Dead Battery

[f5fstop]

One thing to check, well a few....
Make sure you cannot move the battery cables (Positive and Negative) where they attach to the battery. Grab the cables at the battery and see if you can move them back and forth. If so, get a 10mm socket and make sure the cam bolts on the cables are as tight as can be. (These new cables are terrible, MY OPINION ONLY, but if loose, they will cause some strange things to happen.)
Make sure the ground bolt on the fender, just behind the battery is tight.


If those are ok, take the vehicle to the dealer and have him run a midtronics test to check the battery. It could be starting to go. They can also check for a large parasitic load that might be draining the battery.
