my battery has been dead every morning for the past month or so when i come out to crank. so i did some troubleshooting with a multi-meter and found a 3.0 amp pull on the batter while the truck is off. i removed fuse 21 "cluster keep alive power" and the amperes dropped down to .050 and below, not quite sure what that means now. or where the next step is....any help is much appretiated. thank you
