2000 Camry Radio Wiring Problems - Toyota Nation Forum : Toyota Car and Truck Forums

AKARaccoon · 10-13-2010, 02:51 PM

Soo, yeah. I took out my Camry's radio in an attempt to install a new radio that had an auxiliary plug in it. I took out the radio, removed the "negative" wire off of the battery on the car, spliced all the wires together correctly, put the "negative" wire back onto the battery, and it worked!

Then, I picked up the radio and accidentally crossed two of the wires, which of course, shorted out a fuse in the fuse box.

I replaced the fuse, did the steps that I did above, and the radio doesn't want to turn on. I don't believe there's any power going through the cables that connect to the radio.

Would anyone have any insight as to how to fix this? It'd be epic, and greatly appreciated.

If you touched a power wire to the outside metal of your Radio you probably shorted something internal on the Radio itself which unless you have knowledge of radio internals I would just get another radio.

If you just crossed two wires without actually touching the radio, the first thing you could try to do is grab a test light or multimeter and confirm that you do not have voltage through your power wires. If you do have power I would suspect a shorted fuse on the radio itself.

The radio works fine. We already tested it by placing the red and yellow wires against the positive terminal while the black was against the red terminal. There was power to the radio, so we know that works.

What do I need to replace to get those "radio wires" that are coming -from- the car, to get power to them? It saddens me that I had it working, then I screwed it all up because I just didn't tape off the wires.

Did you see any smoke after it shorted out?

Is the new fuse you put in blown?

If the fuse is blown you probably melted a wire.

I didn't see any smoke.

The fuse was blown, yes, I replaced it.

Damn, how do I fix the wire? D: I have a feeling this isn't going to be easy, at all...

He was asking has the fuse blown again since? If so then you've got a problem. If not, check for other blown fuses. You probably just blew another fuse and didn't notice. I doubt you melted anything.

But since you've got the radio unhooked again, do it the right way this time and solder the wires and heat shrink them instead of "twist and tape". Tape falls off and then the wires come loose.

Don't make it sketchy.

The tape was going to be a temporary solution because I'm at school, and my soldering iron is at home as well as the solder.

I checked all the fuses earlier, and I don't believe I've blown one again since then, but I'll go check again. I'll assume that none others are currently blown.

Chris Crash · 10-13-2010, 04:48 PM

Did you check fuses under the hood too?

***LynchburgCSI*** · 10-13-2010, 05:09 PM

I really wouldn't do that as a temporary thing... but okay. I now travel with my soldering kit.

As everyone keeps saying, check the fuses again and report back.

AKARaccoon · 10-13-2010, 05:31 PM

Okay, I checked the fuses under the wheel, but I forgot to check the ones under the hood (I assume you mean the ones located directly to the right of the battery as if you're looking at the hood from the front of the car). None of the fuses were blown that were under the wheel...

I have a temporary "fix" on what I have. For some reason, the blue wire with the yellow stripe (I believe it's the "constant" wire, the one used for the "clock") doesn't seem to be working properly? Perhaps? The radio doesn't work at all when I connect the cars blue/yellow wire to the appropriate wire on the radio, and the "ignition" car wire to the appropriate wire on the radio, but the radio DOES work when I connect both radio wires to the "ignition" wire on the car...Is that a bad thing? Should I go un-wire it right now? Haha. Anyone know what's up with the blue/yellow wire from the car?

Also, I usually keep my soldering kit in my saddle-bags of my bike, that's why I didn't have it in my car!

***Mister_Perkins*** · 10-13-2010, 06:56 PM

sounds like you have a problem with your 12V Constant. You will just notice your radio will reset every time you turn your car back on and you will have to put ur pre-sets and time in stuff in every single time.

Sounds like you should have purchased a Harness adapter

***Mister_Perkins*** · 10-13-2010, 07:00 PM

Aftermarket CD player is

Red : Switched Voltage (Key)
Yellow : Constant Voltage (Battery - keeps your time and presets)
Black : Ground

As long as you have all three of these your head unit will work properly.

Are you sure that your fuse to your Clock isnt blown?

I really don't see shorting out a wire to completely screw up your entire wire. Thats why I keep asking you about the fuses. Normally the only time a wire will be junk if it is shorted is if it is connected directly to a battery with no inline fuse. The current will keep running through the wire, melting the wire and possibly causing a fire.

Vehicles are equipped with fuses. When a wire is intermittently shorted, that voltage is grounded immediately and depending on how many amps the fuse can handle it will be within a split second for the fuse to "pop".

As far as i can see from what you are saying your wiring is probably factory besides where you have spliced and taped the wires. Are you sure that the Head unit wire that you are talking about is the correct 12v constant wire?

Update : Just looked up the wiring for your camry and the blue/yellow wire is the correct wire. I keep thinking that you have a blown fuse???

Double check the fuse that is labeled "CIG" .. the CIG fuse is for the Radio also

I have no idea what a Harness adapter is. D:

Edit: Yeah, I had found a wiring color code chart online while I was doing it, it was very freakin' helpful, haha.

I'm pretty sure I checked all the fuses, but I have an extra fuse of every amp, so I'll just replace that CIG one anyway just to make sure.

This is a harness adapter

It hooks into your OEM radio harness. You solder / shrink rap your Radio wiring harness into this harness adapter, then simply hook it into your OEM harness plug, Hook up your antenna and then just re-install your dashboard parts. Makes life 1000000000 times easier

AKARaccoon · 10-13-2010, 09:21 PM

I don't understand...

But it's a little late for that! D:

...Or, is it?
