simple question

Hi Chuck
 If you are not sure of the polarity of the socket,
you can power up with the part removed. This way you
can check the power leads. As I recall, most of the
Dallas parts have 5 volts on the highest numbered
pin and gound at the other corner.
 If you are putting a new clock in, you may need to
cause the clock to start. Most are shipped in a disabled
mode and require a write to one of the control registers
to start them. Check a Dallas spec sheet.
