What is the normal current drain of a "2006 CTS"

Twanika,

So I'm having a similar or maybe the same problem. I have an '04 CTS and the 1 year old battery checked fine but kept dying so Auto zone flat gave me a new battery even though they and I kinda agreed it probably wasn't the battery. The brand new battery does exactly the same thing. So I connected a VOM (in amperage mode) in between the battery and battery cable ensuring I was looking at all the current leaving the battery. I measure 2.5 amps as soon as the battery is connected, then the computer and things trip out after 25 or so seconds and it goes to 25mA, then that goes down to ~14mA after another 10 seconds. So it sits at 14mA. If I unplug the 60A fuse that goes back to the l. Rear (upper middle) of the fuse panel, then it immediately goes to 0mA. So now I'm searching for a wiring diagram to find out what that circuit feeds. If I pull the big cable out just below the large square fuse labeled Body W/H that also knocks out the amperage. Nothing else in the whole fuse panel affects that 14mA draw. So if anyone has a wiring diagram, Hook me up PLEASE. And T, if you figure it out or find the same thing with your system, can you let me know what you did
Thanks in advance for any help..
