This has been plaguing me for about 2 weeks now and I cannot find a solution. My car won't turn over or anything the battery gets so low. I've replaced the alternator twice now and when that didn't work I got a new battery which all of them have remedied the problem for a few days at a time but come again today car won't start saying Charging System Failure. I'm so lost on what this could be. Anyone have suggestions on what to replace next? :/

I think I've got it figured out. I did a test to see how much power was being pulled while the car was off. After the computers shut off I still had a .7-.8 amp drain on my car. Pulled the fuse going to my subs' amp and boom! Down to .02 amps which is perfect! Now I need to figure out why my amp is drawing so much power all of a sudden. I've had it for close to 2 years now and never had a problem with it. Wish me luck! And thanks for the tips.

If the amp drain isn't your issue, there is a 200A fusible link in the power cable that runs to the alternator. If it blows, the alternator will not charge the battery and once it runs down you will be done.
