After three roadsters over Thirteen years, I now finally have my first battery drain issue. After helping so many others with this "horrible" problem, I now have the problem. I'ts not fixed, but I know what the issue is, I had it isolated in maybe fifteen minutes. So the battery is disconnected until I 'fix' this.

So now we start the game: Guess what the cause is. The only hints are these:
It is NOT the alarm siren.
It isnt any aftermarket item that I've added.
