Well, electricity is electricity and wiring circuits are wiring circuits. I do not have a 2002 fxdl electrical service manual either so cannot help there. On a 2003 the white wire goes from the headlight to four pin connector 38B and from there to four pin main harness connector 38A pin 2 and from there to connector 20A pin 4 and from there to (fxdl only) connector 21A pin 2 to connector 21B pin 2 to high beam indicator light which has BK wire ground going to 21 B pin 6 to 21B pin 6 after which it joins other BK ground wires to speedo and to 20B pin 12 and then to 20A pin 12 to TS/TSM pin 12 (ground)

POWER from ignition switch into lighting 15 amp fuse by connector 38 pin C R/BK and out from fuse by BE to connector 24A pin3 and out connector 24B pin 3 BE into handlebar switch then out from handlebar hi/lo switch into connector 24A pin 4 W and then out from 24B pin 4 W to connector 20A pin 4 W (which joins to speedo connector 20B W and also goes to connector 38A pin 2 W which goes to 38B W pin 2 to the headlight high beam element on the right side pin with the low beam element connection on the left side (on the wiring diagram) (Ground wire is also on the (diagram) right side and goes also to HDI position lamp is on the bike and HDI position light power is from connector 38B pin 1 O/W etc.


Connector 20 is a 12 place Multilock is console gauges connector located under the console on fxdl

Connector 21 is a 10 place Multilock console gauges connector located under the console on fxdl

Connector 24 is a 6 place Deutsch left hand controls and horn connector located on the frame backbone

Connector 38 is a 4 place Multilock headlamp connector located on the frame backbone

Not a problem, but it would be handier to have the manufacturer Name, and Model Number.

SMPS = Switched-Mode Power Supply. The style used in personal computers now,

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

A) Main power cable:
There are three styles;

1) The old AT style that has two separate connectors. The connectors BOTH connectors have BLACK wires towards one side.

The connectors also have ONLY one way, (Direction), they can be plugged onto the motherboard.
This is due to the Lock, and Locating Tab on the motherboard connector/s, and the main power cables connector/s.

When you can plug the connectors on the motherboard, with both connector's BLACK wires facing each other, (They will be in the middle), you have them installed correctly,

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

2) The newer ATX style. Uses one power cable, and connector.
First style to come out was the 20-pin ATX main power cable,

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

20-pin ATX main power cable's connector, has a LOCK on one side.
This Lock locks over a Locating Tab, on the female motherboard connector.

To remove this power cable you squeeze in on the Top of the Lock.
The Lock operates like a see-saw on a playground. When you squeeze the top in, you remove it's hooked end away, from the Locating Tab of the motherboard connector.

To be ensured that this cable is plugged in tightly, and correctly, the Lock's hooked end will be over the Locating Tab, on the motherboard connector.

3) The newest style is the 24-pin ATX main power cable.
As computer hardware evolved, and became better, it demanded more power.
The extra 4 pins of the 24-pin ATX main power cable provided this,

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

[ Aftermarket power supply manufacturers, provide power supply's with a 20 + 4-pin ATX main power cable, usually.
You can use it as a 20-pin ATX main power cable, or use the additional 4 pin cable, and use it as a 24-pin ATX main power cable ]

4) Motherboard didn't provide enough power for newer Processors.
The 4-pin ATX +12 Volt power cable was brought out.
(Has Lock with Locating Tab on the motherboard connector, also)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

5) Motherboard didn't provide enough power for high-end graphics card.
4-pin ATX +12 Volt power cable didn't help.
The 6-pin PCI Express power cable was brought out,

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

Plugs into a graphics card.

[ Note*
In all power cables, Red wires are 5 Volts. Yellow wires are 12 Volts. ALL Black wires are Ground wires ]

Next in line was two versions of the 8-pin power cable.

A) 8-pin EPS +12 Volt power cable.
Originally brought out for server computers, that has multiple Processors.
Plugs into the motherboard.

B) 8-pin PCI Express power cable.
Brought out for more power, than a 6-pin PCI Express power cable could put out.
Plugs into a graphics card.

(6-pin PCI Express power cable is capable of handling 75 Watts.
8-pin PCI Express power cable will handle 150 Watts )

If you have an IDE (PATA) harddrive, a 4-pin standard Peripheral power cable is what you need. ('Molex' is the slang term for it's connector)

If you have a SATA harddrive you need a 15-pin SATA power cable.

NOTE*
IF, your SATA harddrive has a provision for a 4-pin standard Peripheral power cable, AND a SATA power cable;

ONLY USE the SATA power cable!

If you use both you will burn out the harddrive. Maybe not immediately, but I assure you down the road you will.
(Do not use just a single 4-pin standard peripheral power cable, either)

Optical drive/s use a 4-pin standard Peripheral power cable, if they are IDE (PATA) units.
If they are SATA units they use a SATA power cable.

The old Floppy Drives use a 4-pin small Peripheral power cable.
Same cable plugs into a Card Reader, also.

The plastic front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the cables, (Wires), from the Front Panel go to, is the Front Panel header.

