Something is draining the battery. When the car is off it is still pulling from the battery about 1.4 amps and 2days the battery is flat . What is draining the battery?

Do u have a car alarm, clock, etc. Cars do have systems that draw electricity even wen off. U could put tester on battery, than pull out fuses one by one, checking the tester each time to c if draw stops. It least it may show system involved. How old is battery too is a question too. I replace mine every 3 or 4 years for that very reason. They weaken year by year.

I used a battery tester and pulled the fuses one by one. It did not show any problem. No draw stopped, so now what is pulling the battery down. I replaced the battery with a new battery and it drained the new battery flat.

U typically have bank of fuses inside car and under hood too. Did u check both? How bout car alarm? Is it fused seperately and if so did u check that as a possibility? Is your ignition switch perhaps some how being left in a on position? Did u check lights and make sure there not on. Sounds like a draw that is drawing lot of power. I would start with obvious things first. Maybe disconnecting bulbs and c if draws stops. Let us know...curious!

I have 3 fuses boxes. 2 under the hood and 1 in the side of the dash on the drivers side. I check every fuse and no draw stops. No lights left on or the ignition switch not left in the on position. So I am lost to what to do next. In order from draining the battery when I am not driving it for a few days; I disconnect the battery cable.

Did u add something after market that might b doing it? An alarm, tow hitch, anything? Did u put test light between hot cable and hot side of battery? Wen testing was EVERYTHING off? Including having the door shut or a hood light etc. The only thing I can think of that makes a somewhat direct connect is starter (try testing it too with light) or after market add ons. I'm really curious now, let us know wat u find. Again to test u need things you know are on (door, etc) to be off. Look at cig lighter too. Maybe other guys out other have more ideas. Does it have alarm? Is it fused desperately?

Meant...is it fused separately?

I know I'm answering a post that's 6 months old now .... But the Crossfire does have a towing sensor that detects if the back end is lifted up to try to tow it that's part of the alarm system. That's located in the trunk after you pull the inside carpeting material out to get to it. I never messed with mine but I'm told if your trunk leaks and enough rain water gets down in there, it can short it out and cause these battery drain issues. I think it has a harness on it you can disconnect, in the trunk, to troubleshoot that.

I am having the same issue with my 04. Really frustrating. I bought a new battery and new alternator and still the battery is dead by morning.

I'm having the same problem with my 2004. It is intermittent.

Just bought ANOTHER new battery for my 2005...and it STILL dies within a few days of non-driving!

I see I’m not the only one with this battery drain issue. I feel for all those that have electrical issues with these cars and there can be many but I still like my crossfire’s. I have 4 of them at the moment. 1 base model and 3 SRT 6’s. I could write a small book on what I’ve learned and yet I probably don’t know 1% of the electrical system. 1 of my SRT’s has this battery drain issue much worse than the other 3 cars. 2 or 3 days and it’s battery is dead. The other 3 are good for about a month or possibly a little more. So if I know I won’t be driving 1 for a couple of weeks I disconnect the battery. I should mention that you can buy battery disconnect switch’s fairly cheap at an auto store that go right on the battery post and then it only takes a second to disconnect it. But of course you still have to lift your hood or if you have an extra 100 or so you can buy a wireless one which is controlled by a keychain push button. I’m getting a little off topic here. Now I’m not sure if these posts have a word limit. I don’t want to write another 100 words just to find it won’t get posted so I’ll end now and write another one right away with what I found out about this issue

