1984 300SD: Battery drain due to fuse 15.

Dear friends:

I noticed that my 1984 300SD completely would completely lose all of its juice if I did not drive it for about 3 or 4 days. I checked the battery drain by sequentically removing each fuse and finally pinpointed that the culprit is the fuse 15 (8 A white fuse), which is responsible for the following equipments:
--------------------------------
-Trunk light
-Roof light front and rear
-Illumination vanity mirror
-Safety belt handover arm
-Door lights
-Automatic antenna
-Warning monitor term. 5 <=== exactly as shown in the fuse diagram
--------------------------------

I removed the trunk light bulb, turned off roof light front and rear, illumination vanity mirror, closed all doors, and disabled power to the automatic antenna. However, the current drain from the fuse 15 is always about 1030 mA (about 1 A, so it explains why my battery completely lost all juice after 3 or 4 days).

I suspect that the safety belt handover arm and the warning monitor term(. 5) are the real culprits. However, I have no idea what and where the safety belf handover arm or the warning monitor term is. Could someone give me some hints or clues?

Thanks a lot.

Best regards,

Eric

Could be the car alarm. I don't think the door locks work off this circuit, but I suppose you could unplug the lock motor (it's in the trunk under the floor cover) and see if that fixes it. I'd bet it draws more than 1A though.

I don't have a wiring diagram for the W126, so cannot help more than that.
