    Yellow Wire should be in plug connectors. Like Hard Drive power plugs yellow is already in the back of the plastic connector. Can you explain what you mean . Why is the yellow wire not where it is meant to be . ? Has it come out of the power supply circuit board ?

Use a needle such as a sewing needle, stick it into each wire, and use your voltmeter from there.

No need for color codes....

SOURCE: on my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.

The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

SOURCE: xtl head shows

Hello,

The red wire on the remote head should go to the battery (with a fuse inline) the yellow wire should go to a switched 12 volt source (with a fuse).
The XTL radio is in need of correct programing, With out looking at the codeplug I would say that the option for remote head was not checked.

Hope this helps, Bill

Which wire is the main hot for the power windows door switch 2003 Pontiac vibe

The main hot wire for the power window door switch on a 2003 Pontiac Vibe is the yellow wire. This wire carries 12 volts of power from the fuse box to the power window switch. When you press the power window switch, the switch sends a signal to the window motor, which causes the window to move up or down.
Here is a table of the wire colors for the power window door switch on a 2003 Pontiac Vibe:

Fault finding

Power is going to the motherboard, and you know this by assuming?

An assumption would be you see the Power Supply fan spin, LED lights light up, and maybe computer case fans spin.

Not an assumption, and you would have tested the 3 main voltage power rails, coming out of the Power Supply.

The Power Supply in your computer is an SMPS.
Switched-Mode Power Supply. (Also is known as the short abbreviation - PSU. Power Supply Unit)

http://en.wikipedia.org/wiki/Switched-mode_power_supply

The Power Supply in your computer is a Converter.
It converts HIGH AC voltage into 3 LOW DC voltages.

[Depending on country,
USA = 120 Volts AC. UK = 240 Volts AC. Japan is 100 Volts AC, but may depend on area. Australia = 240 Volts AC. India = 240 Volts AC. HOWEVER, do not write the above in stone. I may have made an error ]

The 3 low main DC Voltages coming out of the Power Supply is;
A) 3.3 Volts DC
B) 5 Volts DC
C) 12 Volts DC

Orange wires carry 3.3 Volts DC
Red wires carry 5 Volts DC
Yellow wires carry 12 Volts DC
ALL Black wires are Ground wires. They can also be called Negative wires.
This is a DC circuit now. There is a Positive, and a Negative.
Orange, Red, and Yellow wires are power wires, and also Positive wires.

The first part of your diagnosis will be to test those 3 main voltage power rails.

[Digressing;
Using an example;
There are many Red wires coming out of the Power Supply.
These are 5 Volt wires. They are Connected TO, the 5 Volt power rail in the Power Supply.
ALL 5 Volt wires end in one place, in the Power Supply.
The 5 Volt power rail.
When you test just ONE red wire, you are testing the entire 5 Volt power rail coming from the Power Supply.

This also goes for the Orange wires, and Yellow wires ]

With the Red 5 Volt wires, and Yellow 12 Volt wires, you could just use a 4-pin Peripheral power cable to check them,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Multimeter set to DC Voltage, the red (Positive) probe lead of the multimeter; touches the female metal terminal connector, for the Red wire.

http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction?t=2&utm_expid=8634549-14

The black (Negative) probe lead of the multimeter, touches a female metal terminal connector, that goes to a Black wire.

You should be reading 5 Volts DC.

Same thing for the Yellow 12 Volt wire.

With an Orange 3.3 Volt wire, this changes.
A straightened out paperclip is inserted, down into the BACK of the ATX main power cable's connector; AND into a socket hole with an Orange wire in it.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The straightened out paperclip, slides down into the socket hole, with the Orange wire in it.
Slides down into the socket hole, RIGHT NEXT TO the orange insulation of the wire, and MUST go down far enough; to Touch that female metal terminal connector.

EVERY wire going down into the ATX main power cable's connector, ends in a female metal terminal connector.

Same thing is down with a socket hole that has a Black wire in it.
ALL Black wires are Ground wires. (Negative)
You can choose ANY socket hole that has a Black wire in it.

Now touch the two probe leads of the multimeter, to their respective straightened out paperclips.

Red (Positive) probe lead of multimeter, to straightened out paperclip in Orange wire socket hole.
Black (Negative) probe lead of multimeter, to straightened out paperclip in Back wire socket hole.

You should be reading 3.3 Volts DC.

(Or if your multimeter kit has special probe lead, that would take the place of a straightened out paperclip, of course use it instead)

Know this;
A) If ALL of the LED's ('lights') were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical CPU (Processor) can use 51 to 130 Watts of power.
Just depends on what Processor (CPU) it is.

This is why a Power Supply with a weak voltage power rail, will not have enough power to turn the Processor ON, but will have enough power to light those simpy LED's, and spin fans.

