My car just stopped working all of a sudden. It'll turn over really fast, but the car won't start. Once you charge the battery it starts and runs fine but not even a day later it does the same thing and doesn't start again. Like something is draining the battery. I had the battery and alternator checked out and they were fine. Any ideas?

Hello,

You might have an excessive parasitic draw on the battery.
A parasitic draw is when the battery loses its charge due to a faulty electrical component.
It could be a light that stays on (like a glove box light), or a shorted window switch etc.