Sometimes abbreviated on the motherboard as;
F_PANEL 1, or FP1, etc.

I will need to know the computer manufacturer name, and Model Number, (HP = Product Number, or P/N), or the manufacturer name, and Model Number of the motherboard, to TRY to provide this information.

Locate the case connector pins on your motherboard. This will be a bank of two rows with 10-12 pins in each row. Each pin will be about 1 cm in length.2 Locate the power lead behind the power button on your computer case. The lead will consist of two thin wires, usually white and black, held together by a small plastic cap.3 Examine the underside of the power lead for an arrow or dot. If one is present, the marking signifies the first pin. This must correspond with the first pin on the motherboard, which will also be indicated by an arrow, dot, or number. If no markings are present, the lead can be installed in either orientation.4 Place the lead over the power pins within the pin bank. The correct pins will be indicated by a diagram on the motherboard, or by a picture in your motherboard's instruction manual.5 Connect the power cable to the back of your computer, and turn the computer on.

The 2005 Spectra heating system comprises 4 main components and its associated wiring.

1. Blower Relay- supplies power to the blower motor when the key is in the on position

2. Blower motor- Located in the right side dashboard area near the passengers right foot. ( photo attached)

3. Resistor- located on the ground side of the circuit to control speeds 1 thru 3. Note" High speed bypasses this component.

4. A/C Control Module- This is the control pad in the dashboard with the blower speed controls.

The easiest way to diagnose this circuit is to split the circuit in half to determine if you have a power supply problem, ground control problem or a failed component. From your concern I am going to assume that none of the speeds work. If some of the speeds work let me know which ones and I will revise the diagnosis tree I made for you.

Key state for all tests is Key on/Engine off. Heater on and blower setting between 1 and 4.

Step 1. Verify the 30Amp blower fuse in the underhood fuse box has power and is not "Blown.

Step 2. Locate the blower motor by removing the lower kick panel on the passenger side dashboard and glove box. You will need a Phillips head screwdriver.

Step 3. Disconnect the two pin connector at the blower Connector G-02 in the attached photo. The red and blue wire is the power supply wire to the motor so with the key on/engine off check for power with a test light or volt meter. Spec: Battery Voltage. If good proceed to step 4. If no power proceed to step

Step 3.a.- the blower relay above the blower (connector G-06) and verify you have power leaving the relay. This is the red and blue wire ( Pin 4) I attached a photo of the connector to help locate the correct wire. If you have power at this pin the relay is working and you have an open between the relay and the blower motor. If you do not have power at this pin proceed to step 3.b. Verify that the relay clicks when you disconnect it from the harness and plug it back in. If it "clicks" and you have no power at pin 4 you have a bad relay. If it does not click you will need to check the power supplies to the relay. These are pins 3 (blue wire) and Pin 5 (Red wire). Be careful to check the correct blue wire as the other blue is the ground for the relay. (Pin 1). If you do not have power at either wire you have an open in the harness and further diagnosis will be needed. If you do have power at these wires then check the remaining blue wire for a ground. If you do not have a ground you may have a bad control module. To check this remove the plastic cover around the control head and radio and remove the control head from its mounting but leave plugged in to the harness. Check the white and blue wire in pin 21 of the large connector. It is located 3 pins in from the bottom left of the connector. (See attached photo). If you do not have a ground then you have a bad control module. To verify this you can ground this wire with a test light or fused wire and see if the relay "Clicks". If you do have a ground at this pin then you have an open between the relay and control head.

Step 4. - Ground check- Go to the blower motor connector and check the green and red ground wire (Pin 2) for a ground with the blower switch set to 4. This bypasses the resistor easing diagnosis. If you have a ground then the blower motor is at fault. If you do not have a ground proceed to step 5.

Step 5. Access the control head large connector. Leaving it plugged into the control head check pin 23 (Yellow black wire in the lower left corner of the connector) and verify you have a ground. If you do not have a ground you have a faulty control module. If you do have a ground you have an open between the blower motor and the control head requiring further diagnosis.

The beep you hear is a BIOS Beep Code. The computer's method of informing you something is wrong, and the area to look into for it.

The code is similar to what you may be used to.
(Afghanistan, Army? If so, hello brother/sister. 1st Cav, 13th Sig. Corp)

The BIOS Beep Code is similar to a Morse Code.

Examples:
Two short beeps followed by a long beep, a pause of silence, then the pattern repeats, over, and over.

One short beep indicates everything is okay.
This is an indication that BIOS has concluded the Ram Memory count, and everything is 5 By.

According to my sources, the eMachines T2682 desktop computer uses an Imperial GV motherboard model, made by TriGem.

The front plastic cover of your computer is the Front Panel.
The area on the motherboard that the cables, (Wires), attach to on the motherboard, is the Front Panel header.

