This is a 2003 Mitsubishi Lancer.
Within the last 3 weeks, we have replaced the battery and the alternator. The car ran fine for about a week after replacing the alternator and now it won't start.
We put a batter charger on it for about 2 hours last night and 3 hours this morning. When we tried to start it, it made one click and that was it.
I also noticed that the light that shows a door is open doesn't even come on anymore. When you hook up jumper cables and start to put the 2nd one on, as soon as it touches the battery it makes the same one click sound.
