The only path to ground should be via the MS -- in at the sensor ground pin (pin 19 in my case) and out by the other connected ground pins. So the sensors should be completely isolated if the MS is unplugged. If there is a path to ground, something's wrong.
[*]I think the installation manual could be improved by including Peter's simple check when the harness is about to be plugged in.
I'd added the note to the manual last week
Where do you think this page should this be linked from to help direct most users there? (I've added a few links to that new page, but not that many yet.)
