190e 2.3-16, does it suffer from slight amp draw when sitting for period of time?

I have a strange question about my 16 valve. Have you had any complaints about this model or any other MB car that has a little amp draw on the battery when sitting idle say for a week? I know there are quite a bit of electronics aboard the car the can account for this.
Thanks
Joe

The car should draw 30milliamps (.030 amps) when EVERYTHING IS OFF. You should test this using a Fluke Meter and run the negative cable to the meter and the other lead of the meter to the groud post of the battery.

What is the source of the .030 milliamp draw? Joe

The clock uses 10-15ma, the rest of the draw comes from COMPUTERS that require just a bit of power for memory.

M.B DOC.
What happen to the computer when the battery is flat ? What are infor in being kept by the
computer memory?
Thanks. AL

The computers will retain their memory for a long period even with the battery disconnected. They use a capacitor for this.
