999 ford taurus if it sits for 2 or 3 days the battery is dead how do you track a short

On my car if I don't drive it every day the battery goes dead to the point that you can not recharge it. I put in a battery disconnect so that if I'm not going to drive it I turn the knob and my battery doesn't go dead. I've put in 3 batteries

    i had a bronco once.shut it off and the fog lights stayed lit.was a stuck relay.was easy to diagnose since you saw the lights on.other electrical devices might stick on and not be so obvious.example door locks.think your doing the right thing with shut off for of luck.

    disconnect negitive battery cable connect test light between negative battery cable and negative battery terminal disconnect anything and everything electrical in the car when light goes out on thet light you will know nothing is draining the battery start with the light under hood and in trunk they are usually the problem but you may have to pull realys under hood if one is stuck .if none of these seem to be your problem dosconnect the alternator the regulator may be bad and cause your problem . remember when the test light is lit your draining the battery. keep disconecting until your is off.

Yes, possible something is drawing current when it should not. With everything off, car not running, ignition in off postion, key out of car: Test: Disconnect / loosen bolt and slide off the negative terminal from battery post and place an AMP METER in series between negative battery post and the negative battery wire you just disconnected. You are trying to see if there is any leakage current being drawn when all is "OFF" and how much that is. It should be very very small or practically nothing. Like no more than a few milliamps if anything at all. You can use the current setting of a Digital Meter. I figure if you read more than a few milliamps with all OFF - that is too much.
THE OTHER POSSIBILITY - is you have a problem with your alternator, and it is overcharging the battery when you drive. Driving too much voltage into the battery or not regulating the charging of the battery properly - not ramping down charge properly as the battery reaches full charge. That could KILL batteries one after the other - as you drive. Real solution there is to have the charging system of your car checked by an expert. POSSIBLE - charging problem / regulator problem / alternator problem (overcharging while driving or not proper charge regulation) - suspect - something bad in the alternator or regulator circuitry - may also be drawing current when OFF, and discharging the battery when not running.
Your battery disconnect switch - may help with the discharging problem - but you may still be killing batteries when running through improper re-charging.

Use a volt meter or test light, disconnect the negative battery cable from the battery post. If the meter reads 12 volts or if the test light is lit start pulling one fuse at a time until the meter reads zero or the test light goes out.

Make note of what circuit the fuse protects then start working your way back from there. It cold be as simple as a dome light being left on but you need to narrow down where the problem may be located.

I hope this helps, good luck!

SOURCE: 2003 Ford Taurus, 90K, used car, engines shakes, ABS goes on

Are you getting any codes from the Check Engine Light? This sounds like it could have something to do with a sensor. Check your air filter and make sure it's clean. The tach on my 1999 doesn't really work, but it hasn't coincided with other driveability problems. The engine doesn't change in it's RPM's, the tachometer just stops working. Have your charging system checked. The shaking might be coming from bad fuel pump operation, clogged fuel filter, or dirty fuel injectors. Try putting an additive into your gastank to clean the injectors (a bottle of Seafoam is great for this). Try calling your local Autozone and see if they do free trouble code scanning. This might help lead you in a better direction.

SOURCE: Battery keeps dying on 2001 Ford Windstar.

Check your battery terminals make sure they are clean and corrosion free.
Also check all ...A-L-L courtesy lights in your car. there are some ceiling mounted lights that are passenger operated and may be on... Also check your glove compartment and consoles for lights.
Also check for charger cords... These have indicator lights and sometimes can drain the batt as well.
Also, under the hood, is a gravity activated lamp . Open the hood and make sure that it's going off and staying off as the hood closes...
Let me know if you find anything...

My ford f150 has a new battery and starts fine all day untill it sits all night then its dead

Someone will need to pull the fuses and disconnect the major electrical components until you find the power drain. You use a meter or test light to watch the battery voltage. It could be anything from a stuck relay, to a short in the wiring.

Battery keeps going dead

Does it go dead after sitting for a few hours? Once started and driven for several miles will it restart if the engine is shutoff? If the battery goes dead only after sitting for a while with the engine off, you probably have a bulb or some accessory that is draining the battery.

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 have a 1999 Mercury Sable and accidentally installed the battery backwards. Replaced blow fuses and the car ran fine. After sitting idle for 3 days, returned to find the new battery dead. A jump start...

Check and make sure your termimals to the battery are clean and tight. You can find out if the alternator is charging by simply starting the car and while it is running take the negitive cable off the battery. If the car quits its not charging (have the alternator check) if the car keeps running it is working properly. If it is charging and all your termimals are tight and clean you may have shorted out the battery and ruined it by hooking it up backwards. Good luck

99 Taurus dies quickly and random windshield wipers

Its sounding like you have an electrical short in the car. These are the hardest things to track down. Basically the home test you can do is with a basic test light. Disconect your possative lead from your battery and *short* the conection with your test light. Clip on the clamp touch the point to the posative battery terminal. With the car off it that light comes on super bright you have a short to start tracking down.
