I have a problem that is driving nuts, If I park my truck for a couple of days with out starting it then it drains my batteries to the point I can't start it, I have changed batteries, checked for anything stay on and can't find anything but I do see that the light to wait for to start doesn't always come on even after it sets all night. This is a 2006 5.9 cummings Please help!
Grab a multimeter and check the amp load on the battery when the truck is sitting. If it seems excessive, start pulling fuses one-by-one until the amp load drops to a more reasonable level. The system tied to the fuse you pulled will be the first place to look.
Did you come up with any clues as to your battery status yet ? Did you try the parasitic loss or battery load tests yet ? The batteries will need to be charged to test - either by you or a parts centre with a charger.

The same thing is happening with my 09. I brought it to a mechanic and he tested the batteries and tested the draw. I believe he said it was 10-20 milliamps of draw, which is fine. I brought it home and I let it sit for 4-5 days it was stone dead.

My solution to this problem on my 2000 was to install two (very) beefy switches right next to the positive cable of both batteries. If I'm going to leave my truck sitting for anything over two days, I turn the switches off guaranteeing the batteries don't drain. There's got to be a short somewhere, and this is admittedly a PITA fix (long ago stopped bothering resetting the radio)....it's a fix.
