'02 Silverado 2500HD - Parasitic Draw?
 
The truck wouldn't start. Recharged the battery. Battery was good. Truck started.

A couple of days later (after sitting): Truck wouldnt start. Had battery checked. Battery was bad. Replaced battery. Had alternator checked. Alternator was good.

Tried parasitic draw test. 1.5A is being drawn (it fluctuates between .6A and 1.5A). Pulled all fuses individually in main fuse box. No change in leak. Pulled all fuses in the interior fuse box. No change.

I also pulled all of the relays with no change in draw.

Anybody have any other theories I could test?

Have you got an aftermarket stereo installed, I have seen stereos with removable faceplates draw over an amp of power when everything shut off and the faceplate is installed

No, I don't have any aftermarket anything. I have disconnected the alternator and starter as well. Same draw. Somebody mentioned the bcm. Not sure what that is or where or how to check it.
