Sorry Kevin, I quoted you, but my response was to both of the posts
prior to yours, and then yours as well. JoeSpareBedroom said "Start
over, but spend a couple of hours at the library first, reading some
books about home wiring.", which is obviously not applicable to me.
Also, the meter suggestion is a good one, and I'll try it tonight to
check for bad breakers. I also like the suggestion of turning off all
breakers and then trying each one ON, to see if two of them power my
lights - that's something I hadn't thought of - I only went the other
way turning one at a time OFF. I also did try turning off the main
feed, which did kill the lights (how could it not, right?), but did
not try leaving the main feed on and turning off all breakers
(although I suspect that must have the same effect, since the lights
couldn't be tied to the main feed since it's 240V, right?). One more
question - since the lights are all downstream of a single switch,
which works, I should be able to kill the main power, disconnect that
switch from the circuit and be good to go, right? No power to switch,
no power to lights? That way anything else on that circuit upstream
of the switch would continue to function appropriately and even if
there was a double-circuit connection upstream of the switch, I would
be absolved from having to hunt it down. Sound acceptable or am I
missing someting?
