I have a 2006 chevy 2500HD and have a battery drain of 1.2 amps If I don't drive the truck for a few day the battery goes dead. I have pulled all the fuse and unhooked the alternator and electric trailor brake control , but no help. Anybody have any suggestions? Please - - - Updated - - - I looked at other post on this problem and will disconect the starter to see if the drain is there. Great site with good info.
