Earlier I posted some dumb questions about installing a new doorbell
(have hated forever the cheapo that was there when I bought the
place). Finally got a friend to press the doorbell while I threw
successive breakers. After isolating the right one,
I boldly went where this klutz has never gone before, and installed a
handsome new doorbell!!! How sweet it is! I could stand out there
all day and push the lighted button.
