If you have replaced both of these components and it still is a no go - just start looking for things like corroded wires or perhaps a blown fuse. Somthing to do with the alternator. For some reason the juce from the alternator is not getting back to the battery. If you stop at an auto parts store get a Haynes or Chilton manual (they have wiring diagrams in the back) just sit down in a quiet place and study the diagrams......Good Luck.........JeffAnswerMany autoparts will do electrical testing for either a minimal price or even free. That should take the guesswork out of the problem, and likely even save money: replacing perfectly good parts doesn't help (done that more times than I care to admit!)
One possible cause is a defective alternator, Have the charging system checked.
not charging the battery properly... check the alternator.
I can tell you that on a 2000 mercury cougar it is a fuse on the positive cable between the battery and the alternator
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery. You may also have a battery drain (something that is staying on and killing the battery)
The charging system is the alternator which is on and functioning anytime the engine is running. If not, then you have a problem with the alternator.
If your 1997 Mercury Tracer has a battery light that blinks on and off while the car is running, it most likely means that the battery is not charging. This could be an issue with your alternator.
Idle air control? Fuel pump? Coil?
usually that the battery isn't taking a charge. have the alternator checked, many shops will test the charging system for free
Defective alternator, short in battery, or loose or corroded connections.
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.
Get the alternator checked before your battery goes dead.
no it has a stator charging system that uses a rectifier & volt regulator.
A clicking sound when you try to start the car is a dead battery. It may be that the alternator is not charging it properly.
go to a auto parts store like advance auto and have them check your computer to see why it is on. they do this for free. this might give you a idea on why its on. if you havent already.
Needs new alternator.
The most probable cause is that the voltage regulator has failed. The regulator is an integral part of the alternator so you will probably have to replace it.
dead cell in the battery or something is on pulling power from the battery.
The battery light isn't an indicator that the battery is always bad. What the light should really be is a picture of an alternator, but most people wouldn't recognize that. Have the alternator checked off the vehicle to make sure it is good, then have it checked on the vehicle, (many places like Auto Zone do this for free). If it's not charging on the vehicle, you could have an alternator fuse bad or your car might even have an inline fuse between the alternator and battery. Many Ford products have a large fusible link between the alternator and battery, and if it's bad, there is no power going to the battery from the alternator. Good Luck!!!!
Normally it means the alternator is failing.
There is a battery light above the engine temperature gauge
This indicates a no-charge situation. Most likely the alternator is bad.
i have an 87 topaz where the alternator goes bad also. have replaced it twice. it is just a common problem in the topaz's
wires, connecters, terminals
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
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
