You cannot unless you have a switchable unit and most are not. You will need to use a transformer on the power cable to hook a 110v unit into 240 volt mains power.

2004 f350 6.0 liter Installing new Control Panelfor air spring/shocks. Needto tie into dashboard illumination circuit. what color is the dashboard illumination circuit wire? where would I find it?

The brown wire at the main light switch is what feeds power to the microprocessor in the main light switch and the exterior lights circuit. The microprocessor delivers power to the interior instrument and dash lights on the light blue with red wire again at the main lights switch. This circuit is dimable so if you need 12 volts all the time this may not be the right circuit to use.

I need to change my power supply from 110 volt to 230 volts on my ASUS model A-45GA and can't find a switch

Must not be a switchable power supply then. You will have to exchange for one that is switchable. Not all p/s have dual voltage capabilities.

My car radio is not switching on.the name of my car radio is a sony xr ca440x

For the most part, all car stereos, including the Sony XPLOD car stereo will have the same basic wiring with the exception of some additions for connecting to after market amplifiers. They all have a wire for the memory which is continuous power and one for main switchable power. There will be one main ground and a speaker ground. The rest of the wires are for the speakers. These are usually paired as the same color except the wire with the black stripe is the speaker ground. The easiest way to hook up a new radio is to get a pigtail harness for the Sony XPLOD from any store that sells radios. This is a direct hook up simplifying installation. The pigtail has the proper connection to simply plug in to the original connector and the other end to the new radio.

Not sure what the wires colours are

We dont either. You need to post what you are trying to connect. Amplifier? Sub? Speakers? Head Unit im sure. But you need to look for the radios wiring diagram.. Today's radios are generally basic with the color scheme. Black is ground. Red is switched power. Yellow is constant power. Orange if for dash illumination... Speakers are usually 4 colors. 2 wires a speaker. For instance Front Left would be White/Black-Stripe. White being the positive and black strip being the negative. Usually the four main colors for the speakers are White......Gray.......Purple..... Green... with the striped wires going to the negative on each speaker. Blue wires are usually for power antennaes or also used to send trigger signal to the amps to turn on and off.

What areall main causes of generator main stator burnt in sr4 &leroy somer alternators.

It can be many many factors, aside from the obvious (overloading) check the type of laods and the power factor of those loads, the gen alternator is rated at 0.8PF if your laod is a UPS without a switchable input filter, there is a good chance the unit is going into over excitation due to a leading PF. I have seen that before

I dont know what color wires are for what, i had my head unit stolen and now im not sure what wires go to the new kenwood head unit

The three main wires you need to worry about are the
Ground (Black) Battery + (Red) Constant + (Orange)
As far as the speaker wires goes you are going to have to trial and error them. They are usually color coded so for instance one wire is purple with a white stripe there would be a purple wire with a black stripe that would correspond with it. Every vehicle is different in how it is wired. I know installing a stereo looks intimidating but just split up the wires and you will see it is quite simple. Do a professional job and use crimp connectors, going the electrical tape route is never worth the time it saves.

Wiring colors

You will need a voltmeter. Normally red is power, black i ground, yellow is memory power. the best way to know for sure is to use a voltmeter to test what each wire is recieving in power and when. If the key is off then the wire that has 12volts dc is for memory and the main power wire should be at 0volts dc. When the key is on that wire should have power now. the ground will be black on that car. Good luck.
