I've been living with a Quick Disconnect for a good long time because the local MB dealer and independent shops want nothing to do with it. Oddly enough, all of the wide-eyed 19 yr. olds that work in radio/alarm installation shops tell me they can remove the Clifford alarm without issue. This alarm was installed before any of them were born. I doubt they would understand it's construction and more importantly how it interfaces with MB electrical/electronic systems in a 23 yr. old car which is likely why the MB dealer and the indy shops turn and run.
There's a draw somewhere. I'm very suspicious of the alarm or after-market radio, but suspicion is bad science. I'll get to the bottom of this sooner or later.
Thanks for everyone's participation.

You can't expect 19 year olds to understand eight tracks.
The electrics of a 21 year old car is simple enough to make removing a car alarm not that complicated.
If the battery is 55A and drains +/- 40A in week the power drain is (40/7)/24 = 0,23A/H.
If you measure 38mA (0,038A) and your battery is good it can only be an intermitted power drain. These are sometimes hard to find.
You can disable the radio and alarm to check if one of these causes the drain.
Other suspects are the light switches in the "always power on" circuits, like interior, doors, trunk and glove compartment.
If not, a multimeter with a MAX hold option can help to find the problem. If you know how much current is used during the drain it is easier to detect the component.
