2005 V6 battery going dead

[ToddR2]

I have not been able to enjoy my ride, because the goes dead within one day. So, I’m constantly charging the battery. Just replaced the battery, so it’s new. Please help, what is causing the battery to drain so fast?
Thank You, Todd

Replace the alternator.

Replace the alternator.

There may be nothing wrong with the alternator, especially if the battery is just draining overnight without the engine running.
Since the battery is new, I'd say the most likely problem is a parasitic draw, and the most common cause is a faulty factory Shaker system.
Search YouTube for a video on how to check for a parasitic draw. You'll need a digital multimeter so if you don't have one, go buy one. It'll be worth its weight in gold.
