The answers were a little helpful on the 4 wires.but the 1 i have has 5 wires.

Black = AC hot
Red = switched AC hot
Yellow = AC hot from a another source - another control panel as an example.
White = neutral
red w/white tracer = switched neutral
Green or green w/ yellow tracer = ground/earth ground
blue = DC voltage, ie, 12vdc, 24vdc
white w/blue tracer = dc common
Brown = AC 3 pahse - phase A
Orange = AC 3 pahse - phase B
Yellow = AC 3 Phase - phase C
shileds: think of current loops
2 cond
clear or red = +
black = -(neg)
3 cond
red = power (24vdc typically for transducers)
clear = + (signal output)
black = - (signal common)
Hope this helps, oh, and any panel I have design and wired this way is easily understaood by 99% of all service and electrical people I have worked with.

The AC adaptor goes into the AC socket, NOT the computer connection. The Computer connection is DC and comes from the DC side of the Adaptor. If you mean the DC socket has broken, then you need someone to replace it inside the computer.
If the AC adaptor has failed, you can buy a replacement ( 19V 3.16A 60W AC Adapter).

Casio AD-12 for my country with 240V

You may use any 12V 1A AC Adaptor that has the same DC jack provided the center is NEGATIVE. Most common generic AC Adaptors are Centre POSITIVE.
So cut DC end of the wire and solder them in reverse and insulate with tape and it will work.

Brian, first of all, make sure you have a multimeter and let's agree on one thing: any wire that has a switched voltage or a voltage to control antenna or motor has to be DC type of voltage, right? The other ones for the speakers are AC voltages as in music, right? Therefore, I would go with a meter between the wire and ground and measure on the DC scale and turn the radio on. Keep an eye on the meter and you will see that if the voltage appears, it is a DC voltage and it will answer your question. Hope it helps.

THIS DEPENDS ON WHETHER YOUR RECTIFIER HAS 5/ OR 7 WIRES, SIMPLE ENOUGH THOUGH , YOU WILL SEE THREE YELLOW WIRES THESE WILL COME FROM THE AC SIDE OF THE GENERATOR ON THE ENGINE TO THE RECTIFIER, IT IS HERE THE AC, ALTERNATING CURRENT IS CHANGED TO DIRECT CURRENT DC IS USED FOR STARTING THE BIKE, AND PROVIDING POWER FOR LIGHTS ETC, YOU WILL THEN FIND 1 OR 2 GREENS, GREEN IS THE BIKES EARTH ON OLDER HONDAS, SO PUT THESE WIRES TO A GOOD EARTHING POINT ON THE BIKE OR WIRE INTO THE LOOM , YOU WILL TEN FIND 1 OR 2 REDS, AS RED IS THE DC OUTPUT FROM THE RECTIFIER YOU WILL NEED TO CONNECT THIS TO THE POSOTIVE+SIDE OF THE BATTERY

I would use 10 gauge wire for it. It will be a little overkill also but you will be safe that way.also to let you know the smaller the # for wire the thicker it is. Yes Green is ground.

Unplug the battery from the laptop and then plug the AC adaptor into the laptop. If the green light still goes off then your motherboard is shorting out the adaptor and the motherboard needs to be replaced.

The green wires go to the left channel (Plug tip). The red wires go to the right channel (plug ring 2 band from tip) and the brass wires go to the ground (sleeve plug base).

It is tough to find the right power adaptor with the "right" length cord. Your best bet would be to use an electrical extention cord for the added length you need. "if you can't get the adaptor to the outlet....... take the outlet to the adaptor' !!!!

Arunk, When you say the electrical characteristics of the new A/C adaptor are the same as the old one did you check to ensure the amperage and the polarity of the power plug is the same as well?
