Idle air control? Fuel pump? Coil?
One possible cause is a defective alternator, Have the charging system checked.
not charging the battery properly... check the alternator.
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.
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)
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.
dead cell in the battery or something is on pulling power from the battery.
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
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.
My alternator stopped recharging my battery but I can't take the tension off my serpentine belt to put my alternator back on.
Battery Light OnCheck for bad alternator. alt. is goodbattery is goodchecked fues goodwhat about wiring
The battery light is for low alternator output voltage. Try testing the alternator output using a miltimeter and if its less than 13 volts your alternator isn't putting out what it should. If it has low output check the belt tension and all wire connections before replacing alternator
Every time you disconnect a battery cable you have to reprogram the radio stations ( if that's what you are asking )
Alternator, silenoid, battery cables. After you have checked those 3, try a new battery if its more than 3 years old.
mercury is only used in a mercury battery
Either the battery is very weak or the alternator has bad diodes .
No, a car battery does not have mercury in it. It would be very dangerous to have mercury in a car battery.
