No set thing.. Take it to a garage. The alternator may be faulty: only voltage of 13 or 13.5 (which is listed as acceptable but is not sufficient to start the battery as well as run headlights etc.), rather than 14 or greater (as is needed for this particular make and model). Another thing you should check is grounding. Be sure connections & ground straps are good. Be sure you have good battery cables & connections.
First start the car then pull off the positive on the battery if the car dies than you need a new alternator if the car keeps running u may need a new battery. A word of caution, testing an alternator that way can cause damage to the alternator. The alternator needs power to make power unlike the old generators from the past.
Battery may have a dead cell and need replacing.
Alternator is not putting out a charge.
yes it will i have a optima battery in my 1995 marquis
No, the battery for a 2005 Jeep Grand Cherokee is available from other sources. The price of the battery will vary depending on the quality of battery you purchase and the installation cost.
Then something is on pulling power from the battery. Check all lights and relays.
a timing chain has broken
Typically, a bad or "going bad" alternator.
If the battery is dead you will need a battery charger. If the battery is good and you have low amperage then you will need another alternator. Most parts stores will check it for you. If you are looking for MORE amperage then you would have to buy a larger amperage alternator.
Remove battery connections, then slacken the serpentine belt. Removal of alternator is simple and straightforward, 3 bolts, replace in reverse order.
This usually means that you have a dead battery. Either from a bad battery, or a bad alternator.
Start engine and measure volts at battery, it should be at least 13

Have you had the alternator checked? If an alternator is not working it can acually drain your batt. big time fast.
it could possibly be the battery or the alternator check both. from the way it sounds that the alternator is going out and is making the battery work to hard and causeing it to go bad it could possibly be the battery or the alternator check both. from the way it sounds that the alternator is going out and is making the battery work to hard and causeing it to go bad
Check the fuel filter if the cars battery and alternator is good it might be the lack of fuel that is bogging the car down. My advice to you would be to check or replace the fuel filter.
Either the battery is very weak or the alternator has bad diodes .
bad ignition switch, bad battery, bad alternator/regulator,
=== === Some types of electrical shorts do cause the battery to discharge. But usually a bad alternator just does not charge the battery. Or does not put a large enough charge back into the battery. This causes the battery to discharge when you start and run the motor. The spark plugs and other things need electricity that would usually come from the alternator is now coming from your battery. If your bad alternator is not recharging the new battery, the battery will soon fail to start or run your vehicle. You need to have your alternator tested. It should be putting out at least 12 volts, usually around 13 to 15 volts.
is your battery in good condition and fully charged? is your starter good?
maybe you need a new alternator
Refer to your owners manual. It should have it listed under battery maintanence If light is still on you probably haven't fixed the problem so it might be your alternator or it could be your 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!!!!
Might be you alternator. Happened on my 1997 grand marq a couple of weeks ago
Bad alternator?Check output with a voltmeter - without engine running battery reading (fully charged) should be around 12.8 With engine running reading should be 13.8-14.2 if not probably a bad alternator
