Maybe a Motion Sensor/Switch gone bad - my experience - long

I had/have a similar problem in my 1987 T900 Convertible. Currently (pun intended) the battery looses 0.08mA per day not bad and the battery has stayed live for over a week of inactivity (don't ask) whereas it would die in much less time. After many rounds of fuse/relay pulling, meter checking, key in ignition/key out of ignition, my problem was the motion sensor On/Off switch!? In the Off position (where I normally left it) the current draw spiked to a high value and in the On position the power draw was reduced. Since the motion sensor shows no continuity difference regardless of its orientation I have left the switch to the On position - totally counter intuitive. To be sure I always have starting power I installed a Sears Security Battery - this battery will discharge to a certain level and then go into a fail-safe mode. Thus a 'bad' current draw, although annoying, is not a problem. As well, it gives me some piece of mind that nobody can start the car and drive it away. If you do find a definitive solution please post it as there are many Saabers with similar problems and another addition to the possible solution list is always a good thing.
