many AMPS are being drawn from the battery when the vehicle is shut off. This is done by using a shunt bar connected between the battery terminal and the battery cable connector.

Set the ammeter to the lowest setting (usually 2 or 5 amp scale) Connect the ammeter leads accross the shunt bar. Turn off all electrical accessories, ignition switch, etc. and wait for a minimum of 45 minutes for all of the computer systems to go into "sleep" mode. Then open the shunt bar and read the amperage.

The "rule of thumb" is 300 milliamps (or 0.3 amps). This is where you have a problem. Anything less than this is not a problem and is not the cause of your dead battery. My experience is that most vehicles built in the last 15 years or so, will usually measure around 150 milliamps if there is no aftermarket equipment installed. Please note that even this 150 milliamps will measure as 12 volts if measured with a volt meter. A 2 amp draw will also measure as 12 volts....However, a 2 amp draw will kill your battery overnight and the 150 milliamp draw won't.

Battery problems


Well, something is on if the battery is dead. Pull the interior light fuse, and the clock fuse, disconnect the negative battery cable and put a 12 volt test light between the battery terminal and the cable...Likely it will light. Then pull fuses one at a time and observe if the light goes out. Keep disconnecting until you get the light to go out. Do not rule out the new alternator, stuff happens.

Battery keeps going dead. Have had 3 new altanators & 1 new battery. 5 mechanics has worked on it over the last 12 mos.has cost quit a bit of $. but still same thing. Seems to go down when setting over...


Try disconnecting the battery after you park the car in the evening. If there is a short, then the battery should still be good in the morning. if not, the battery is no good. Most common sources of shorts are the alternator ,or the starter. Good luck You take a voltmeter and take a reading across the battery posts. There should be no power on in the vehicle at all...everything turned off and key in the off position. A normal reading may between 12 and 14 volts. Record this reading in a notebook. Now..go pull a fuse in the fuse box. Just one..and go back and take another reading at the voltmeter. Was there any change? No? Pull another fuse. Now you have two fuses out. Take another reading. At some point...that reading will change. It will show an increased reading. You have just found which circuit is causing the drain. With the drain removed the available battery voltage will go up. just follow the affected curcuit, until you find the drain. if alternator curcuit is ok!! then you should have at least 14.2-14.7 volts at battery when running with everything off. good-day ! and good-luck!

I have no electric power to the car anywhere. i have 12 volts going into the fuse box but nothing at the fuses can you help?


If there is 12 volts going to the fuse box,it would have to be in the fuse box,remove the fuse box(disconnect the battery)and flip it over,and you will see the problem.

My dome light wouldn't shut off, removed fuse, but battery still keeps dying


A Battery "DRAW" Test Should be Performed.
TOOL:: >With A 12 Volt Test Light
Disconnect GROUND Cable @ Battery, Connect TESTLIGHT CLIP End to CABLE End And PROBE TO The Battery, The LIGHT SHOULD Come ON.
KEEP IT ON AND MONITERED While Removing 1 by 1 the FUSES In Main Fuse BOX, Untill the Light Goes OFF.
When It DOES you have FOUND the CURCIUT that is Draining your Battery. Take Nessasary Steps to Correct THAT Problem and You Have Fixed the Problem.
THIS IS ALL AFTER INSURING THAT THE BATTERY IS CHARGED AND TESTED. a DEAD CELL IN THE BATTERY will MASK ITSELF WITH THIS TROUBLE DISCRIPTION

Draw on battery when car on


First disconnect the battery overnight just to make sure the battery is not self discharging......if it's dead or down in charge while disconnected....time for a new one.
Now.....if the battery is good....disconnect one battery cable and place a 12 volt test light between the cable and the battery post the cable had just been attached to. A bright light means a drain in the car.
Your job is to remove one fuse at a time until the light dims.
A dim light is OK...clock memory etc.
Remember....a open car door is a drain......the dome light.....so keep them closed while pulling fuses.
Also....if the fuses don't show a drain......disconnect ALL wires from the alternator....there could be a drain there.
Just keep disconnecting one thing at a time until the light goes out or dims.

Brand new battery is dead with nothing left on. Bad ground?


Remove positive battery terminal from battery & put a 12 volt test light in line between cable & battery post. As long as 12 volt light is illuminated, you have a draw. Start pulling & re-installing fuses, one at a time,until you see it dim or go out. If it goes out, you found your draw. If it dims, slight draw, such as radio memory etc. if all else fails, make sure you know where they all go, then pull them all, and start putting back one at a time. When light comes on bright, you found the circuit causing the draw.
