No, but occasionally we have mice and our one-eyed Walker hound hoots gently when he feels like he's not getting enough attention.

I've had people *say* a lot of things that weren't necessarily true

Yeah.  Just remember, we're talking about two or three amps per side
pulling down a 20 ma LED that will light at least a little if the
voltage at 49a gets to below say nine volts.  Which ought to make the
signal bulbs stay lit up, wouldn't you think?

He'll do the tests, and we certainly need the answers.  But for the
moment I'm favoring the poltergeist theory.  Or the phlogiston theory
maybe.  Stephen, do you have any high-strung teenage girls around the
place?  Do plates mysteriously fall out of the china cupboard?
