Hi there, I need help with my car. I just shelled out money and around the holidays I cant really afford it so I was wondering if you guys could help me out. My cars warranty has been up for 3 weeks and my car decides to act up now. 2 days after my warranty was up, I was at the store and I went out to start my car and it wouldnt start. My lights, radio and locks worked but it wouldnt start and made a clicking noise. Well my mom told me to check my battery terminals to make sure they werent corroded and I did and they were crusty so I scrubbed them and the car started right up. Well yesterday, I came out of work and it did the same darn thing. So I popped the hood, grabbed a scrub brush and cleaned them the best I could and it still wouldnt work. I again had lights, radio, locks but it still made the clicking noise. Well my friend jumped it and it started right up. Well I just shelled out $80 for a battery and I am afraid it will happen again. Could it be something else? Please help me out!

Your heading is an attention grabber. But don't feel bad about being "Female and Clueless". I've known and dealt with numerous persons of the other gender with really dead space between his temples.
I answered another inquiry with the following text, on another Taurus Forum. I copy and paste as not to retype the whole thing. I realize some of this may be technical, so don't be discouraged. You mentioned you cleaned the terminals. Make sure you take the terminals off and clean where the wire terminal makes contact with the lead post. Just cleaning the outside is cosmetic and will do little to help your situation. Sounds like your issue is battery related, but in case you need info on the alternator too, read on. Now here is the paste from an answer to another forum based on your similar issue:

First thing you need to do is examine the battery and make sure it passes a voltage and load test. Hold off on any alternator testing until you do the following:

Be absolutely sure the battery terminals are clean where they mate with the battery posts. Examine the terminals really well to be sure they are in good condition. If you have a fully charged battery, place a voltmeter terminal (probe) on the (++) lead post and the other voltmeter probe on the metal portion of the battery wire terminal itself. In other words, the voltmeter probes will be about 1 inch apart. One touching the lead post, one touching the terminal metal. Disable the ignition by disconnecting the ignition coil (should be on top of the valve cover.) Crank the engine for about 2 seconds and monitor any voltage fluctuation on the meter. Anything more than 1 volt: Go back to cleaning or get new terminals. For the Neg (--) terminal, do the same thing, but go from the Neg Batt lead terminal to the engine block.

Now that we've ruled out the battery and posts, do another voltage test on the alternator, engine running. Be aware, though, there are two types of alternators, and they are not interchangeable. One type has three wires on the larger quick disconnect. This type of alternator puts out a continuous 14.5 volts. If your alternator is "bad", aftermarket alternators will work fine.
The other type of alternator has 4 wires at the quick disconnect. This type of alternator has its output controlled by the Body Control Module. Voltages may range from 12.5 volts to 14.5 volts, depending on vehicle electrical requirements. Run the engine, turn on all accessories, Air Conditioning at full blast, brake lights, high beams, etc. If voltage falls below 12.3 or 12.4 volts at idle, replace alternator.

Word of advice: 4-wire alternator? Go with Motorcraft unless you want to practice your alternator replacement skills a few times. Aftermarket 4-wire alternators just don't work well unless you get lucky. (I can speak from personal experience. Replaced 4-wire alternator with 3 different units from 3 different stores. Then I went with Motorcraft and. Bingo!
Alternator charging.