This is the Front panel header pinout, for the TriGem Imperial GV motherboard,

http://www.e4allupgraders.info/dir1/ecase/support/front_panel_support.shtml

On this page I would like you to scroll down to the heading -
Imperial GV Front Panel Motherboard Pinouts

Looking at the pinout;

1) Pin 1 is Not used. NC = No Connection

2) Pins 2 and 3 are for the Power On LED light
[Light Emitting Diode]

Pin 2 is for the Ground wire. (GND) ( - )
Pin 3 is for the LED light power wire. ( + )

3) Pin 4 is not used. NC

4) Pins 5 and 6 are for the Harddrive Activity light. (LED)
HDD is HarDDrive

Pin 5 is for the LED power wire
Pin 6 is for the HarDDrive signal wire
(If after attaching the wires the HDD LED light is dim, reverse the wires)

5) Pins 7 and 8 are for the Power On switch.
Pin 7 is for the Ground wire.

Attaching the Peripheral cables;

1) You have an IDE harddrive. Uses a 40-pin IDE ribbon cable.
(39 actually. One pinhole is blocked off)

There is a Locating Tab on one side of the IDE ribbon cable's connector.

To wit:

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

Left-click on the blue IDE connector in the photo to the upper right.
At the top middle of the connector you will see two ridges.
This is the Locating Lug.

Now left-click on the IDE connector on the motherboard, shown in the photo to the upper right.
(To the right of the blue IDE connector)

Looking at the blue IDE connector on the motherboard, you will note there is a cutout on one side of the connector.
This is a Locating Slot.

Lining the Locating Lug up to the Locating Slot, puts the pins of the IDE ribbon cable's connector, in the correct position for the pinholes in the motherboard's IDE connector.

IF, your ribbon cable's connector does Not have a Locating Lug;

Look at the outside edge of the ribbon cable. You should see a faint Red stripe.
The Red stripe is always next to Pin 1.

Next to the motherboard's IDE connector should be a printout.
It will state PRI 1, (Stands for Primary 1), or IDE 1.
This is for the Harddrive.

[ If you see PRI 2, or SEC, (Secondary), this is for the optical drive.
(CD/DVD drive). Using this information, you will know the other IDE connector on the motherboard is for the Harddrive ]

That printout is always next to where Pin 1 is.
Therefore on the motherboard, the side of the IDE ribbon cable that has a Red stripe, will go next to the printout.

If your harddrive does not have a Locating Slot on it's IDE connector, Pin 1 is always towards the 4-pin IDE power pins.

To wit:

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

The above is a webpage from Playtool.com, discussing the various power cables used in a PC, and more specifically the standard 4-pin Peripheral power cable.

I linked it to show you a standard 4-pin Peripheral power cable, plugged into an IDE harddrive.

(A Peripheral power cable's connector, has been misnomered as a Molex connector, repeatedly through the years.
This was the name given to the first connector of this design.
It's kind of like referring to an adjustable open-end wrench, as a Crescent wrench )

Here in the photo of the rear view of an IDE harddrive, (Photo to the far left), you will see the 4 power pins.

To the left of the power pins are the Jumper pins.
To the left of the jumper pins, is the IDE interface for the 40-pin IDE ribbon cable.

The Red stripe of the IDE ribbon cable goes towards those 4 power pins.

Hi Paul,
see page 8 number 15 for location. Than see page 19, System Panel Header in your manual.
The basic wire color's for positive are red, blue, green & can also be light blue, light green, light red.
Negative wires are usually white or black. Case wire colors do vary from case to case.
To see pin one shown on page 19, (positive + for hard drive led = HDLED+). Bottom row farthest pin to the left of set. Pin two is above pin one. Pin two is, PLED+ (known as power led). Pin 3 is to the right of pin one & is HDLED- (Hard drive led, negative). Pin 4 is above pin 3 & is also PLED-, (Negative for power led). ECT!
If your new case has an internal speaker (Used for P.O.S.T, power on self test). This would connect to, Chassis Speaker Header located on page 8, number 16. Again, normally only two wires are used across the 4-pin connector. (One at each end of the connector).

To see ASRock's main site for the 775VM800 motherboard click this link:

Good luck Paul!
Run into a snag, just post the issue here.

Mike

How about a picture? Pg. 46 in your manual.
Need manual, download from Intel. (Click on link).
http://www.intel.com/support/motherboards/desktop/RC440BX/sb/CS-013608.htm


Intel RC440BX Specification
Pg. 46
Basic rules case wiring. The color black is considered ground -. Power wires + can be any other color including stripped wires. (This is standard but case Mfg change to their own specification).
Pin 1 is + power for LED Hard drive green LED, Pin 2 is -/ground for Hard drive LED.
(Pin 3 is + power for LED Hard drive yellow LED, Pin 4 is -/ground for Hard drive LED).(See more options on pg. 47).
Pin 5 is + power for case On/off button, Pin 6 is -/ground On/off button.
Pin 7 is + power for Reset Switch, Pin 8 is -/ground for Reset Switch.
Once positive & negative pins has been located each connector follows in suit.
The Intel RC440BX front case connector is in an odd location.
The user will find it hard to connect front case LED connectors while the board in installed into the case.

Good Luck!

Mike
