Question: Is it the battery, alternator or neither?

I have a 2006 hyundai tuscon wouldn't start a few days ago after sitting for maybe a week or more. We jumped and later had Auto Zone test the battery and alternator, they told me the alternator was bad. That was a few days ago, started up fine today after sitting a couple days. On a whim I took it O'Reilly and they did the same test and said the battery was bad. Strange...any thoughts?

Unfortunately, the people doing those tests probably don't understand the electrical system, and the devices they were using were designed to be idiot-proof, but they're not perfect. So without running tests myself, or at least seeing the output of the previous tests, I can't say what is going on with your vehicle. It sounds like you will have to take it to a shop where you'll pay someone trained to test the system.

And it's always possible that the alternator is bad and it has been wearing out the battery--so they're both on their way out. You'll need data to verify.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
