Yellow Wire has no power

The yellow wire is the memory wire and it has no power. I hooked the red and yellow wire to the red wire from car and my stereo works. But in order to save my settings when I turn off the car I need the yellow wire. Does anyone know what fuse makes the yellow wire active.

    My stock Radio was not installed when I bought the car. I had a friend take out my old stereo so that he could have it. The yellow wire was hooked up to the yellow wire on aftermarket stereo before. I'm not sure if a fuse is broken or a wire got pulled out. There is only one live wire and that is when the car is on. The yellow wire does nothing and I have no free wires except for the sub wires. I was told there was a fuse that is should be used for the yellow wire but im not sure which. If I do run a new wire, how do i get it from my battery to my radio.

Your stock radio should have had a wire that does this. It may not be yellow so look up the wiring diagrams for your car. If you can't find it by doing that, then look up a diagram of your use box. Sometimes there's a diagram on the back of the fuse panel cover or somewhere around there that tells you what fuses are from what. You can then run a new wire if you have to.

    Ok... The good news is that you do have the ignition switched wire
    working properly. That's the complicated one. You should first try to
    run a new wire from the fuse box. Look toward the back of the box and
    figure out which fuse is for the radio. You might even see the other
    end of the missing yellow wire if it got cut off or broken or
    something. Then you can use that. If not, you'll have to run another
    wire directly from the + terminal of the battery itself. You will have to find a place to run it through your firewall (look for the spot where all the other wires go from the engine bay into the cabin) and use that. And you should use an inline fuse on this wire if your deck doesn't have a fuse built in.

The diagram is not right my CD player will not turn on unless the red and yellow hooks up too the green wire

The Red and Yellow must both provide power.
Red to ACC ignition and the yellow to permanent battery power to retain station memory.
So look for 2 power sources.

Where do you connect the memory wire on a jvc kd g110 car stero.....what color is the memory wire ?? what does hook red wire to acc fuse mean??? what wire does the red wire on the radio connect to on...

The yellow wire is most likely the memory wire as it needs to be connected to a constant 12 volt source.

"Hook red wire to to acc fuse" means you need to hook into the fuse block under an Accessory Fuse. (ie: something that can't be turned on unless the car is running or the key is in the "Accessory" position)

The red wire is explained above. It does not connect to the harness.

Just remember that the yellow wire needs to be hooked to a constant 12 volts and the red needs to be hooked to a circuit that is only active when the car is running or switched to the "ACC" position.

My memory wire is yellow & my power wir is red. I have them all hooked together so that the stereo will turn on. My kenwood cd player will not hold memory. Can you help??

The red wire goes to the ignition 12 volt source, and the yellow to the battery 12 volt source. The yellow wire must remain hot with the key out to retain memory.

I am hooking up the stereo and I know I have power coming to the wires cause the black and yellow ones spark but when I hook them to the stereo I don't get any power

The yellow wire is the constant wire, you need to find the battery + wire which will be red and hooked that to your deck, the red wire is the main 12v wire and the yellow wire is there just to use a little bit of power to keep the memory i yur deck, i.e. the time, cd position stuff like that

I have an after market pioneer car stereo and not sure how to hook the red,yellow and blue with the stripe, to the wire harness with orange lummination and orange dimmer negative,yellow batt. and blue i...

red is usually ignition switched power from the fuse box and the yellow is continuous power to the deck. blue with the stripe is usually a voltage output from the deck to control the on/off of an external amplifier. If you hook the deck up and the memory stations do not save after vehicle on/off cycle of the ignition swap the yellow and the red wire and they should work. One is power all the time to allow the deck to store memory and the other is the main power to the unit.

I install a radio it dont keep a memory

Pull the radio back out. I bet you hooked up both power wires (red and orange or yellow) to the ignition on hot wire. Orange or yellow depending on the radio usualy goes to the ignition on hot wire and red to a constant hot wire. Check the radio wiring diagram or list. One of the power wires has to go to a full time power source. check the wires with a circuit tester with the key off till you find the constant hot wire (battery power)

As long as you have connected the ground(black) try adding one wire at a time to the live(red). If possible try connection each wire one at a time to the power line and then both together. If nothing has blown(fuses) and the unit starts working then you can try by trial & error method the remaining wires. You should be able to figure out which wire is required and if there are any extra wires like cellular phone(mute) and then decide whether to connect them or keep them open.....sodeep

Re sent wire diagram gat all messed up

have we spoke before in previous post?
the red can go to any 12v live peramanent such as wire to clock or other item that has power with ignition off and the same with the yellow if your putting these to the same permanent live say from clock you can join these to together red/yellow to red on clock
the black can go to any metal or neg wire.
This should then have your device working the only problem im looking at for you now is the pink wire as this stops you using the device whilst driving as it goes to handbrake but i need to find out if its live or negative.
You could just wire the red/yellow to live and black to earth then see if it switches on and works if not then let me know and ill see about the pink wire ok
Makes sure you use inline fuses on the live wires so as not to short the device out.
Make sure you know what is permanent live to put the yellow/red wire to.
It doesnt need to be ignition it only says this so you cant use it with ignition off but you can wire it into any live feed from clock or switches so its up to you what to wire it to its just the pink wire im concerned about.

PINK: does it tell you to put it to live or earth on handbrake switch?

let me know ok