Frigging computer doesn't work, but the Processor, and graphics chipset that is Integrated on the motherboard, is fine huh?
Yeah right.

You have a bad Power Supply.
Weak voltage power rail.

Take a multimeter set to DC Voltage, and check the voltage of the 3 main voltage power rails; 3.3 Volts, 5 Volts, and 12 Volts. (All are DC)

An inexpensive multimeter can be purchased for as little as $5 to $12. Available in a multitude of stores. An auto parts store is but one example.

A) Orange wires are 3.3 Volts
B) Red wires are 5 Volts
C) Yellow wires are 12 Volts.

D) ALL Black wires are Ground wires.

Positive red ( + ) lead of multimeter touches the power wire.
3.3 Volts (Orange), 5 Volts (Red), or 12 Volts (Yellow)
Negative black ( - ) lead of multimeter touches ANY Black wire.

[In comparison two D cell flashlight batteries store 3 Volts DC.
In case you are worried about getting shocked ]

Looking back at the Playtool link, look at the photo to the far right.
24-pin ATX main power cable is plugged into the motherboard as shown.

Lay the computer on it's side.
A straightened out paperclip is inserted into the Back of the main power cable's connector, and down into the socket hole with an Orange wire in it. (The Back is where the wires go into the connector of the main power cable)

Goes RIGHT NEXT TO the insulation of the Orange wire, and has to go far enough down in the socket hole, to touch a metal terminal at the end of the wire,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

Another straightened out paperclip, is inserted down into ANY socket hole with a Black wire in it. (I would keep the two paperclips separated pretty far though)

Power supply, (Computer) is plugged into power, and turned on.
Touch the probe leads (Red and Black) of the multimeter, to the two straightened out paperclips.
You should be reading very close to 3.3 Volts (DC)

Do the same test on a Red wire. You are testing for 5 Volts now.
Now the same for a Yellow wire. Testing for 12 Volts.

[All the 3.3 Volt wires (Orange) end in the same central locating point, inside the Power Supply.
Crudely explained that central point, or tap, is the 3.3 Volt power rail.

All the 5 Volt (Red) wires end in one central locating point.
Same for all the 12 Volt (Yellow) wires.
Hence 3.3 Volt power rail, 5 Volt power rail, 12 Volt power rail ]

Light Emitting Diodes may light up, fans may spin, but there is not enough power to turn the Processor on.

1) If ALL of the LED's were on at once mdrod, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 125 Watts of power. Just depends on what Processor it is.

The radio will not hold memory

If your radio will not hold memory then you are lacking a constant 12 volt power source. Check the yellow and red wires at the radio. The yellow wire should be connected to a constant 12 volt power source (battery) and the red wire should be connected to a switch 12 volt power source (accessory or ignition).

When my computer starts the power light will blink and the fan starts. When the computer first had problems it froze and the fan turned on and wouldnt stop. I also smelt a burnt rubber smell. I read to...

Yes the voltmeter measures the voltage.
When you power up the computer to test the voltage on the 4 wire connectors.
Test the voltage red and balck wire should read 5 volts.
Test the voltage yellow an black wire should read 12 volts
If the burning smell is from the power supply then most likely a capacitor has blown in the switch mode power supply.
I would advise you purchase a new power supply, do not try and repair it, these mains devices can be dangerous if you don't have knowledge.

What are the outputs of the varios plugs & sockets of a Delta Electronics power supply model SMP-420BB when supplied with 230 volts AC input

Forget about the individual plugs. Concentrate on the wires.

The Delta SMP - 420BB is just another
Switched Mode Power Supply.

(SMPS shortened to SMP by Delta. I'm speculating here, but I'll bet the 420 stands for 420 Watts)

No matter what the input voltage is, the SMPS will only put out three main voltages.

1) Wires with Yellow insulation are 12 Volts
2) Red wires are 5 Volts
3) Orange wires are 3.3 Volts

ANY Black wire is a Ground wire.

For example:
1) 4-pin white Molex power cable.
1 - Yellow wire
1 - Red wire
2 - Black wires

(4-pin Molex power cable is also referred to as a Peripheral power cable)

I WOULD LIKE TO KNOW HOW TO HOOK UP THE RED AND YELLOW WIRES FROM A JVC KD-R400 CAR STEREO TO THE WIRING OF A 1999 PONTIAC MONTANA

The red should be ACC. Meaning it only supply 12 volts when the ignition is in the acc position or in the on position or when the car is running. It do not supply 12 volt if the ignition is off. The yellow wire is Battery(sometimes called B+). That means it has 12 volts at all times even the ignition is off. This wire is responsible for memory. Get a meter or a test light. Turn the ignition off and find which wires has 12 volts, you caonnect that to the yellow wire. Now turn the ignition key to ACC, and find the wire that has 12 volts, now turn the key off , the 12 volts should go away, You connect that to the red wire.
