Question about Car Audio & Video
Replaced a 6700mp.I hooked the yellow wire(battery) directly to battery,red wire to ACC and black(grd) to chassis and orange(ill) to yellow.stereo doesn't work.hooked orange to red(acc),stereo doesn't work,all other wires the same.red,yellow and orange together on ACC,stereo works(accidental experiment) now but will not keep preset stations,and it resets itself every time I turn the ignition on.have to search for stations.before I had yellow and orange together,red to ACC etc.the stereo will keep stations as long as the ignition is on but will loose them when I start engine again.I do not get it.any help will be greatly appreciated.so in a nut shell,everything works but I have to start over everytime I start the engine...thank you..steve
First red is ignition or acc (turns off and on with the key) yellow is constant power (always hot keeps memory) orange is illumination (lights up radio) if vehicle doesnt have a seperate illumination wire connect it to the ignition wire. now process of elimination your ground is correct because it worked with all wires to acc your acc works because u had all them connected to it and it worked your problem is in your yellow or constant/memory i suggest u test it again take piece of wire any old thing long enough will do and run the wire directly from the battery under the hood and just run it outside the car through the window and connect it directly to the yellow wire make sure u have a good connection at the battery on the positive side if u have test light or volt meter test the wire before connecting it to the radio if it works then u know there is a problem with the wire from the vehicle (fuse wrong wire bad wire ) if it doesnt work make sure ground is connected tight and that paint is cleaned of the surface where ground connects and that the yellow wire to the radio is tight in the back of the radio.
