I've googled this to death but thought I would give this one last
try
here.

I have a 1996 S10 Blazer with Delco radio model #16169165. I can see
that
the previous owner must have installed a different stereo & then
when
they
traded it in, replaced the Delco.

I bought the car a month ago and its fine except the radio memory
does
not
store any station setting or time. It has three plugs- black, blue,
and
white. An orange wire in the black plug supplies 12 volts while the
key
is
in the ignition. There are no other voltages present in any plug
with
the
key off.

With those 3 plugs in the back of the radio there is still one open
socket
with 7 pins I believe. But there are no other loose cables anywhere
to
be
found in the dash. Is the 12 volts necessary to keep the memory
supposed
to
be through this plug?

Unless someone has any ideas, my only hope is to apply 12 volts to
each
of
those pins to see if the memory keeps without frying the radio.

Someone suggested that the radio might have an internal battery, but
I've
taken the covers off and don't see anything resembling a battery.

If you have any ideas please let me know!

TIA, Steve

The only thing to add to and complement all of the previous comments
is that if you are worried about applying 12VDC to a wire to
test......merely do so thru a 470-to-1k 1/2 W carbon resistor as that
wioll be adequate for the miniscule memory retention requirements.
I thought that I had online EBSCO Auto Repair info available , but the
wiring diagram was not inclusive of the radio. Tomorrow I will check
out All Data for
its wiring code colors to the radio.
