O.K. Thanks to you all. I do appreciate the help.
I have to admit, however, that most of your terminology has left me more
confused than enlightened. Sorry, I did say I don't know much.
I do understand, I think that this box may need to be as is, left alone that is,
as it could feed other outlets.
There is a near-by duplex outlet on the same wall that is controlled by a toggle
light switch on the wall, if that is any help.
Anyway, what I THINK, I understand is that I need to turn off power, take off
insulating caps and then turn on the power and use my meter to check --
one-by-one -- any current between the red and white wire.
Then check for current between the black and white wire.
So, what do I do if there is no current -- the current is 110 or the current is
220 -- or the house blows up? ;>
If the circuit breaker trips? Or any of the other things that may happen. Or I
guess I can check and then report back with results.
I think I am at the path here, I just need to take the first steps...
