It needs to be connected to any source that has power while the vehicle is off.

Cigarette lighter on most American Cars is always on, otherwise, the headlight, taillights, or dome light would suffice.

Best of Luck.

Kenwood deck kdc-mp2035 im not sure about blue wire or yellow or red

Normally on Kenwood, blue is not usually used, it's for power antennae, make sure it's end is not bare though. Yellow would be to a continuous 12volt+, for memory. Red goes to accessory, (+12volt) where only power when key on, or in accessory position.

It sounds like the 12v battery lead has an issue and thats why they tied them in together. Once you resolve that issue and re-wire properly you should be set.

Where do you connect the memory wire on a jvc kd g110 car stero.....what color is the memory wire ?? what does hook red wire to acc fuse mean??? what wire does the red wire on the radio connect to on...

The yellow wire is most likely the memory wire as it needs to be connected to a constant 12 volt source.

"Hook red wire to to acc fuse" means you need to hook into the fuse block under an Accessory Fuse. (ie: something that can't be turned on unless the car is running or the key is in the "Accessory" position)

The red wire is explained above. It does not connect to the harness.

Just remember that the yellow wire needs to be hooked to a constant 12 volts and the red needs to be hooked to a circuit that is only active when the car is running or switched to the "ACC" position.

PC was caught in a lightning storm, and now will not boot (only at random). It seems like it's not getting power, when it does it'll boot normally. But when the storm hit my LAN was disabled and I had to...

Test whether it is the Power On switch, or the Power Supply. Since the LAN card bit the dust, you may be looking at a worse problem, though.

Bypass the Power On switch.

If the Power Supply comes on, the problem is the switch.
[One generic ATX Power On switch, that I have found fits many computers,

If the Power Supply does not readily come on, the problem is the Power Supply.

To bypass the Power On switch, you will be using a jumper wire on the
24-pin ATX main power cable connector.

Looks like this,

(Not necessarily the same color, and isn't located in the same position on your motherboard, as shown in the link)

Motherboard orientation:
Processor to the top, Ram Memory slots to the right.

The 24-pin ATX main power cable connector on the motherboard, is to the near right, of the number 4 Ram Memory slot.

In case you do not have the Owner's Manual, for your Inspiron 530 desktop computer,

On this page left-click on -
Owner's Manual - View - Download - (HTML 3.44MB)

Left-click on - Removing and Installing Parts
Left-click on - System Board Components
(System Board = Motherboard)

Number 7 - main power connector (ATX_POWER), is the
24-pin ATX main power cable connector, on your motherboard.

Referring back to the Playtool link, you will see a wire with Green insulation on it.
This is the Soft Power On wire. (PS_ON)

A jumper wire is used to connect it to ANY Black wire.
ALL Black wires are Ground wires.

[This is a DC circuit. There is a Positive, and a Negative.
A Ground wire is a Negative wire.

The green Soft Power On wire, is a positive wire containing 5 Volts.
You are completing a circuit.
The Soft Power On circuit.
You are bypassing the Power On switch]

There is no splicing of the wires to connect the jumper wire.
The jumper wire will go down into the socket holes, of the 24-pin ATX main power cable connector.

One end of the jumper wire goes down into the socket hole, containing the green Soft Power On wire.
The other end of the jumper wire goes down into a socket hole, with ANY Black wire.

The 24-pin ATX main power cable, is connected to the 24-pin ATX main power cable connector, on the motherboard.
Just as shown in the photo to the far right on the Playtool link.

The back of the 24-pin ATX main power cable's connector, is where the wires come in.
(The front of the power cable's connector is plugged into the motherboard)

I use a jumper wire that is approximately 3 inches long. (7.62cm)
An insulated wire. Both ends of the insulated wire are stripped of insulation, approximately 1/2 inch. (1.27cm)

One bare end of the jumper wire, goes down into the socket hole of the Green wire. Right next to the wire.
It has to go pretty far down in there.

At the end of each power wire, going into the 24-pin ATX main power cable connector, is a metal terminal pin. (Actually is a round hollow metal pin)
The jumper wire's bare end Must touch that metal pin.

The other end of the jumper wire, goes down into ANY socket hole with a Black wire.
(ALL Black wires are Ground wires)

Power Supply (Computer) plugged into power, the jumper wire is inserted.
The contact is a very BRIEF one. No more than 2 seconds.
(The Power On switch is a Momentary Contact Switch)

I suggest you also check the 12 Volt power rail. Check it with everything plugged in, inside the computer, and the computer on.
You need the Power Supply to have a load to get an accurate test.

There are 3 Voltage power rails in the Inspiron SMPS.
(Switched-Mode Power Supply, or just Power Supply for short)

A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail.

The main one to check is the 12 Volt power rail.
[Orange wires are 3.3 Volt.
Red wires are 5 Volt.
Yellow wires are 12 Volt ]

The Positive (Red probe lead of the multimeter, is connected to any Yellow wire, coming out of the Power Supply.
The Negative (Black) probe lead of the multimeter, is connected to any Black (Ground) wire.

See if there is an unused standard 4-pin Peripheral power cable.
It has 1 Red wire, 1 Yellow wire, and two Black wires.
Connect to the Yellow wire, and to one of the Black wires.

[Multimeter function set to DC Volts. If it has it, set it to the 0 to 50 Volt scale]

11 to 13 Volts is Okay, but I prefer the voltage to closer to 12.
11 Volts indicates it's time for a new Power Supply.

I need to know the wiring dia

all your wiring is color coated. if you have your harness from the the new reciever and you have purchased an adaptor harness which plugs into the vehicles existing harness enableling you to wire every thing as it is color coated you have red wire a yellow wire a black wire. your red and yellow are power and your black is your ground wire .your red should be be your acc or ignition wire which gives you power to the unit when the ignition is on should tie directly to the red wire on your adaptor harness, the yellow is your constant 12 volts which is for memory and keep your presest along with your time and features such as that it will tie with the yellow on the harness as well then the black is your ground the unit and will tie with the black wire on the harness. that takes care with powering the unit next you have a set of wires that you will be using to tie your sound to they are color coated as well and will tie to the new harness your front left and front right channels are white/white and black and usually gray/w a gray and white for the right channel thats your front. your rear is green/w green and purple and purple/w purple and white stripe for the rear speakers i hope that helps you out a bit

2002 malibu wiring diagram?!?!?!?!?!?!

ok, the red and yellow wires serve 2 different purposes.the yellow supplies constant power to your stereo, and the red is switched power. what youve done is combine the two, and connect them to a constant power source. like this, your stereo wont be switched with your ignition. so take off the red wire, but leave the yellow wire connected to the wire its already on. make sure your stereo fuse is good in the fusebox of the car. then, use a test light, with the ignition switch on, to find the second wire on your cars harness that has power. that will be your switched power. connect that one to your red wire, and that will solve your problem.
