Question about 2003 Ford Expedition

2 Answers

Current drain My battery goes dead after sitting for 4 days. Battery load tests good and charges up enough to start the truck after 15 mins. I can leave the charger on the battery for 4 days and it never drops below 5 amps charge rate indicating a constant current drain. I suspect the alarm system. Its a Code Alarm with remote start. I also have a trailer brake controller. I'm going to remove one fuse a a time to see if I can find a circuit that sparks when I remove the fuse. Does anyone know if this Ford has any electrical issues that may cause this problem? I'm a former auto mechanic with over 20 years of experience and have a strong electrical background.

    This thing will drain a battery to 0 just sitting for a week. Battery load tests good.
    What could be leaking current?

Check the light under the hood, the switch may be bad and the light stay's on all the time and over the visor. Check to make sure the vanity light is off also.  It's just a start and i have known also that the 4X4 actuator will drain too. Keep me posted, be glad to help and it sounds like it's going to be a gremlin to find the battery drain.

    Was going though my CD and found that the wire harness to the electronic 4X4 actuator at the transfer case my get corroded casing a short to the relay casing a constant drain but if your 4X4 is working fine then that harness is ok. Common to happen to high road salt area or near the coast that promote corrosion. I did found a TSB though that os causing to drain the battery. Owners of 2003-07 Ford Expeditions and Lincoln Navigators may experience a dead battery along with a balky rear wiper. The problem is covered by TSB #07-10-13 and can be diagnosed with the following procedure: Pop the rear window open to make sure the wiper mechanism is disengaged from the motor drive plate. Next, open the beauty cover over the wiper arm attaching nut. Then, connect a dial torque wrench to the nut and rotate the wiper arm across the entire length of travel, keeping the blade touching the glass the entire time. Keep the window open during this test. The torque measurement must not exceed 49 INCH pounds. If you discover that it is greater than this amount, replace the rear window striker/wiper pivot shaft assembly. Corrosion on the wiper pivot shaft assembly causes excess torque and prevents the wiper arm from returning to the park position. The wiper system continues to attempt a park maneuver periodically and those continued attempts drain the battery. Hope this helps. Keep me posted, be glad to help.

Have you had the alternator check for a bad diode it may not put out enough to keep the battery charged after 10 to 14 days. The bridge in the alternator could be weak. Hope this helps.

Have a 1994 camry xle a 1997 lexus motor was put in it v6 3000 4 cam 24 the battery goes dead after about two days when the battery is charged it hard to start the starter clicks several times before


You either have a bad battery or something is draining it. A good way to test for this is to remove the pos battery cable from the battery. touch the cable to the battery post to complete the connection. If you hear something pop on, hum, buzz or click, it is staying on draining the battery. Your local auto zone, or advance auto ect will test your battery for free

2004 Dodge Durango. When it set over night there is not enough charge in the battery to turn over the engine. The battery is one and half years old.


Maybe the alternator is not charging the battery up well. To test, put a voltmeter on the battery, engine running. If voltmeter is less than 13.5 volts, suspect a weak alternator-have it tested.
If charging system and alternator is good-charging between 13.5 volts and 14.5 volts, have the battery tested. Even though not old, it may have a dead cell. A parts store can load test it and see.
If battery and alternator are both good, you may have an unintended drain on the battery. You can check this by, first charging up the battery, then leave the negative terminal off the battery overnight. If it starts good next day, there may be a drain, something like a glove box light, an under hood light, a radio amp left on.
Post back if you want help with finding an unintended drain.

Car goes dead


Looks like you are having a battery problem, your battery is weak and not able to hold the cars charge. When u let the car sit the battery will lightly charge itself but once you turn it on and drive it begins to drive, the cars accesories will drain out the battery and the alternator will do its job by charging but the battery is just too weak or it could be the alternator not putting out enough amperage to charge the battery sufficiently, the alternator could be seizing on you when u are driving, stopping and rotating off and on, if thats the case then your car will shut off. I would do a load test on your battery then if that checks out ok then go for the alternator. The load testing tool can be purchased at any AutoZone or Lappens, Pep Boys etc..

Good luck..
