New KDC-135 has Power but Faceplate won't light up


you shold always twist the end of the wiring together and tape them never use connectors, remove the connectors and twist the wires driectly to each other and tape them wiht electrical tape, the connectors almost always can not deliver the proper voltage..

Did you make sure you have the yellow to a constant connect wire and the red to a turn on?if not this can cause the radio not to work......

you can test wich is wich by turning the key off and putting the yellow to the one you think it is and red to the one you think it is, if you have have it right you will hear the CD player make a click run sound...... if not you will not hear any thing.

car stereo help


There are some tests you can perform for checking the stereo. Yes, you are right, there is a yellow and red wire. Yellow constant power, red is switched throught the ignition. During the installation, you may have blown a fuse. A bigger fuse is not needed, stick with the same size if you find a bad fuse. Hook the red and yellow wire together for TESTING PURPOSES to one or the other of the hot wires in the vehicle. This will also test to see if you have a bad fuse. If the stereo powers up in one or the other power connections in the car and works, you have a blown fuse. I have seen some fuses be located under the hood of the car near the car battery. Hope this helps, Bob

re sent wire diagram gat all messed up


Hi
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

How to test unit without hooking up to vehicle.


You can connect the + and - from the stereo to a 12 volt DC power supply, or a step down transformer to test out the functionality.

This one is 20.00 bucks at Radio Shack.8f95084.jpg

Best of Luck.

How to install?What wires hook up to where?


Hi, Re the power wires - black is ground (or - of battery), red goes to the + terminal of the battery and the yellow would go to the Acc in the ignition switch of a car. If you are hooking it up on a spare "battery", you have to twist together the red and yellow and connect both to the + terminal. Good luck and kind regards.
