Battery goes dead after car sits for 3-4 days

Have changed the battery,had the alternator checked and has been to a local shop approx 9+ times . Circuits were tested and cannot find the area causing the battery to go dead. All interior and ext light circuits tested, radio, power seats, cig lighters, a/c circuits. Need some ideas.

    Did find that a short was there, but cannot find out what is connected to the fuse block that has the short. the fuse is marked elec I/p, not sure where this goes. It looks like the radio, a/c and interior

    lights. Not sure where else.

    i recently bought a 1992 buick park avenue. But, after being fully charged, the battery lasts for only 4 days or so. I took it to some one and get the battery tested. He said the battery is good, and the alternator/regulator is also good. But the problem still persists. what shall i do?

Parasitic drain? If so, did they run a test light on the negative terminal? Unhook the negative battery cable, run a test light between the negative battery post and the negative (removed) cable end. Does the light come on? If so, remove each fuse, one at a time, when you hit the circuit that is draining, the light will go off.

I have a 95 Buick Roadmaster and it was doing the same thing. It was a broken light in the trunk, the bulb was out, but the electricity was still there. The wire became damaged when my daughter overloaded the trunk. Just a couple of ideas...

    I just remembered (reading one of the other comments) that my 1992 Buick had a drain that took me forever to find. It was the bulb in the glove compartment...the kicker was it wasn't blown.



    We know the elec l/p circuit is the culprit. I suggest turning EVERYTHING on in the car, with help from a couple of people pull the fuse and watch what goes out. Go from there...



    I have had drains on many circuits where the fuses didn't blow.

Have you check the following?

FROM: Lusty Kid


Glove compartment light, does it go off or stays on when you close the glove compartment

Same thing for the trunk light. Does it goes off when you close the trunk, and the same applies to the hood.

If your circuits are good and no shorts exist, most likely you have a light that is not going off

    I need to know the color of the wire. Ex: White with Blue Stripe designated as B/R or White with blue circled stripes designated WB.



    You might also want to check is there any chaffing on the line (somewhere where the wire has worn out the insulation and slightly touching the car body)

    2nd Comment:



    If the fuse is not blowing out, the the circuit is good. Suggest also you check the switch in the ceiling interior light. They sometimes short out although they work, causing a drain on the battery.



    If you fixed the short you said you found in the trunk, then the problem should be solved. If you still are having a dead battery, check the positive (red) cable from the battery to the starter, ensure no isulation is slightly rubbing.



    All that being good, is time to run continuity test on wiring,



    Last but not least. Check your starter solenoid, on the starter, perhaps is staying connected even though it has release.



    Don't know if you have a separate voltage regulator on this vehicle If you do have a separate voltage regulator check to see if its good. Will wait for your responses.

Why is battery draining ford 2002 Taurus SES


Remove negative cable from battery, connect a test light to negative terminal, opposite end off light to negative battery post. ( let sit for 3 to 5 minutes). Then start pulling fuses, when the light goes out that's your bad circuit. God-Bless! Its worth a try.

If i keep the negitive connecter on the battery it will go dead in a hour there is not a wire hooked up on the alternator but i dont know where it might go?


Even with the wire removed, are you saying it goes dead while driving or just sitting . if it goes dead wile driving then the alternator may not be charging the battery as you drive but if it goes dead while the car sits then there is a draw some where.
if you sent me the year make and model with the engine size and also let me know when it goes dead in 1 hour, while driving or car just sitting and i will help you solve the problem. good day

I brought a brand new battery and dorve the car for one day. The nexy day I cranked up my car and the battery was dead.


Have your alternator checked and at the same time have the battery checked at your local Auto Zone or O'Reilly auto parts store. Or auto parts store similar to one of those. Sometimes when your battery goes dead it tends to wreak havoc on the alternator which can cause the battery to not hold its charge.

Brand new battery keeps running down. I'll jump it off, and two days later, battery is dead. Today, the A/C went out. Are these problems connected? What's running my battery down? Is It a belt issue?


It's probably your alternator. When your alternator isn't working properly your battery provides all or most of the car's electrical power. Until you can replace the alternator you can disconnect one of your battery cables while the car is not in use and that will prevent the battery running down. One way to check if your alternator is the problem is to disconnect the negative battery cable while the car is running. If the car goes dead, it is very likely an alternator problem. It usually requires about an hour of labor to replace an alternator. Most alternators can be rebuilt at an alternator repair shop and that is cheaper than buying a new or re-manufactured one.

I left my truck rest for 12 days when I returned and drove it 50 miles the battery light came on and the elecrical gauge dropped to between 9 and 14. I drove it home another 34 miles and when I got home...


Likely a battery problem. Batteries tend to fail when they sit for a while. If your electrical guage was reading 9 - 14, with a dead battery, the alternator was working. Also, if the alternator was dead, you'd likely have noticed dimming headlights and other electrical issues.

But, you could take the battery to AutoZone and let them check it - free.

Good alternator & battery, but battery goes dead just sitting


The regulator could be sticking in the alternator. Unplug the alternator and see if the battery goes dead. I replaced an alternator once and the new regulator was bad.

My battery be drained


I agree with you, it sounds like the alternator isn't charging the battery. Most parts stores offer free check of your charging system, with advice on what is wrong and what needs to be replaced (you should replace your mechanic along with your alternator.)
