In Electrical and Electronics Engineeringwe use different types of drawings or diagrams to represent a certain electrical system or circuit. These electrical circuits are represented by lines to represent wires and symbols or icons to represent electrical and electronic components.
It helps in better understanding the connection between different components. Electricians rely on electrical floor plan which is also an electrical diagram for doing any building wiring.
Engineers use various types of electrical drawings to highlight certain aspects of the system but the physical circuit and its function still remains the same. Some of these electrical drawings or diagrams have been described below. A block diagram is a type of electrical drawing that represents the principle components of a complex system in the form of blocks interconnected by lines that represent their relation.
It is the simplest form of electrical drawing as it only highlights the function of each component and provides the flow of process in the system. Block diagram are easier to design and is the first stage in designing a complex circuit for any project.
It lacks the information about the wiring and placement of individual components. It only represents the main components of the system and ignores any small components. This is why; electricians do not rely on block diagram. The following two examples of block diagram show an FM transmitter and a variable frequency driver VFD.
This diagram shows the process of converting an audio signal into frequency modulated signal. It is pretty simple and easy to understand. Each block process the signal and pass it to the next one. Practically, the FM transmitter does not look like this, because the block diagram omits the individual components.
This block diagram shows a 3 phase AC power supply conversion into a DC which is again converted into a controlled AC supply. It is quite a complicated process but this diagram simplifies the process into blocks for better understanding. The block diagram provides an idea how the process is done by not delving too deep into the electrical terms but it is not enough to implement a circuit. Each block is a complicated circuit that can be explained using other drawing techniques described below.
The schematic diagram of an electrical circuit shows the complete electrical connections between components using their symbols and lines.

Unlike wiring diagram, it does not specify the real location of the components, the line between the components does not represent real distance between them. One can easily troubleshoot certain schematic by applying electronic circuit theory. It is the most common type of electrical drawing and are mostly used in implementing electrical circuits by technician. Most engineering student rely of schematic diagram while developing various electrical projects. This is a schematic diagram of a voltage amplifier.
It uses various symbols to represents the electrical components and the lines to represent the electrical connection between their terminals. The practical circuit may vary in appearance but the electrical connection and its function will remain the same. Single Line diagram SLD or one-line diagram is the representation of an electrical circuit using a single line.
As the name suggests, a single line is used to denote the multiple power lines such as in 3 phase system. Single line diagram does not show the electrical connections of the component but it may show the size and ratings of the components being used. They are used for determining and isolating any faulty equipment in any power system during troubleshooting. The SLD diagram uses dedicated electrical symbols and icon for different components.
A common example of a 3 phase power circuit to represent using a single line diagram would be the power transmission and distribution to the consumers. This diagram clearly shows a 3 phase power generating station that transmits the power to the consumers below.This page is dedicated to Wiring Diagrams that can hopefully get you through a difficult wiring task or just to learn some basics in how to wire a 2-way switch3-way switch4-way switchoutlet or entertainment component diagrams.
If you don't see a wiring diagram you are looking for on this page, then check out my Sitemap page for more information you may find helpful. How a 2-Way Switch Works. The power source is coming in from the left. Notice the black wire is the only wire that we are controlling through the 2-way switch.
You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc. The white wires are wire nutted together so they can continue the circuit. Just use your mouse pointer on this diagram and follow the current flow from black wire hot wire through the 2-way switch, then to the load and return through the white wire neutral.
This should give you a good basic understanding how the 2-way switch circuit works and will help you in adding or changing a 2-way switch. How a 2-way Switch Circuit Looks. So the circuit above when explained should give you a good concept on how this basic circuit works. When wiring a 2-way switch, this image on the left will show how the connections should actually look when all connections are made.
Take notice of the ground wire. It's very important that the ground or bare copper wire is connected to the green screw on the switch. All grounds are connected, and the ground is connected at the light when possible. If no connection is available, then attach the ground wire to the box in a solid way.
How a 3-Way Switch Works. When wiring a 3-way switch circuit, all we want to do is to control the black wire hot wire to turn on and off the load from 2 different locations. The diagram here will give you a better understanding how this circuit works and how a 3-way switch is wired. The source power black wire is coming in from the left.
It ties into the common on the left switch see image below. When the left switch is toggled, it connects to the upper circuit and now the circuit is open at the right switch which turns off the light. Toggle the right switch and it connects to the upper circuit and now closes the path and turns the light back on and so on.
How a 3-Way Switch Circuit Looks. So the circuit above when explained should give you a good concept on how this 3-way circuit works. When wiring a 3-way switch, this image on the left will show how the connections should actually look when all connections are made.
The best way to simplify wiring a 3-way switch is this. By looking at the moving 3-way switch above, the hot black wire coming from the power source will always attach to the common screw on the 1st switch in the circuit.
Then the traveler wires are connecting both switches and it does matter which wire goes to which traveler screw. Now with that said, just look at the switch again and look at the circuit. There you have it, 3-way switch wiring simplified. It's very important that the ground or bare copper wire is connected to the green screws on the switches. How a 4-Way Switch Works. You must understand the 3-way circuit above in order to get the 4-way circuit.
A 4-way switch circuit is nothing more than wiring a 4-way switch between the 2 3-way switches in a 3-way switch circuit. Now don't let this be confused with where the switches are physically located in your home. This is how the circuit is structured.Ask a Question! Directory of Electrical Repairs and Wiring Diagrams.

