A Hidden Parasite – need help

My 2005 S600 has had a parasitic current loss problem since I purchased it last December. An example of the problem: yesterday with a full charge the battery read 12.67 V at 1PM.at 5PM it read 12.69 V. At 9PM it showed 12.36 V. Then went for a drive to re-charge. History of troubleshooting: I have checked all circuits by monitoring battery amperage draw while removing fuses for each circuit, then observing amperage draw. No problems uncovered – all either zero or less than 60 mA... A Hidden Parasite – need help
