Much help! I have a 2002 Silverado LS ext cab, 5.3. I have a parasitic draw. Isolated to “IGN B” 50 amp fuse under hood. Draw fluctuates from 60-110mA until I remove fuse. Then draw drops to a steady 30 mA which should be normal. I have pulled every fuse, relay, all 3 BCM connectors and disconnected all power wires to stereo amp. I have a Chilton manual and have googled but cannot find a schematic for this “IGN B” fuse so I don’t know what to trace. Any ideas would greatly be appreciated. Thanks, Dave.
