Yes, you should be able to see a wire as I described. If the videos aren't HD it might not be visible.Is that what can be seen in the video with the damper open?
I didn't know where the photo came from as the Google document it was part of didn't load correctly.Nice to see my photo there.
Just to throw this out there...I remember a big stink over what that thing even was. Interesting that it ended up being something that odd...
I'd love to hear it in action. I think it could still be active.
If it's still active, it would be worth recording.
