The battery charge light comes on and eventually your battery dies Then Replace the alternator and within a few days the light comes on again What could prevent a good alternator from charging the bat?
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 alt. You may also have a battery drain (something that is staying on and killing the battery)
Is automotive current ac or DC?
D.C. - from a battery kept on recharge from the alternator. The alternator itself, as its name says, produces a.c., but this is fed into a rectifier included within the alternator case.
How do you repair a 1990 Ford Bronco if the battery goes dead within a week even when new?
Check your alternator, that would be the main problem i think because the alternator charges your battery when in use, and with a bad alternator, means that your car is runnin soley off the battery and does not recharge the battery. Look into getting a new alternator. try testing the alternator at a local auto parts store, another test you could do is start the vehicle , and while it is running take off the battery cables, if motor turns off immediatly then your answer is that you have a bad alternator
Your 1996 Nissan Maxima won't start up at all Not certain if it's battery or alternator drained the battery soon as you try to start nothing ABS light was on before?
The ABS light is likely coming on because the voltage being put out by your battery isn't enough to satisfy the requirements of the ABS system. It could be either the battery or the alternator. Put a load test on the battery and make sure that's operating within the requirements, and put a volt meter on the battery after starting the car to see the alternator recharging the battery. I've seen it both ways, alternator is bad and need a new one, or the battery is bad and need a new one.
Can the alternator kill the battery?
Yes.Normally, the alternator charges the battery as you drive, and if if doesn't work, the battery never gets charged causing the battery to discharge. A discharged battery will have a short life, and is more likely to freeze in cold weather which ruins the battery completely. Note that an alternator should always be tested hot (within 5 minutes after driving for at least 45 minutes) . A bad alternator with a bad voltage regulator or rectifier diode may test good when cold.In some cases, an alternator may be "bad" because a rectifier diode (internal part like a check valve for electricity) no longer functions. With a bad diode, the alternator can, from time to time, actively discharge the battery when you shut the car off depending on the (effectively random) position at which it stops.
The battery on my aurora drains really quick when i turn on anything electrical how do i fix it?
You either have a weak battery that needs replacement or you alternator is defective. Start the engine and check the voltage at the battery with a volt meter. It should read from 13.5-16 volts. Anything less and the alternator needs replacing. If it is reading within that range the battery is defective. Another possibility is a defective battery cable that is swollen or frayed.
What could be causing my battery to go dead within a day or so after a full charge it's a 5 year battery and have only had it for less than a year?
A short in the car's electrical system, a bad alternator OR a bad battery.
Why would your 2004 Trailblazer all of a sudden go dead when you are driving?
If its totally dead (no radio, no starter) I would first look at your alternator/battery. This happened to my 2003 Trailblazer, and we had to replace the serpentine belt and the alternator. Battery light came on while driving and within ten minutes, the car was dead.
What could drain the power from the battery within 24 hrs after installing a new alternator and battery?
Bad starter.. direct ground..... stero equipment IG: amplifier being improperly wired . and it is possible to have the wrong alternator or a faulty one.

Why would a 1994 Lincoln Continental drain all the power out of the battery within one minute of starting the engine?
Good chances are, the alternator is not connected correctly or is defective.
What is the purpose of the fan or alternator belt?
Any belt in a car assists in moving all parts within the engine to work in providing power and cooling to vehicle. The alternator provides power to the battery and the fan cools the radiator so the engine will not overheat.
What would cause a 1992 Chrysler New Yorker to drain the battery if the car is not driven within two days if the ambient temperature is above 70 degrees?
Check alternator
