Need Delco radio help..please!!

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 empty socket may be for optional functions-like steering wheel
switches for radio operation, etc. Do not attempt to power up those
terminals. The memory power is probably missing on one of the other
plugs. You should test (not just look at) the fuses in the fuse panel,
and obtain a wiring diagram for the vehicle; possibly a partial one for
the dash circuits. Find the missing KEY OFF supply and restore it.

Hi Steve...

The orange wire should be powered continuously.

Take care.

Yes, the orange is hot at all times.

The empty socket is for bench testing, plugging it into a test jig. Don't
touch it.

Of the three plugs (black, blue, white) the black is for the power. ACC
power on (yellow if I remember correctly), ground (black), orange (hot) and
maybe pink if the car had a power antenna from the factory (no power antenna
= no pink wire) The blue and white plugs are for the front and rear
speakers.
You say the orange has 12+ when the key is in the ignition. How about with
the ignition off? If you are not getting power to the yellow wire with the
ignition in the ACC and ON positions, you may have a blown radio fuse.
Orange wire is fed off of the dome light fuse, powers dome light, cig
lighter and radio memory, hot at all times.

A common problem with GM cars was, when the electric cigarette lighter went
bad, it takes out the fuse. No dome light, no radio memory.

READ THIS! It is possible that when they installed the aftermarket radio,
they cut off the factory plugs. When they decided to put it back, they may
have miswired the plugs
SO to summarize again:

Orange = 12+ constant (batt)
Yellow = 12+ switched
Black = 12- (ground)
Pink (optional, power antenna on)
