    Your details are too sparse to do anything with; the message doesn't make sense.


    What DC voltage are you measuring and where?

Optoisolator is probably bad, horizontal out is bad also, check a transistor c3138 and change also

Will a Packard bell i media desktop run on united states power ?or is it strictly designed to run on European power ?


Here in the US, and with more than 20 years experience as a computer tech I would venture to answer that almost any computer should work almost anywhere in the world.
You only need to look at the input voltage and make certain the power supply is set to match the line voltage supplied where you are. Standard electricity in Europe is 115v or 220v @ 50hz and in the US it is 115v (almost universally) or 220v (rarely) @ 60hz. The biggest difference is the ac frequency used but for computer power supplies that is immaterial.
A computer power supply converts the ac input power to regulated and filtered 3.3v, 5v, and 12v dc so the ac frequency does not have any affect on the filtered dc output that actually operates the computer. Almost all power supplies have a voltage selector switch near the power cord plug on the back of the computer to choose 115v or 220v. Newer power supplies are designed to be auto selecting on input voltage so even that manual selection is no longer required.

You likely will need a different power cord since the shape of the prongs on power outlets in Europe is always different than here in the US. If I remember correctly from my time in Europe that even varies by country there.

As long as you keep in mind the possible different voltages and the different prong shape and arrangements for the ac power source your packard bell computer should work well here in the US.

Absolute worst case scenario would be that if the power supply already installed in your PC is extremely low quality and was designed to use only one input voltage then it is possible you may need to replace the power supply with one that is designed to be used anywhere.

How do I use this adapter in the US with 220 voltage


is it an 220volt ac - dc adapter you could buy a 110V AC to DC adapter with the same DC Voltage and current rating
or you could buy a 110V to 220 Volt adapter

be careful with switch settings
http://www.ebay.com/bhp/transformer-110v-to-220v


please be aware if timing is required or electrical motors this could be a problem as usa is 60Hz and your appliciance may be designed to run at 50 Hz frequency
there are devices that can convert freq from 60hz to 50 hz

How to test the electrical system of the generator for free


Ez test to determine if stator wiring is ok. This test works on generators that have two sets of 115v plugs and 220v plug. Use a 12v, 1amp ac power supply ( smaller ac power supply should work ok ). With generator not running, apply 12v to one of the 115v outlet plugs. Now verify 12v output voltage with meter at another 115v outlet on generator. Also verify that there is about twice the voltage at the 220 v outlet plug (should be about 20v - 24v) . If the adjoining 115 v outlet plug has no output or very little voltage or if the 220 volt plug has no output, most likely stator is damaged or breaker is off. If the stator is shorted voltage reading will be very low and power supply will heat up. If stator is open, there will be no voltage at second 115v plug or 220 v plug. If voltage is ok at the other outlet plugs as per test above then most likely problem is with voltage regulator, or brushes not making contact or armature winding open or just needs to be energized. Unplug the 12v power supply after test to prevent it from overheating. Most generators have two 115v windings that together power the 220v plug. When you energize one of the windings with the 12v power supply, the second 115v winding will be energized also and give you a voltage reading about equal to 12v. You will not damage the generator with this small voltage being input thru the plug. Good luck

How to wire motor sta rite p2ra5e 181L


The green wire is the ground and bolts onto the motor frame on the top part,(should see a green screw). the other two wires go to the two posts with screws to clamp down on the wires. It does not matter which way these two are hooked up, one on each post.


Most motors are pre-wired for 220v from the factory. If you have 220v you're good to go. If you happen to have a 115v setup the motor will run at half speed. The motor can be converted to 115v by moving a brown wire and a white wire in the motor. The diagram is on the motor label.Best to verify your voltage first.

Can you run 110v from a 115v geni*tools)


I'm a little confused about what 'geni' is.

The outlets in your home are rated at 120v AC and any equipment that you plug into them that state 110v or 115v will work fine.

If you are referring to some type of adapter that you plug into a wall and then into some electronic unit, be careful. It isn't just the voltage that you should be concerned with but the amperage!

Adapters generally take the AC current from a wall outlet and then convert it into DC voltage. This voltage is more or less specific to each device that requires DC input. As a basic rule, you must match the exact VDC and mA from your device with the same values on an adapter.

I have a 5700 11 horse, (brushless). the windinds appear to be good,none burnt or open, but I have no output voltage. Any ideas?


Some generators have a wiring harness plug. Unplug harness and test for output there. If no output at harness, look for open circuit breakers and test any capacitors in system wiring. Some brushless systems use capacitors to excite armature. If diodes in armature are faulty there will be no output. Generators output two circuits of 115v each when combined will be about 220. If your generator has two 115v plugs each plug will be on a seperate circuit. To verify condition of stator windings, apply low ac voltage (8 - 12v ac less than one amp) to one of the 115v plugs and you should be able to read same voltage on second plug and double the voltage on the 220v plug. Good luck

10,000 watt generator 220 plug doesn't work


Most generators have several circuits incorporated within the windings. There are usually two 115v windings, one or two windings that produce power and sensing voltage for the regulator that supplies power to the armature (produces magnetic force) and sometimes a 12v winding to supply power to charge the battery. The two 115v windings power one 115v plug each and together power the 220v plug. Each outlet has a breaker and or ground fault. Since the 115v plugs are working indicates that the 220v plug must have an open/broken wire or faulty breaker. Easy to check, however you must open cover to wiring compartment and trace wires. Should be easy fix. You do not have to start engine to find broken wire. Use ohm meter instead. With engine off, Insert probes into 115v plug and obtain ohm reading. Then insert probes into second 115v plug and obtain similar reading. Look for same reading at the 220v plug (remember 2 circuits of 115v, ground and neutral). Good luck with your repair and email if you have other question.

Power Issues or Drive Issues??


First and foremost, check to see that your turntable is set to the correct voltage setting for your area.

Remove your slipmat, as well as any rubber mat you might have on the unit. You want to expose the metal turntable platter. On the platter you'll see 2 holes on opposite ends. Rotate the platter to the 9 o'clock position. You'll see a voltage switch - 115V / 220V - make sure it's set to your country's setting:

U.S. / Japan / Canada: 110-115V
EUROPE: 220V

IF, you do not see this option on your turntable, then you do not have a Dual Voltage turntable. Now your talking about damage to the drive system. Which is comprised of various circuits, of which anyone of them could be bad. At this point, you'll have to take it to a reputable service center to have it diagnosed.
