Western digital lap top drive does not seem to spin at start up 160 gb



Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical extension or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly


motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working


also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in


hope this helps you

Water starts to spray from the bottom of my Bosch Aquatak 120i when i turn the water on. Is it still safe to use when this is happening


Electricity and water can be a hazard which could be life threatening, but you can operate electrical equipment in a wet environment if you are careful and follow safety precautions. Most import, make sure the electrical outlet you are using for the pressure washer has a working ground plug. Just because an outlet has three prongs does not mean the ground is working. You need to use an outlet tester which is inexpensive from a hardware store or use a multi meter to test the ground for conductivity to earth ground. Your power washer should have a working GFI (Ground fault interrupter), and you need to press the test button to make sure it is working. If your power washer does not have a GFI purchase one from a hardware store. I would also plug the power washer directly into the electrical outlet since an extension cord could have a bad ground connection and will cause the power washer to pull more current from the outlet. Make sure the power washer is raised of the ground so it will not sit in a pool of water. If you follow the safety precautions you should be safe but keep in mind water does not carry the electrical current, it is the impurities in the water which carry the current. Therefore, water could be more conductive depending on the impurity of water. However, it sounds like a loose connection in the power washer which could also be an o-ring or a washer is broken and it would b a good idea to have it fixed.

WHAT IS RESISTANCE WELDING?


Electric resistance welding (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electical reistance of material vs the time and the force used to hold the materials together during welding. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the coating or the lack of coating, the electrode materials, electrode geometry, electrode pressing force, weld current and weld time. Small pools of molten metal are formed at the point of most electrical resistance (the connecting surfaces) as a high current (100-100,000 A) is passed through the metal. In general, resistance welding methods are efficient and cause little pollution, but their applications are limited to relatively thin materials and the equipment cost can be high. although in production situations the cost per weld may be as low as $.04 usd per weld depending on application and manufacturing rate.

Does this washer dryer need to have a ground fault plug in?


Hi!!
No, the washer/dryer does not need a GFI, it is well insulated an all electrical components that even if you had a water leak, and touch the unit, it will not shock you. What is needed is a 3 prong connector, this extra ground prong will increase the protection against a electrical shock. I have seen people that removes this prong so they can use an extension cord, it is not recommended to use extension cords with this units, but in case that you must use one, make sure the extension cord has 3 wires and an AWG rating larger than the load is going to carry to prevent overheating and possible fire hazard.
Most homes are equipped with a dedicated outlet for the washer/dryer. If your unit is connected to one of those outlets, you have nothing to worry about.
Good Day!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Miller S-54D 115V digital wire feeder that does not weld right.


Hi Kevin,
Causes of poor penetration: Travel speed too fast, welding current too low,
poor joint design / and or preparation, electrode diameter too large,
wrong type of electrode, excessively long arc length.
Solutions: Decrease travel speed, increase welding current, increase root
opening or decrease rootface, use smaller electrode, use electrode with deeper
penetration characteristics, reduce arc length.

Phillips dvr won't power up. Lost power at house


Try hooking it up to another (working) electrical outlet. If that doesn't work, there's several possible problems.

The most likely is that the box was fried when a larger-than-usual current traveled down the line (or even down the coax if lightning struck and your system isn't adequately grounded); the electrical outlet is either pushing too much or too little power; or your house's ground polarity is reversed.

More than likely your box is bad. If you don't know very much about electrical systems, don't go messing with your ground or any outlets without a wall plate.

Electrical current problem with the fuel pump


Then you have a ground problem. that is the only thing that will keep current from traveling through the pump is that it is not grounded.

Ground lead arcs when I connect, and auto idle kicks up


Hi
what are you connecting the ground lead to?

Is the welding machine phisicaly in contact to what you are welding ?

Can you electrically insulate the welding machine from everything, say stand it on a sheet of timber?

Regards
Rob
