I wrote 037.8......the 3.7 ref was an "if" situation. Review my opening post.

The battery is fresh as were a few that came before it. Left connected it will drain in a handful of days...maybe a week. 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.
