[W126 Coupe] Back to the battery drain issue

[Markus Meyer]

Negative ground issue ring a bell? 

 Vance,
 
Well, if nobody has any ideas and you are at a loss, why not start pulling fuses and see what happens?  One fuse at a time, a week at a time, and hopefully you can narrow it down to at least what items are the culprit.  Theoretically when you pull the fuse causing the drain, it will stop, right?  I know it may take a bit, but with no other answers...why not!?

This may be off the wall, but it sounds like some heater is coming on to 
keep a regulated temperature. What's heated? I can think of a few things: <BR>bun warmers, windshield washer tips, maybe rear view mirrors. My car is a <BR>500 so has fewer of these items. You might be able to feel around searching <BR>for something warm. All that energy is going somewhere.<BR><BR>Regards,<BR><BR>Jim Ham<BR><BR>At 08:20 AM 2/4/2006, you wrote:<BR>>Well unfortunately, although all evidence pointed to the vacuum pump as <BR>>the cause of this intermittent 6amp current draw.
