I have an Hitachi VM E510A that has a 6 volt dc input but I can't find an end to fit it. What size is the cable end. I would order it if I knew the size

You are heading at this from the wrong end. The power to the device from the charger remains the same. If the device runs on 12 volts, it needs 12 volts.

South Africa runs on 230 volts, so if you bought a 110 volts version, you buy an adapter that takes 230 mains voltage in, and delivers 12 volts DC to the phone. The phone won't run on 6 volts.

230V South Africa operates on a 230V supply voltage and 50Hz.

Step1: At the end of your SecurityCam cable you will find three colored plugs: Yellow(Video RCA), white(Audio RCA),Black/Orange(DC Power) or identify
OR
Identify the cables at the end of the SecurityCam cable as color for video ,audio and power may vary.
Step2: Plug Video RCA plug(1) into the "Video In" input(3)(Usually located at the back of your TV or VCR)
Step3: Plug the audio RCA plug(2) into the "Audio In" input(4)(Usually located at the back of your TV or VCR)
Step4: Connect DC power plug(5) at the end of your Security Cam into the end of the power adaptor(6)
Step5: Plug the power adaptor(7) into the main power point in your wall
Step:6 If you have AV/TV with RCA sockets you will need to switch the TV to the AV change to view the camera.

Pictures is attached. Please have a look at it.

Possible suspects are:
1. A severely drained battery.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

If this is a battery powered CD player,
we are talking mA not amps.....6 x 1.5volt batteries give you 9 volts
I would recommend something like this:-

According to the specs for this welder

You need a 50 amp breaker and #6 wire

Century/Lincoln Inverter Arc 230 DC stick welder.

• 230 Volt stick welder compatible with optional TIG equipment. Welds 18ga to 5/16. Includes:
• 10 ft Work cable with small dins connector and clamp,
• 10 ft Electrode holder with small dins connector,
• shoulder strap for portability,
• 6-1/2 ft input cable with attached 50 Amp (NEMA 6-50P) plug

1) Power:

It may be the problem that occurs with a lot of USB powered devices jrherrer. Not enough power provided.

The USB cable plugged into the computer, provides signal wires for transferring information back, and forth, and also provides 5 Volts DC for power. (Two D cell flashlight batteries produce 3 Volts DC)

http://en.wikipedia.org/wiki/USB

[ Below shows the Signal pins, and the Voltage pins of the USB B Mini style connector, (Male), used to connect to the SimpleDrive Mini external harddrive,

Pin 1 is for the 5 Volts DC Positive (Wire color - Red)
Pin 2 is for the D- Signal (Wire color - White)
Pin 3 is for the D+ Signal (Wire color - Green)
Pin 4 is not connected. (Or sometimes joined to Pin 5 with a Resistor)
Pin 5 is for the Ground (Wire color - Black)

Just added info in case you wanted to know ]

From what I see the SDM/250RW has a USB port on the side, and a DC Power Jack, used for an AC adapter, also.
(Round port with a pin in the center)

From what I see stated from Hitachi, and sellers on the 'net, the AC adapter may not be provided.
Many of those who provide a review state that both the USB cable, and the AC adapter is needed to provide enough power. Seems to be a power hungry external harddrive

It's a 2.5 Hitachi SATA laptop harddrive inside that external case. (The Harddrive is 2 and a half inches across in Width. Common size used for laptops)

When using an external device powered by a USB cable there are general guidelines to follow,
A) The USB cable should not be more than 2 feet in length
B) Connect the device directly to your computer, instead of through a hub, or other device, unless the USB hub has it's own power.


2) USB cable:

Could be a faulty USB cable, although I imagine you have tried different ones by now.


3) Interface Circuit Board:

The Hitachi SATA 2.5 harddrive inside the SImpleDrive Mini SDM/250RW, plugs into a small circuit board located inside that external case.

Components on the circuit board may be fried, or the Harddrive may have come loose from the interface.

Loose from the interface
To explain;
The back of the harddrive has connector pins sticking out.
The interface has socket holes which the pins insert into.

Faulty circuit board
The external case of the SimpleDrive Mini SDM/250RW can be carefully opened up, and the Hitachi SATA 2.5 harddrive extracted out.

Another inexpensive external case for a 2.5 SATA harddrive can be procured, and the Hitachi harddrive put in it.

Example of a 2.5 SATA external enclosure,

One note is the power plug going into the radio appears to be atypical in polarity. The center appears to be negative ( - ) instead of positive ( + ).

please check the voltage of the battery may be the voltage of battery is low or use the multi meter and check DC volts before conneceting the battery and after conneceting once more check the DC volts it could slove the problem
the beeping sound is due to battery low voltage
what is the DC input of the Inverter check the battery hook up if the inverter is of example DC 24 volts please check what is the input

The Intec Gamecube screen requires both a 12 volt DC input and the AV input. The larger connection is the AV cable which plugs into the back of the Gamecube console. The smaller round cable is the 12 volt DC input cable that goes to the power source for your screen. The solution is to either get the original splitter cable that splits the DC power to the screen and the Gamecube, or use separate 12 v DC inputs for each device. These original Intec splitter cables are rare and are not cheap, and the only place I have found them for sale is at the NES Repair Shop:

The only other solution is having separate 12 v input cables for the screen and the Gamecube. And finding the right size (very small) is also a task.

Hello ndy3,

It can be because the wire inside the cable is at fault, but the main reason (99% of the time) is because the end or either the laptops power input OR the plug on the dc power cable is not fitting snug enough. This can be fixed by either getting a new dc power cable or by adding a drop (and i do mean drop) of gold or silver (or even solder) to the rim of the laptops input. But you MUST be VERY careful when doing this and make sure that whatever you apply is just coating it. If you do it right then the plug will fit more snug and the problem will be solved.

Hope this helps.
