Checking battery voltage:
  1. Put your key in the ignition and turn the key as if you are going to start the engine. Don't go so far as to attempt to actually start it.
  2. Are your headlights on? If not turn them on.
  3. Check to see if your headlights came on. If they did not come on open the hood.
  4. Examine your Jeep battery for corrosion, which will look like white crust around the terminals.
  5. Carefully scrape off the white crust with a screwdriver that has a plastic or rubber handle. Only touch the plastic part of the screwdriver if you are testing the starter. Be very careful not to get it on your skin or clothing. Do not touch any part of the battery with your bare hands as battery acid eats through clothing and skin.
  6. Check the cables that run from the battery to the rest of the engine. Do any look loose? If they are loose or disconnected press them into the connecting slot.
  7. Try your headlights again. If they do not turn on try jump starting your Jeep battery.

It's important to test the battery before you just replace it. 

Is your Battery Light on?
The battery light is designed to tell you that there is not enough voltage to properly charge the battery, or that the battery itself is not holding the proper voltage.

Do you have an absolute Dead Battery?
Outside of the battery warning light, a dead battery is the most common symptom of a bad alternator.  As the alternator can no longer supply your Jeep with an enough power supply, it will begin to feed off of the reserve in the battery further draining your battery. Once your battery reserve hits a certain level, your Jeep will begin to run irregularly and when the key is turned it will no longer start.

Do you have an engine that stalls?
As described above, a bad alternator will drain your Jeep's battery fast. When the battery gets this dead, it will no longer be able to power your Jeep's ignition system. As the ignition system is no longer able to produce a full spark, the engine will begin to sputter and stall.
If you find yourself in a position where you suspect that your voltage is dropping, but you need to safely get off the highway, turn off everything that you possibly can.  Turn off EVERYTHING that requires juice: the radio, daytime running lights, air conditioning, the blower, heated seats, etc.  That will allow all of the limited voltage in the battery to go to the ignition system.

Are your headlights dimming?
Dimming headlights are one of the most common signs of a bad alternator in the Jeep Wrangler.  Dim headlights indicate that the alternator can't keep up with the energy needed for the lights.  As your Wrangler begins to eat through the voltage stored in the battery, the headlights will begin to fade.
