how do you hook up a Sony cdx-c480 car stereo?

[endless phone menu]

Hi, it has red, yellow, dark blue, light blue and a bunch of speaker
wires. If I hook up red and yellow to +12v and bk to -12v a rattling
sound like a stuck cd happens but the faceplate doesn't light up.
Nothing else connected. Any ideas? It's a free-bee but it looks like
it was a pretty decent deck at one time. I read the light blue is a
mute you can connect to a cell phone that turns off sound to the
player. Thanks and keep up the good work.

Oh boy, i hope you mean "red and yellow to +12v and bk to ground" .This
is being done in a car right ?, "red and yellow to +12v and bk to -12v
" could mean a potential difference of 24 volts which would wreck the
unit.
The red wire is supposed to be connected to the "Acc" or accessories
terminal which is basically switched +12v coming via the ignition
switch. Yellow should go directly to battery +ve., Black to ground.

Really have you connected +12V and -12V ? If you did this, probably you have
fried a fuse or the entire carstereo.

There are two fuseboxes : one in a little box contains a 5A fuse, a big
diode and a transformer. If you blow the fuse, change it. There's also a .5A
fuse in the 12 SUPPLY LINE. Some stereos also have a car-type fuse in the
rear just under the connector. If you want the pinout of the proprietary
Sony XR-4400 or for a Philips CD922, ask also.

Thank you all. Yes, I meant the negative pole of a 12v battery, not
-12v. Me culpa. So,... from your pinout my hookup should have lit the
screen with digits, correct? I reset the button inside the faceplate.
Is there a diagnostic button combo for this type of thing? I get 4.89v
on some of the faceplate pins with the faceplate removed. no 12v
reading.

+12 MEMORY YELLOW

this is to keep a clock and the radio stations from resetting?

REMOTE BLUE

what's a remote? Do I need one for the unit to operate? Will it not
turn on without it?

Thanks I got an XR-1300 for free too. No action there either. I fount
a 4A in the redline fuseholder. I'm used to seeing 2A or so. Also in
the junk pile was a Kenwood RR-500E and an alpine CDA-7839. Any info
on these would be great. Non of these lite up because the output
stages were shorted at some point? Is that the most common source of
failure for these things? Why would I hear something try to motor but
get no LED? Thanks again and bye for now.

Normally yes - if you don't hook it up, the radio will probably work.
However I have seen one Delco radio where this line seemed to do a lot
more than just keep the clock and memory working; you had to hook it up
for the radio to operate. If there is a "big" fuse (say, 3 A or more)
in this wire and a "small" fuse (say, 1 A or less) in the red supply
wire, then that's another clue that the yellow wire is powering most of
the radio and the red wire is just telling it when to turn on and off
with the ignition key.

turn on without it?

Usually this is used to turn on a power antenna or external amplifier.
It should have 12 volts only when the stereo is on (in any mode,
tuner/CD/tape). You usually can't get much power from this line - it's
designed to operate maybe a couple of relays, tops. Usually it doesn't
affect anything if you leave this wire disconnected.

check.

You might try sequencing the "supply" and "memory" wires like they would
be in a car. In other words, hook up the black (ground) and yellow
(memory) wires to the battery, but leave the red (supply) wire
disconnected for a few seconds. Then hook up the red (supply) wire to
the battery.

You may be able to get more hookup information in rec.audio.car . Once
you're sure it's hooked up right, if it still doesn't work, then post
back here.

No, this is a sort of "standby voltage" it's needed for keep in memory
stations and hour, but it's also needed during normal work. Connect this to
normal +12. Connect the normal +12 to the ingnition key... or if you want
radio also when engine's off, connect +12 STBY and +12 POWER toghether to
the battery.

what's a remote? Do I need one for the unit to operate? Will it not
turn on without it?

No, it's a 300mA output to the motor of the automatic antenna. If you don't
have one, leave this alone.

I removed it from my old car... it has a "10" fuse, maybe 10A ??? To test
it, connect RED+YELLOW to +12V and BLACK to ground.

on these would be great. Non of these lite up because the output

Maybe there's a problem with the internal psu/filter... but if i didn't have
in my hands the unit i can help you, sorry.
