Hello as of last week I was having what I thought were battery issues. My car wouldn't start, and upon testing it was said that it was time I needed a new battery. A week ago I got my battery replaced at autozone and all was well. Yesterday my car needed a jump again, and all of the power would not work and it was suggested to me that I may need a new alternator. After another jump this morning I made my way to autozone (after testing) to find out that the alternator was fine and I had received a bad battery. After a free replacement I was not half way through the day when once again my car would not start. I am not very knowledgable when it comes to cars and I would just like some appropriate guidance. When I try to start the car it literally does nothing. No clicks, no false or almost starts, the key just turns and there is no noise or anything. Please help.

You're describing the symptoms of a very common problem on all car brands. Follow the smaller positive battery wire to where it is bolted to the under-hood fuse box. Be sure that connection is clean and tight.

When you have metal tools on that nut, be absolutely certain the other end doesn't touch anything else metal on the vehicle. Doing so will create a dead short, and if you're lucky you'll only have a huge shower of sparks. If you're not lucky, the wrench will become welded in place and will turn red hot.

Okay... nothing happens when you turn the key, but when you get a jump, it starts, correct? I need you to check a few things for me. First, I want to make sure the battery terminals are clean and tight. Next, I need you to test the battery. It is easy to do and only requires a multi meter or volt meter. Here are the directions:

If that test good, I need you to get the car started so you can test the alternator. Here are the directions for that:

Let me know the results. Keep in mind, you may just have a starter starting to go bad.
