Red is always Positive... Black is always Negative, ALL Cars are negative Earth... accordingly the Negative or OUTSIDE terminal is Black.. that makes the INNER one RED or positive.

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.

Power failure of motherboard


"power failure of motherboard"

I'm lost. Since when does a motherboard produce power?

Power failure AT motherboard?

You have tested the 3 main voltage power rails, coming out of the Power Supply?
A) 3.3 Volts DC
B) 5 Volts DC
C) 12 Volts DC

[In comparison two D cell flashlight batteries produce 3 Volts DC ]

http://en.wikipedia.org/wiki/Computer_power_supply#Wiring_diagrams

[ From http://en.wikipedia.org/wiki/Computer_power_supply ]

http://www.gigabyte.com/products/product-page.aspx?pid=2439#ov

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

ALL Orange wires are 3.3 Volts
ALL Red wires are 5 Volts
ALL Yellow wires are 12 Volts.
ALL are DC Voltage

ALL Black wires are Ground wires. Means Negative wires. ( - )
All power wires named above are Positive wires. ( + )

(This is a DC circuit)

Multimeter:
Positive (Red) probe lead to power wires, one at a time.
Negative ( Black) probe lead stays connected to ANY Black wire.

Looking at the Playtool link, observe the photo to the Right.
Shows 24-pin ATX main power cable plugged into motherboard.
This is what you want.

The Back of the connector is where the wires go in.
The Back of the connector, is where the straightened out paperclip goes in.

I straighten out a paperclip, and insert down into the socket hole; of the power wire to be tested.

(Orange, or Red, or Yellow)

Straightened out paperclip, slides RIGHT NEXT TO the existing wire.

Look at middle photo. See the Front of the connector? You can barely make out the ends, of the female metal terminal connectors.
This is a closer look,

http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction

At the bottom of the photo is the Front; of the female metal terminal connector.

At the Top is the Back of the connector.
The straightened out paperclip, MUST slide down into the socket hole; far enough to touch the Back of the connector.

Now do the same for ANY Black wire.
Power Supply now plugged into power, you can now touch the multimeter's probe leads, to the straightened out paperclips.

Two paperclips used at one time.
Test each voltage power rail, one at a time.

When I state Voltage Power Rail;

3.3 Volt power rail.
ALL of those Orange wires end at one central point, in the Power Supply; the 3.3 Volt power rail.

This means you can test ANY Orange wire, and be testing the 3.3 Volt power rail.

Same goes for the 5 Volt power rail. (Red wires)
Same goes for the 12 Volt power rail. (Yellow wires)

What are the voltages? Post back in a Comment.

OR,
Use a KNOWN to be good, Compatible power supply; for a temporary test unit.

Power Supply checks out OK, or you are using a KNOWN to be good, Power Supply?

White is usually always power FROM the S (Starter) terminal of the Key switch to the clutch pedal switch then on to the start solenoid. For briggs and stratton key switch terminal 4 is used for starter power. The model number you passed is for the engine only.

Without your riding mower model number I can not even begin to guess for sure. If you can locate the mower model number I will look it if and see what I can find.

This is the usual wiring off of the QUAD regulator.

I really need an explantion of where your trying to connect to and from. I am thinking your connecting from the engine alternator. IF you replaced the alternator... depending on which alternator you purchased there is a modification that has to be done to wiring harness of the alternator to the regulator.

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)

P0450 CODE ON 1997 T100 V6 PICKUP. WHAT IS it and how can I fix it?


Good day
P0450 is Evaporate emission system pressure sensor/switch
the cause could be
1. short or open in the vapor pressure sensor circuit
2.vapour pressure sensor
3. ECM

You can test with the following
you can access the ECM behind the glove box. turn ignition on,backprobe the ECM connector, on A/T models, measure voltage between terminals #1 (green/black wire) and #22 (brown/black wire) at the ECM E6 connector. on M/T models measure the voltage between terminals #1 (green/black wire) and #9 (brown/black wire) at ECM E6. if voltage is 4.5 - 5.5 volts, go to the next step. If the voltage is not 4.5 - 5.5 volts, replace ECM and retest.
2. back-probe ECM connector on A/T models measure voltage between terminals #15 (red/blue wire) and #22 (brown/black wire) at ECM E6. on M/T models measure voltage between terminals #4 (red/blue wire) at ECM E5 and connector #9 (brown/black wire) at ECM E6 connector. on all models disconnect the vacuum hose from the vapor pressure sensor. sensor is located near the brake master cylinder. connect a vacuum pump to sensor. if voltage is 2.9-3.7 volts without vacuum applied and 1.3-2.1 volts with .59 in.Hg (2kpa) vacuum applied. replace ECM and retest if voltage is not as specified go to next step.
3. check for open r short circuit in the wiring harness between vapor pressure sensor and ECM. repair wiring as necessary. if wiring harness is okay replace the vapor pressure sensor.

Hope this helps

Wiring problem


If they only way to fit your cable is by using the terminal push on connector (which, frankly, i'm not 100% sure what that's describing) and you can easily get that from your hardware store then yes, as long as you can connect up your wires without difficult and without stray copper.

Red wire is live, but white may be live as well during one aspect of operation. Usually neutral is black or blue. If your cable has red white and blue color in it then your using a 3 phase cable. A single phase 3 core cable will have red/brown black/blue green/greenyellow.

Hope this helps. Let me know.
