You can have somebody check out your Voltage Regulator, that is fairly common in Ford Explorers, especially with the 4.2L V6. If that tests ok, go to any parts store, they can run an electrical system test, which is usually free, or up to $20.00USD. Also, if you have a system in your truck, make sure that your remote wire from your deck, is connected properly to your amp, to shut it off with your stereo. If your amp runs continuously, it is bound to drain your power.
usually means that the alternator is not charging. So the battery is being drained.
my 05' cavalier has a bad alternator problem its charging the battery a little bit then stops and the little power my battery has is drained by the end of the night. I replaced the alternator twice and the battery but still no difference.
Check all earth connections Have the battery heavy discharge tested (Drop tested)
the positive wire that recharges the battery after being drained from the starter
dead cell in the battery or something is on that is pulling power from the battery.
The alternator died first and drained your battery shortly thereafter.
Sorry to say,but no. The alternator is the device that replaces the power that has been used from your battery.Without the alternator, the battery will get drained and not be able to recharge.
A bad alternator will have the effect of draining the battery, resulting in dim lights, trouble starting the car and the like. It would be best to replace the alternator as soon as possible and possibly obtain a new battery. This may vary depending on how much the bad alternator has drained it. You can get your alternator and battery checked any time at Auto Zone.
have you checked the alternator??? that's the first thing that comes to my mind if your battery is being drained
When the alternator goes bad or goes out completely, the car's battery will be drained. I suggest you pull the alternator and have it tested. If the alternator is bad, you will most likely need a new battery as well. The cost is around $200.00.
Your alternator has failed, and the battery has drained from running the vehicle without being able to recharge it. Replace the alternator and the battery should be fine.
No, you must have a charged battery for the alternator to work.Here's an explanation of how the charging system works:http://www.ricksfreeautorepairadvice.com/repair-topics/alternator-generator/testing-an-alternator-without-blowing-it-sky-high
Its probably not the battery, its more than likely the alternator that isn't keeping the charge, to check it turn your car on and the unplug the battery, if it stays on then its something else, but if it turns off then get a new alternator
Chances are you drained your battery when your alternator failed to maintain your cars regular running functions. You should take the battery to your local auto parts store, they should be able to test it for free.
I would suspect a bad alternator and battery, have them both checked at the parts store. A car with a fully charged battery and a bad alternator will run until the battery is drained and then quit.
It's most probably the alternator. It's not putting any charge back in the battery. Can also be a dead cell in the battery or something is on pulling power from the battery.
Take the battery to a parts store so they can test it.... Actually you need to test both the battery and the alternator because if your alternator is not functioning correctly it can drain the battery of power... so just testing the battery may only tell you that you have a drained battery and not reveal the cause... This testing can be done using an Auto meter which tests the battery and also does an alternator load test...If you do not have a tester you can rent one from an auto parts store,or you can remove the alternator and take it to the auto parts store and have it bench tested along with the battery...usually for free...
Even a new battery cannot start and run the vehicle for long without the charge it needs from the alternator. The battery has a certain amount of reserve power meant to start the vehicle only, then the power supplied by the alternator keeps a constant flow of power going to the battery to keep it charged enough to run the electrical system of the car. The electrical system, especially in late model vehicles pulls a large amount of electricity, so without that constant flow to replace the high draw, the battery is drained of its reserve. If you have driven the vehicle with a malfunctioning alternator, then parked it, chances are there is just not enough power to turn the vehicle over and start it again, as it has been drained completly.If you charged the battery on a charger, it would,(if a bad alternator is your problem)start and run the vehicle again, but just until the battery is drained.
You don't need an alternator to start your engine only to recharge the battery. You could start any vehicle without an alternator but that doesn't mean it will run for long. Newer vehicles would just run till the battery was drained.
check battery cable connection to see if loose.could also be a drain on battery,check to be sure all accessories were turned off overnight. Just a few days ago my caddy would not start. the battery checked out ok, but the alternator was bad. diodes were bad causing an "open loop" in electrical circuit which drained battery. To check alternator, first fullycharge battery, take to local parts store (autozone will check it for free)this can be done with alternator on running engine. Good luck!
Some symptoms of a car alternator failure include dim headlights, a drained battery, or the inability to start the vehicle. The alternator powers all aspects of the electrical system once the engine is running.
I had this problem on a 1979 Mercury Grand Marquis- it turned out to be a short in the wire going from the alternator to the battery. It was intermittent, so it was very hard to run down. If the alternator checks good, the short/broken wire could easily be the culprit.Rocky_B - See my entry here for more things you might want to check: http://wiki.answers.com/Q/What_could_be_wrong_if_the_battery_light_stays_on_and_the_battery_still_runs_down_on_a_1996_windstar_after_installing_a_new_battery_and_alternator
Yes, the car will start with a fully charged battery. But if the alternator is defective the battery will soon run down and the engine will stop once all electrical power is drained from the battery. You can drive maybe 15 miles in daylight with nothing on, or maybe 10 miles at night with your lights on.
A 1997 Ford Explorer might lose power for a variety of reasons. It is possible that a light was left on and the battery was drained. Or, it could just be time for a new battery, and the old one randomly gave up the ghost.
The battery indicator lamp illuminating usually means that the battery is not receiving or accepting a charge from the alternator and is being drained past an unsatisfactory state of charge.
