I need to know the voltage of Mutsumi D359M3D floppy and where?

Really need to know what equipment you're having trouble with. Provide make and model and info on power source (battery, DC power supply...)
In general though, if you can sample your input voltage near the unit with it still plugged in (use pointed probes or skin back wire insulation) and see what the voltage is with the unit turned on. If it drops when you turn it on, look for a bad connection in the line going to the source.

1. take out from supply ,by take out power cord from outlet
2 reconnect power suplly and switch on,manually if needed, and then do hard reset,as is written in factory manual ( turn back to factory settings)
3 if that not help ,disconnect last connected device,or all and try again
4 check one more time power line voltage on outlet, , voltage selector on back plate on device, and for test purpose only connect ur AV Receiver plug directlly to outlet,without any extension cords with other outlets or devices on them ,as that can be source of problem ,too.(power,or voltage drop bellow point that is needed for this power drawing device to be switched on)
5 also disconnect for test purpose dig coax,and or antenna inputs..best is to disconnect all,and connect in directlly to power line outlet,and then to try hard reset to factory settings.

You need to trace the power source, and not only the relay. Check the voltage of cable/contact points of relay while your turn on ignition. If you don't have a voltage tester, you can use the bulb to verify the presence of power.

When everything does'nt work the problem is usually esier to solve..it implies a faulty power source.

The fault may lie internal or external to machine. To rule out external machine fault try to use some other appliance on the same plug point if it works we know the probles lies within the machine.

If the problem lies within the machine, unplug power source and open the machine.determine where the power cable terminates within the machine. We are now going to check for breakages in the powe cable (that connect the machine to power source) You will require a multimeter. With the multimeter placed on continuity mode check for continuity between the plug point and internal terminating point, you need to perform the continuity test for both live and neutral in unplugged mode.

Next if the fault is ruled out in the cable the fault most certainly lies in the SMPS to check this we need to take a few precautions and carefully observe the power input and output points on the washing machines SMPS (Switch Mode PowerSupply) older machines use a transformer but it all boils down to correctly determining the input and output terminals.

Now with the multimeter in Volt meter mode(AC), carfully power the machine through AC Mains, ensure that the ground and machine are not damp (wet) without having physical contact with the machine you need to test the voltage across the input terminals (this should read around 110 to 220 (AC)Volts depending on the standards of your country) then check the voltage off the input terminals this should read between 20 and 80 Volts DC.

In most cases with your typical problem mentioned you will fail to receive an output voltage at this stage and can conclude that the SMPS is faulty.

If the SMPS is faulty you'd simply have to change it , in some cases though these have detachable fuses which blow off. In the lastter case you can try a fuse rep[placement.
This should solve your problem.

the easyest way to do it is to open up the side panel of the computer rite down the info off the side of the power supply such as voltage and so on then go out and buy the same type then as you pull out a plug from the one in your computer put in the same plug from the one you bought and you should be rite, theres nothing that technical you need to no just disconnect it from the power and pull out the plugs its that easy

there are a few things to check out,< the outlet to unit needs to be tested for voltage on both sides, the power cord needs to be checked with a multi meter on ohm selection from end to end, the connection from power cord to power point,"junction", needs to be checked," looking at it you can tell if there is damage". If you find that everything is ok on power end then element is most likely problem. the power test is important because with 220 power source it is split into 110 for timer and motor and 110 for element operation, " if one side doesn't have voltage then it will not operate.

The 7 pin connector is for the media card readers and needs to be plugged into a USB header on your motherboard. Not all motherboards have this header, so consult your motherboard manual. You may have to connect it in place of front USB connectors on your PC case.

The card reader will work without a separate power connection. The power connection is for the floppy drive only, and IS required for the drive to work. You should be able to find the appropriate connector on your power supply.

You must have the yellow and the red wires tied together on a constant voltage source.

Only the yellow wire should be on a constant voltage source.

The red wire should only get voltage when the ignition is turned on or in the acc. position.

You need to rewire the red wire on the radio.

Let me know if it helps.

Am not familiar with the model but Compaq would be your best source...support and downloads....if not, and you will need to poke around.....there is an absolutely phenomenal free driver site in Russia that has (personal opinion) virtually every driver ever made in every version. All free. You can also try the add/remove hardware auto detect and point it to Microsoft...you might get lucky. The only other solution is to query the internet with your model number and the words driver behind it. Hope this helps....Tango.
