battery drain need help.

Soo the battery in my 2000 csvt keeps dying it takes about a day to drain from full charge down to just clicking when trying to start. Long story short on how I got here. Car died while driving it got it home alternator was bad changed it and got a new battery.. lasted about a week no problem then the battery drain started again. So got another new alternator and battery (warranty) and still does the same thing. Also the speedometer jumps around some at low speeds that just started. Any idea on what could of happened when changing these two things would be great.

Did you confirm with a multi-meter that you in fact have a draw?

I had the same scenario with a 98 SVT. Read a bunch of threads on here on possible causes and started with the easiest first: the trunk light. Opened the trunk...put the rear seat down...shut the trunk. I'll be damned if the light didn't stay on and not go off after 15 seconds. Pulled the light...power draw eliminated.

Hopefully yours will be as easy.
