Hi Pizzaguy,
First time I measured the current I had 270mAmp, next time when I waiting longer it was 120 to 180 mAmp. I shall do one more measure now after I had remowed the alarm siren, if it goes down to 55 mAmp I think the big drain problem is solved. But can the defective battery in the alarm siren alone take 100 mAmp, that is 1 Watt. In the winter I should see the snow melt above it.

Graphite, wath kind of car was that ? And SE is that the Crossfire from 2007 ? If, then it must have some upgrade of the hardware.

I have the original radio in the car, the one with GPS. I have plans to replaced it with something more modern with SD card and Bluetooth. But hesitate because I also want the car to be original.
