A higher voltage means more drilling power but it can also mean more weight - don't buy a drill you won't need, 12 volt drills are powerful enough for most home users, bigger models just weigh more so think carefully about what you will be using the drill for.

I might add that the new dewalt drill that uses the new nano (lithium ion) batteries weigh less than their nicad counterparts. They also do not develop memory that shortens the life of nicad batteries.

Battery not charging gx670


The voltage regulator may be bad, will need to unplug magneto and use multi meter and test magneto for voltage output on milliamp scale with the engine cranking, If voltage is present when cranking then the voltage regulator is bad , if no voltage then the pick-up coil and stator will need to be replaced.

Mains voltage in Australia is 230V 50Hz. Travellers from most nations in Asia, Africa and Europe should have appliances that work on the same mains voltage as Australia - therefore you will not need a voltage converter. Notable exceptions to this are Japan, USA and Canada which uses 100/120V 50/60Hz.
If your country does not use appliances within the 230V 50Hz mains voltage range, you will need to purchase a voltage converter. This will transform the voltage from the power outlet into one your appliance can use. You will also need a power adapter.

UPS does not supply power under 150~ volts


UPS will provide constant voltage out put.
The average working condition of UPS is 170 to 270 volt.
Below the level may not work.

Yukon 2.5 x50 nvrs tactical night vision rifle scope, works fine but making a strange processing noise when on?


Hello, don't worry about it. It is HV to the image intensifier tube. The battery voltage goes through control circuit then to ccfl inverter (here is were dc voltage is switch on and off and switch dc voltage is step up by toroid coil that has two input and only two out puts). By impulsing the coil with two different switch dc voltage on the input this make the current lag the two different phase voltage by 90 degrees. Here is where the strange noise is coming from. The toroid coil is encased in iron case and if half of this iron case is loose, it makes case vibrate so the noise.


Now, the voltage come out of the toroid coil is switching dc (one could call it AC because that what AC voltage is, it switch between positive to negative) this voltage is about 300 to 900 switching DC voltage. This voltage will be applied to a 1/2 wave voltage multiplier (this voltage multiplier with have anywhere four four stages to 10 stages depend on what the input voltage to multiplier is.

Low the voltage out of the ccfl inverter the more stages the multiplier will have.



Now, the voltage multiplier will double the voltage per stage to need image intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever one wants to call it. This voltage will bit you but it doesn't have a lot current associated with it, the current would be in the 10 to 15 ua (micro-amps) 1/10X6 amps.

There is a ground some were that is causeing the battery not to charge put new selinoid ,new battery,alternater,new key lock cylender check wirers fuses relay switches and battery still wont charge


It sounds like you have done a whole lot of replacing and not much "diagnosing". Did you chech for battery voltage at the alternator? There should be battey voltage at the large Black/Orange wire that is on the B+ terminal of the alternator. This wire should have voltage all the time. If there is no battery voltage, you most likely have a burned fusible link at the starter relay area.
There should also be voltage at the "S" terminal with the ignition on. If there is no voltage, then check for voltage at the "S" terminal of the voltage regulator. If there is no voltage at the "S" terminal on the voltage regulator then check the "I" terminal on the regulator for voltage.

NOTE: The voltage on the "S" terminal should be 1/2 that of the voltage on the "I" terminal.

If there is voltage on the "I" terminal, make sure your voltage regulator is grounded properly to the fender and retest to see if it is charging the battery. If it is still not charging, disconnect the regulator connector and connect a jumper between the "A" and "F" terminals of the connector. Start the engine. The alternator should now be charging the battery at high voltage (usually over 15 volts) If it does, replace your voltage regulator. If it does not, then you need to check your wiring between the voltage regulator and the alternator.

No deisel getting through so will not give hot water


The fuel solenoid is controlled by two switches, the flow switch or pressure switch and the thermostat or snap switch. These switches are wired in series which makes them relatively easy to test.

First pull the electromagnet off the fuel solenoid valve on the fuel pump hooked to the side of the burner. Slide a screwdriver inside of the magnet and turn on the burner. It should magnetize. If it doesn't you need to pull the electromagnet from the wire it is hooked to and test for voltage. The voltage will be either 12V-24V, 110V or 220V depending on the solenoid you have. It will tell you what voltage it should be on the side of the solenoid. If you have voltage you need to replace the electromagnet. If you do not you will need to follow the wires back into the electrical box.

The next switch you will test is the snap switch or thermostat. It is wired in series to the solenoid wires. If you have a thermostat test for voltage on the outgoing side. If you have voltage the wiring to the solenoid is bad. If you don't have voltage, test for voltage on the incoming line to the thermostat. If you have voltage your thermostat is bad. If not you need to test the flow switch. The process is the same if you have a snap switch however instead of testing the terminals you will test each wire going into the switch for voltage.

Next you will test the flow switch. First test for voltage coming out of the reed switch on the flow switch. If you have voltage your wiring to the thermostat is bad. If you do not have voltage then test the incoming side of the flow switch. If you have voltage your reed switch and or flow switch are bad. If you don't you will need to test your main power switch as the problem lies in the system sending voltage to the burner circuit.

This is a complete test of the burner circuit and should help you isolate your problem. If it doesn't feel free to contact me at 800.247.8103 and I will help you trouble shoot further.

Put new battery in car and it wont even try to turn over. Is it the starter?


Check voltage at starter, there's a big wire and a small one, the big wire should have voltage all the time, the small one will only have voltage when key is at start, with test light check voltage at big wire, if no voltage check battery terminal's, if there is voltage then check voltage at small wire while some one hold's ignition key to start if you have voltage bad starter, also hit starter while key is at start some time's it will crank engine over, but you'll need to replace starter, if no voltage check ignition switch, good luck, hope this was very helpful.

No, the AGP bus voltage cannot be changed. The AGP voltage is set from the facotry, and if you want a different AGP voltage, you'll need to get a different motherboard.

The Voltage refered to is the Arc Voltage not the input voltage, for dip transfer the arc voltage needs to be 18-20v for spray transfer try 25-38volts both depending an the WFS setting. arc voltage is set on the voltage control dial. lets know how this turns out.#

Converting ac to dc voltage


You need to transform the voltage to a level that you require, then 'rectify' your voltage to DC, with a bridge rectifier. There are many different types of rectifiers for different uses. Look on the web for electronics, bridge rectifiers.
