Actually...

a dead battery doesn't necessarily mean that the battery is faulty.

Recognize that a battery is nothing more than a storage device for electrical energy. The battery will store electrical energy for a relatively long period of time but eventually it will fail.

A battery can become depleted in several ways:

1. the battery is faulty. Common, but not the only problem. Understand that all automotive batteries are manufactured by just a few companies, and different names are put on the batteries allowing companies to make the claim that their battery is better.

2. A battery may become discharged if there is something that uses power when the engine is off. Commonly, a light can be left on, depleting the battery charge. Again, common, but not the only problem.

3. Since a battery is only an electrical energy storage device, something has to put electrical energy back INTO the battery, that's called an alternator. The alternator uses a small amount of the engine's power to generate electrical energy. Technically it converts kinetic energy to electrical energy. The alternator generates enough electrical energy to provide for all of the vehicle's NORMAL electrical needs, and replaces the electrical energy that the starter used to get the engine running.



IF the alternator fails, the battery will eventually discharge and the starter motor will not have enough electrical energy available to start the engine... so it just clicks.

If there is a device that uses a large amount of energy when the engine is off, the battery will eventually discharge and the starter motor will not have enough electrical energy available to start the engine... you get the idea.

If the battery fails, one or more of the cells will stop storing electrical energy, resulting in the starter having insufficient electrical energy to start the engine... so it just clicks.



My recommendation: borrow a battery charger and charge the battery for several hours. The amount of time necessary to charge the battery will depend on the capacity of the charger. A low amperage charger may take quite a while.

You COULD jump-start the vehicle, but make certain that you get the polarity right or you'll destroy the alternator.

After you get the engine started, a quick test of the alternator can be performed by attaching a volt meter to the posts of the battery. You should use a volt meter that is calibrated, so you'll know that you're getting the right reading.

The volt meter should read about 13.5 volts if the alternator is functioning properly. You may need to run the engine RPM's up to about 1,0000 to get a proper reading.

If the voltage is right, turn on a couple high energy consuming devices, such as the headlights and the rear window defroster. If the alternator can maintain 13.5 volts, the alternator is okay.

Whatever you find NOT working should be replaced.

FYI, the comments about Fords vs Chev are nothing more than an indication of individual preference. the simple fact is, even though I consider Fords to be much less reliable, both manufacturers use similar assembly, engineering and part selection procedures.

Number 1. your battery is dead, you have to buy a new battery. Number 2. If you had a Ford, you wouldn't have problems with a 98.

Number 1: check the condition of your cables ( are they clean, are they loose ). Number 2 if you had a ford you wouldnt have these problems....You would have many more problems.....HeHeHe
