S197 won't start
 

I have an 06 Mustang GT. I changed the alternator and the s-belt 2 days ago and the car was running fine. I just tried to start it, pushed the clutch pedal in and nothing happens. I still have power, but my dash flickers and there are no sounds. Any ideas?

Dead battery, bad wire connection or new alternator not charging battery. What was the reason you changed the alternator? Can you jump start your car? What is the voltage at the battery before and after you get it jump started?

I changed the alternator out because it went bad. I have about 85,000 miles on my car. Im working on cleaning all my connections now and then I'm going to try again.