Ok I’m back. I’ll be honest that have haven’t read ever single post here so I might be repeating something that someone has already stated. You can NOT use a test light to diagnose this issue. You must use a amp meter. As there are multiple battery drains and you will never get the test light to go out by removing 1 fuse at a time. I’m going to assume that if your battery is dead in 2 days that you have at least a total of a 2 amp draw. Now it’s been over a year since I diagnosed mine and I can’t remember many details I’m afraid. But I’m sure I remember finding 4 separate draws. (1) is the remote entry system. (Door locks) (1) is the alarm system. (You have to push the button twice to turn it on, so try it both on and off ) (1) is the radio. Now I should mention that the car that gives me the worst trouble has the navigation system option built into the radio. I haven’t taken the time yet to compare the draw from the basic radios in the other cars but I believe that I though it was rather high for a radio. The 4th draw I found was that one of the previous owners had installed a GPS tracking system in the car. It was very cleverly hidden in the trunk next to the air pump that supplies all the locks on the car. Now that’s a whole nother topic as many of the crossfire owners have door lock issues and most can be traced to simply a broken or leaking air line and most times its at the pump itself. Now back to the GPS tracking draw. It made me scratch my head in curiosity. As it cycles on and off. So the amp meter would constantly fluctuate. Now as Puchie noted early in a post. There are 3 fuse boxes on the crossfire and in some cases there is more than 1 fuse for 1 function. As you go down the list of fuses and what they do and protect. You will find that a single function is listed twice. ie. the windshield wipers and washer I believe are listed twice. Please don’t ask me to explain that in writing. I won’t live that long :) I don’t no if what I’ve said has helped anyone or not. I do plan in the future. To compare all the battery draws from all the cars for each of the components so I have a baseline as to what is normal and what is malfunctioning. I will mention one other thing and that is on a battery. Even if your battery is fairly new. If you kill your battery (stone dead as they say) about 6 times or so. By that time your so called new battery will be lucky to have 75% of it capacity lift. Once you’ve kill that battery 10 times or more it won’t have 50% of it original holding capacity even at full charge. This makes the draws appear to be getting worse. You used to have 4 days and now it’s dead in 2. And the battery is only a few months old. Ok I’m going to end this post now before I venture in the crossfire’s ECM problems. Which aren’t that hard to fix but you need a lot of patience !!

Interested in learning what you found after a few months. My 2004 XF has the dreaded parasitic drain. I thought by pulling fuse 9 and checking and detecting that it was possibly the theft control module that would fix it. But after a week my new battery is dead. Ala_Fire in AL recommended pulling the alarm siren under the cowl and wipers. Pretty frustrating indeed. Any other readers have idea most welcome. Thx.

I don't know why but my battery drain seems to be related to the spoiler. Every time it goes crazy, up and down and up and down the battery is dead within two days. Even a fetter daily driving

I found mine to be related to the spoiler. Once I disconnected, no more issues with the battery. The wiring harness is located in the trunk just under the spoiler. I still have not traced it back to see if a short is the problem, we just don't used the spoiler anymore. I spoke with engineer about not using spoiler at high speed and he said it would not be a problem. Only reason I'm back to this FAQ I because I am having issues with the convertible top. No electrical power, not related to spoiler disconnect. Any ideas?

I've read numerous examples of things that can cause an electrical discharge. Someone also suggested a component that was installed on the battery terminal that could disconnect the battery. On my various cars that were stored without use for periods of time, I had devices that were affixed to the battery terminal with a protruding threaded stud that allowed for a connection using a wing nut. Modifying the battery cable by pressing an eyelet shaped copper fitting onto the bare end of the battery cable allowed for quick attachment & removal of the cable from the threaded stud fitting on the battery using the wingnut. These were often used in boating. However, I also remember guys using heavy duty electrical breaker box type switches that were installed in the ground wire run somewhere between the frame grounding & negative battery terminal connection so the breaker switch would act to connect & disconnect the battery's ground. Researching the internet may find remote operating devices designed for this purpose.

Ya'll need to pull out the alarm module from under the wiper cowl for starters... or replace it with a new one if that's your flavor. You also need to pull up your hatch carpet, remove the Styrofoam storage box, and see how much water your door lock module might be sitting in. The towing sensor is included in the door lock module and it can permanently short itself out when it gets wet.

I know this post is originally over 7yrs old, and last post was about a year ago . BUT same problem with my 2006 crossfire conv. started after new top installed ,new battery was no help. never ran down dead . So I started by ,pulled Styrofoam out of trunk, all dry there, no sign of any water whatsoever , and module/lock pump sets on its own small platform with at least a 1 inch thick fiber barrier around it all , no sign of ever being wet (stains). could not find the alarm module under wiper cowl ? maybe had already been removed ? IDK I remember reading in the owners manual about the spoiler going up when battery is low way back when I replaced the battery for the first time. I will try unplugging it to see if there is a relation to battery draw. lots of wires lead to door lock module , not sure if I should try unplug any of those ? I will keep you updated if I find a solution.

UPDATE spoiler unplugged stopped voltage drop for sure
