Where to find a 70MM fan for my eMachines?

I need a 70MM fan with 4 wires (red, yellow, blue and black) and a connector with 4 openings. I've looked EVERYWHERE but can't find one except on the eMachines website, but it's out of stock til March. If anyone has any suggestions I would appreciate it.

(I've found some with 3 wires or 3 openings on the connector)

Do you have to use all of the wires? 70 mm fans seem to be very common on  Newegg.com

What a Marvelous person!

You have described a 4-pin Peripheral power cable, ('P6'),

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

An IDE harddrive, of which the 4-pin Peripheral power cable example, is plugged into.
Another look at an IDE (PATA) harddrive,

http://www.newegg.com/Product/Product.aspx?Item=N82E16822136096

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

However, I do not know if the flat IDE ribbon cable marked Slave, goes to a secondary Harddrive, or an optical drive. (CD/DVD drive)

Either way the point is moot. BOTH of those 'squarish flat black' units, HAVE a 4-pin Peripheral power cable to them.
Another hardware component, those type of power wires CAN go to, is a computer case fan.

However not ALL power cables have to be used. Sometimes there are extra ones. These are in case they are need later.

To summarize;
The optical drive, or drives; that you put a CD, or DVD disk in; can use a 4-pin Peripheral power cable.
(IDE/PATA optical drive)

Harddrive's can use a 4-pin Peripheral power cable.
(IDE/PATA harddrive)

A computer case fan may use a 4-pin Peripheral power cable.

Or the 4-pin Peripheral power cable you see, may simply be an extra one. One if needed in the future.

The eMachines T2245 uses a Trigem (Manufacturer), Imperial GLVE (Model name), motherboard,

http://www.ebay.com/itm/New-Emachines-Imperial-GL-VE-20021218-Motherboard-Socket-478-System-Board-/121098707716?pt=Motherboards&hash=item1c320ba304

Supports an IDE (PATA) harddrive, (Or 2 of them)
Supports an IDE (PATA) optical drive, (or two of them)

I DO hope you are following Anti-Static Procedures!

Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static, BEFORE reaching inside your computer.

Computer on a table, computer Unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open, empty computer case.
This action will relieve your body of Static.

IF, you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

Also I would like to add;

The black almost always goes in the L. The others you'll have to play with. Also,you should know that this isn't the right switch for your fan.

I am looking for a way to test my GE Arctica Refrigerator Fan Motor & if need be my Electronic Board that sends power to this fan, how do I find a Wiring Drawing that say's what these 4 wires -...


The Red wire is positive around 13.5 VDC
The White wire is the negative
The yellow should also be Positive around 13.5 VDC
The blue wire should also be around 13.5 VDC

Check Connector #2 on the main board for voltage.
on all those connectors. ignore the blue/blk.
To get the fan working the red and white MUST be connected and have voltage., if the yellow does not have 13.5 dc the fan will not work. the fan will work even if it's not connected.
So, The RED and WHITE wires always have voltage. jump the yellow to red and the fan WILL work. either inside the fridge or on the board. if you jump it, remember to disconnect the yellow from the board.
You can also check the fan with external voltage outside of the fridge with a small 12vdc transformer. RED and Yellow to Positive. White to negative.
The fan rarely goes bad. It usually starts humming before it goes bad(for weeks). U might change the fan, the board and not fix it. There might be a simple short from the board to the fridge connector.

I need the wiring for the mic


Hello,
Here is the wire diagram for several common mics in relation to a 4 pin CB. Most recent 4 pin CB's such as Midland, Cobra, Connex, Uniden, etc can use 4 pin mics. The wiring is actually depending on the mic rather than the CB so long as the CB's are 4 pin as well. Once you go back to late 80's the 4 pin design was a little different. Anything new it is simpler.
Stock Mic 1- Shield (Ground) 2- Yellow (Audio) 3- Red (Transmit) 4- White (Receive)
Astatic - 4 wire 1- Shield 2- White 3- Red 4- Black
static - 6 wire 1- Shield & Blue 2- White 3- Red 4- Black Yellow NC

What is check engine code p0135


Reasons are:
HO2S no. 1 heater circut is open or shorted
HO2S no. 1 is defective
Defective ECM

Using a scan tool, read freeze frame data. Freeze fram data records engine conditions when a malfunction is detected.

Access ECM behind glove box. Turn ignition on. Using DVOM, backprobe ECM harness connector. If DTC P0135 is set, measure voltage between ground and terminal No. 3 (Blue/Black wire) at ECM harness connector E10. If DTC P0155 is set, measure voltage between ground and terminal No. 4 (Yellow/Red wire) at ECM harness E10. Voltage should be 9-14 volts at each terminal. If voltage is as specified, replace ECM.

If not, Disconnect suspect HO2S No. 1 harness connector. Measure resistance between terminals B+ (Black/Yellow wire) and HT (Blue/Black wire on bank No. 1 ; Yellow/Red wire on bank No. 2) at HO2S connector (component side). Resistance should be 11-16 ohms at 68 degrees F and 23-32 ohms at 1472 degrees F. If resistance are not specified, replace appropriate HO2S. If resistance are specified, Repair wiring between ECM and appropriate HO2S, or between appropriate HO2S and EFI main relay (Black/Yellow wire at HO2S and Red wire at EFI main relay)

The red is positve (+) 12 volts. The black is negative (-) ground. The yellow is sensor (RPM) and the blue is control (PWM). Don't use the yellow and blue. If it's going to run it will be off the black and red.

Need wiring diagram for Sony XM-E70 Equalizer/Amp


You need 1 thick ground cable ( usually brown)
you need 1 thick power cable ( same thickness and wire as ground usually red )
you should have 1 rem wire ( thin blue )
RCAs, 2 for sub, extra 2 for 2 speakers.
The rest I have no idea what they are.

You need speaker cables to sub or amp.

Some products use different colouring. Maybe the 9 pin connector is for head deck to speakers.
