You should be able to use the 3 conductor plug with no problem. It actually would be better (safer) if you did use it. Someone may have removed the ground because they had old outlets with only 2 slots.

The computer must have a three prong plug for safety of the equipment and yourself. Never remove the earh pin as you call it. There are adapters available at any hardware store if you only have two prong receptacles. Steve

I have a 2002 Chrysler Voyager that won't turn on even after replacing the gas filter, gas pump, and spark plugs. Do you know if anything else that is preventing it from turning on?


Immobilizer? Its likely to be the 21 pin plug behind the heater control panel. Remove the long plastic strip under the control panel (prise of gently, held on by 2 clips) remove 2 screws behind this and 2 screws above on panel. The whole lot should easily come away. There will be 3 plugs, remove all three and try to start the car. If it starts your problem would be the earth. Hope it helps

Ive got these speakers and a real high pitch noice just started coming out of them


hello, This can due to loose connection in the stereo cable (broken wire). and also do you have earth wired to the system or the output device? This is how to check a broken wire, just simply remove the stereo jack coming from you device or PC. make sure you remove both ends, see whether the sound is gone. if you don't have a earth wired, please use a proper three pin plug. if this doesn't work, you have problem with the sound amplifier inside the sub-woofer.. you need a repair :(

I want to know the international colour codes for wiring a three pin plug please


The colours vary from country to country.
In the UK and Ireland the colours are
Brown = Live, (Goes to the pin connected to the fuse, on the right if the longer, earth, pin uppermost)
Blue = Neutral (Goes to the pin on left if longer, earth, pin is uppermost)
Green and Yellow = Earth (Goes to the longer pin)

In the USA and Canada
Black = Hot (Goes to the pin on right when the long round,earth, pin is nearest the floor)
White = Return and (Goes to the pin on Left when the round, earth, pin is nearest the floor)
Green = Earth (Goes to the longer round pin)

How would you fix an onboard video card


Basically there are 3 possibilities for on board video card failure
1.Hardware,
2.Software and
3.BIOS control

To fix the problem please follow the below steps
1.First of all unplug the power cord to avoid any shocks
2.First reset C MOS , to reset C MOS. Remove the case side panel and using the instructions provided in the motherboard manual, locate the three jumpers used to clear C MOS. Your motherboard will have a jumper shorting two pins usually labeled normal operation. Remove jumper shorting pins one and two, and replace that same jumper on pins two and three

4.Then plug the power and

Your system will not power up. Remove the Clear C MOS jumper from pins two and three, and replace it on pins one and two. Power up System. The system will require you to enter setup and correct the default settings. If clearing C MOS had no effect, you will not see anything on your screen when you power is back up.

If the above did not work then proceed further,


Enter setup, fix the date and time, and you should be in good shape, as most newer computer systems will automatically detect the rest of your setting.
While software driver errors can be fixed, this is something that can only be dealt with if you have some form of video function. If the screen is black, try clearing C MOS, as described above, and otherwise proceed to the next step.

Now the last step is to replace the video card.

Thanks.
Have great day.

Replaced switch but circuit breaker trips on start up ! Mowermm600


Your circuit breaker will trip because of two main reasons:
  • Electrical power point circuit is overloaded (too many appliances active on the same power point circuit)
  • Power Lawn mower has become unsafe as your active live is able to reach your earth connection (e.g. short-circuit). Make sure that you have correctly reconnect ALL your power leads wires (check that the Active and Neutral wires have not been transpose). With power off/device unplug, use a multimeter on resistance range and verify that your active lead pin is not showing a reading against the Earth (middle) pin when the mower switch is turn on or off! There should not be any resistance reading between the Earth and Neutral (opposite pin to Active) pins either!
Hope it helps.

How do I replace a power supply on a Compaq Presario SR5110NX Desktop PC


you can purchase a power supply from any computer store *********** board supports both standard IDE and Serial ATA connections, so you want a power supply that does SATA power as well. Unplug the power cord from the back of the computer. remove the cover from the case and verify that there is no green LED on the board that is lit up (if there is, there is still power on the board). unplug all connections from the current power supply, including all drive power and the large 24pin plug (actually a 4 pin plug that is combined with a 20 pin plug) on the board, then unplug the 4 pin plug near the processor. careful that the 24 pin plug and the additional 4 pin plug near the processor have latches on the side. Remove the 4 screws that hold the power supply in and remove the power supply, install new supply and reinstall the 4 screws. first plug in the 4 pin plug that connects with the 20 pin, the 4 pin plug has no latch, it is held in place by the 20 pin plug. then plug in the 20 pin plug and the 4 pin next to the processor. then plug in the drive power to all of the drives. Install the power plug at the back of the system and you should see a green LED on the board when you insert the power. replace the cover and power the system up.

I have a heater that can work on 3 phase or monophase. I know because there is a screw that can be turned to switch between the two. The problem is that it has been wired for 3 phase with 4 wires: earth,...


2 x black go to each leg of 230 power. Neutral goes to a neutral point, and earth goes to an earth ground point. While you can tie earth and neutral together (they are in the breaker panel anyway) it does not meet some codes to do this when the appliance provides for separate connections.
