My wife's new-to-us 2000 C230K has a parasitic drain that has me stumped. After a dead battery, I checked for a drain (ammeter between neg post and frame) with a reading of .27A current. After a couple seconds it would drop to .04A, then .08A, then back to .27A. Pulling 7 different fuses would lower it to .24A, then the cycling again.

Question: What would cause it to cycle like that? (Fuse designations seems to point to the window or door modules)

TIA!!!!!
