94 Corolla ; stereo won't turn on?

[[email protected]]

I just recently bought a 94 Toyota Corolla. As it didn't come with rear
speakers I took it to best Buy and they wired them and installed those
for me.

Anyways, factory AM/FM radio wasn't groovy with me, so I took the JVC
CD Player out of my nissan Stanza which broke down (it was after-market
CD player just to make sure)
Best Buy would charge $90 for some ridiculous reason (brackets, wiring
harness, etc etc) so after some time online I went to Circuit City and
bought the proper wiring and vehicle wiring harness for $25 total.

Took out the stock radio and set about installing the JVC CD Player.
Pluged the wires into the proper spots of the vehicle harness, plugged
that into the radio harness, and that into the CD player. Everything
fits, it IS the proper wires I'm absolutely sure of that and nothing
appears to be loose.

Plugged that in, plugged the antenna wire into the CD player, and
turned the car on. Nothing.

I thought maybe the fuse on the CD player itself went out, checked it,
and even replaced it with a spare I have, and still nothing. Same with
the fuse for the radio on the car itself which I know isn't the
problem, as the radio and lighter are on the same fuse and the lighter
works.


What could POSSIBLY be wrong?
I thought it MIGHT be the Ground, as I had that problem with the CD
player in my last car. It has a black wire that runs through both
harnesses for the ground-wire, but in my other car that was the culprit
and I had no idea what to do so Best Buy split the black wire to
another one and connected that to a metal spot of the frame, and it
worked fine until the car broke down.

If I can't figure anything else out I might try that..I'd hate to split
the wire if it's not necessary but it's better than paying Best Buy
lots of cash to fix it.
I might take it to Best Buy tomorrow anyways to see if they can figure
out what's wrong and what they'd charge to fix it (since it's not an
installation, hopefully cheap or free, depends on what they say)

Since you're "absolutely" sure that your wiring is fine, your cd player must
be broken. Replace the cd player, if the replacement still does not work then
replace the car.

Check and make sure your power lead is actually getting power, that
makes a huge difference.If it is, check the ground a be sure its
sufficient.If that isnt the problem, check and make sure all your
connections are good no loose wire or anything. also did you use
butt-connectors or anything like that that can make a difference,
because with out it your wire can come loose and not have a good
connection.
good luck!

Ha Ha Ha

HE SAID BUTT (said in the voice of Beavis)!!

I said I'm absolutely sure it's the right wires, not that they're fine,
they appear to be fine though.
It got too dark for me to look into it any further tonight without a
decent worklight available, so tomorrow morning I'll look into
everything, I do think the ground wire might be the problem.

I checked the wires from when it was in my Nissan, the ground was split
off from the black wire (labeled as ground on the CD player of course)
to a different wire, and attached to a metal piece of the car of
course. The other side the wire was simply cut, so nothing was going to
wherever that signal would be going.
Maybe with this particular CD player the actual ground-wire doesn't go
where it's intended to.

If you have doubts about your ground, simply clip a wire to the case of the cd
player and attach it to any part of your car that has bare metal or on to a
bolt or screw. Then see if it will turn on.

The only time real installers use butt-connectors is only when there
is no one around that is straight to hold the wires as they get soldered.

You have 2 power wires on that unit, a red and a yellow. the yellow wire may
not be getting power. it has to be 12 volts all the time.
the fuse for that may be under the hood in a fuse box near the battery

Yeah I found that fuse box the other day and just gave it a brief
glance (prior to this problem) so I'll go check that out, test
something for the ground, basically try all these ideas and hopefully
they work.

The colored wiring diagram posted earlier is incorrect for the CD
player I have BTW, I'll try these then I'll write down the wiring
color-code and post that up too.

The wiring diagram posted, is for the car and not the cd player.........

That's what I figured and I appreciate it, seeing as I don't have an
owner's manual.

The problem has been fixed.
The culprit was the "Dome Light" fuse under the hood. I had glanced at
the box but didn't get around to checking fuses yesterday until it was
darker.
So the stereo is in fact working perfectly fine now, thanks a lot
everybody!

Hopefully when I get the rest of the stuff for my sub that'll go
smoothly, I'll probably have my friend help me install it as I've never
done one before and he has.

Thanks everybody!
