[QUOTE="Vader's Fury, post: 1023694, member: 473"] With the truck shut off, the doors closed and the interior light out, unhook both your negative terminals on your batteries and hook a test light between the negative post on one of the batteries and the corresponding negative battery cable. If the light comes on, that means something is drawing power when the truck is shut off. I would start pulling fuses until the light goes out. Once that happens, you will know what circuit the short that is drawing power is isolated to. You may need to pull the fuse for the radio before doing this. I can't remember, but I believe it pulls a slight draw on the batteries all the time and will eschew your testing results. If you pull any fuse and the test light dims, you have a draw through that circuit. If you hook the test light up and it does not light up, you have a battery, battery charging issue, not a draw that is killing the batteries. [/QUOTE]
