2007 Ford Taurus Check Charging System?

01 What is it?

02 Can I fix it myself?

03 How much will it cost please?

This happened the first time 3 weeks ago. And it happened today and I've never had a problem with anything electric or the gauges on the dashboard.

Had it tested at Auto Zone (the battery) and she said it was a bad battery. Took it back where it was purchased still under warranty and he said the battery was good.

I figured I would let my mechanic check it out but the lucky bastard went on a two week cruise two days ago.

It's only happened twice in the 3 years I've owned it. 3 weeks ago and today.

Just looking for ideas so thanks and thumbs up to all who answer… Just give me time to get back and read the answers.

01 What is it? MANY POSSIBLE CAUSES, including charging regulator fault, alternator fault, wiring fault to name just 3

02 Can I fix it myself? NO IDEA OF YOU CAPABILITIES BUT UNLIKELY IF YOU Can't EVEN WORK OUT WHAT IS WRONG WITH IT

03 How much will it cost please? HOW MUCH DOES WHAT COST - fault unknown without inspection and testing
