I have a parasitic draw that drains the battery enough that the truck will not start if I leave it sitting for more than 2 days. I have isolated the draw to the IGN B 50 amp fuse. Draw fluctuates between 60-110 mA until I pull the IGN B 50 amp fuse, then draw drops to a steady 30 mA which is normal. I disconnected my stereo and Sub amps and no change. I have pulled every fuse and relay under the hood, on the interior driver side fuse panel and unplugged all 3 connectors from the BCM and nothing changes unless I pull the IGN B fuse. I cannot seem to find the exact wiring schematic for this circuit. Has anyone experienced this same issue? Any help would be greatly appreciated. Thanks, Dave.
