Thanks for clearing up the reset switch and the mystery position.
Sounds like it may be a bad switch or relay. I was just curious if I
might have a variable delay relay in there now, with some odd way of
setting the delay. I say that only because I have/can get the delay
I'll experiment some more, without the reset switch and see if any
repeatable patterns show up.
Meanwhile, anyone have any recommendations for a variable delay relay
(and which one is it)?
