[W126 Coupe] Back to the battery drain issue

[Jim Ham]

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: 
bun warmers, windshield washer tips, maybe rear view mirrors. My car is a 
500 so has fewer of these items. You might be able to feel around searching 
for something warm. All that energy is going somewhere.

Regards,

Jim Ham
