1990 300SE - power failure.
 

Last few weeks, I noticed that the interior lights took a few seconds to illuminate after I opened my driver's door.

Delay of about 4 seconds.

Didn't think anything of this- figured it was the cold weather moving into town.

Tonight I get in the car, notice the delay before the interior lights turn on- ignore it as it hasn't yet caused a problem.

I turn the key and all power goes out. No start, nothing.

I went out and checked things a few hours later: lights come on after I open the door- same 4 second delay- turn the key towards start position and all electric goes dead.

Any ideas?

Car has started every time for me the last 8 years.

Dissapointed.

leaving town tomorrow to visit family for thanksgiving- flying so no car needed.

Car drove great the day before.

Strange. Weather related? Temps have dropped here in NC lately.

THanks.

Check and clean ground cable connections!
