My wife's Turbo S has recently had a problem with battery draining overnight. I had felt that the battery was getting weak, but it tested as just low charge on a tester at Auto Zone. The alternator keeps the car running all day long. I recently installed a new radio, but ruled it out by pulling the radio fuse overnight, only to find the battery dead again.
I was reading in the forums here and elsewhere about the speed sensor going bad and causing battery drain. I have noticed during a few of the times we have jumped the car off, that the wing will move up and down right as I'm starting the car. Since this is only activated by the speed sensor, or bypass switch, I figure the sensor might be a possible solution to the drain.
My next test is to try the same trick with the fuse. I will pull the fuse that is on the speed sensor circuit, to see if that eliminates the drain.
Any other thought on this issue?
Thanks