Architectural wiring diagrams piece of legislation the approximate locations and interconnections of receptacles, lighting, and enduring electrical facilities in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit. Wiring diagrams use tolerable symbols for wiring devices, usually interchange from those used on schematic diagrams. The electrical symbols not abandoned law where something is to be installed, but with what type of device is physical installed.
For example, a surface ceiling buoyant is shown by one symbol, a recessed ceiling roomy has a alternative symbol, and a surface fluorescent lighthearted has option symbol. Each type of switch has a stand-in tale and so get the various outlets. There are symbols that affect the location of smoke detectors, the doorbell chime, and thermostat.

A wiring diagram is a straightforward aesthetic depiction of the physical links as well as physical layout of an electric system or circuit.
It reveals how the electric cables are adjoined as well as can likewise show where components as well as elements could be linked to the system. Use electrical wiring layouts to help in building or manufacturing the circuit or electronic device. They are additionally valuable for making repair work.
Do It Yourself fanatics use electrical wiring representations however they are likewise common in home building as well as vehicle repair. For instance, a home building contractor will certainly desire to verify the physical location of electric outlets and also light fixtures utilizing a wiring diagram to prevent costly errors and also constructing code infractions.
A schematic shows the strategy as well as function for an electric circuit, yet is not interested in the physical design of the wires. Electrical wiring representations show exactly how the wires are connected and where they ought to situated in the real device, as well as the physical connections in between all the parts.
Unlike a pictorial representation, a wiring diagram makes use of abstract or simplified forms as well as lines to reveal elements. Pictorial representations are typically images with labels or highly-detailed illustrations of the physical parts.
If a line touching another line has a black dot, it implies the lines are attached. Many symbols used on a wiring diagram look like abstract variations of the actual things they stand for. A switch will be a break in the line with a line at an angle to the cord, much like a light button you could flip on and also off.Hi everyone, I'm looking for a good wiring diagram of the AC system, that includes the wire colors.
On my friend's LS2 the AC compressor does not turn on anymore, even though the pressure in the AC system is up to specs. I wanted to find out if the clutch has gone bad or where the problem is otherwise, but there are 2 wires instead of 1 going to the clutch, and also elsewhere 3 wires where i expect 2 etc.
Now i don't know where to apply voltage to without damaging something else.
House Wiring Diagram
The wiring diagrams on autozone's website did not help since they don't have wire colors nor even the correct number of wires. Can anyone help? Thanks a lot in advance. Re: LS2 AC wiring diagram.
ON is when pressures are read and with certain models, engine rpm must be 2k to assess pressures on low and high side. The coil for some compressors are grounded to the compressor with only one wire connection as the power input. Others like yours doesn't connect directly to the compressor body and run a second wire to the connector to ground somewhere else on the engine block.
You can safely power any wire with 12v and ground the other connector. If 12v power results in a loud click with the clutch engaging then the coil is fine. No click heard or clutch engagement means the thermal fuse blew and either compressor or coil replacement is necessary.
Unless you know how to source compressor parts, replacing the compressor is likely. The L-series use a three wire pressure transducer and cannot be bypassed as easily as the two-wire sensors.
Be forewarned; do not use any sealer unless you're willing to compound the problem with a higher repair bill when sealer fails. And it will, period. Find and fix the leak first. This applies to any car. Thanks, fdryer, for the explanation of the compressor wires.
Will get to work on this sometime soon. I read that on the LS2 it is near impossible to change the clutch on the compressor, without removing the compressor and discharging the system. Is that true? I have done this once on another car. And if its only the thermal switch though, can this be changed?
Thermal fuse. Whether its epoxied into the coil or not is anyone's guess. When a thermal fuse blows, there's usually a reason as they don't fail.
Coils outlast cars in normal service with few failures, caused by factors outside of normal conditions. The only purpose of using a thermal fuse that's buried into a coil assembly is to ensure protection of external wiring powering it.
Since you have experience with a compressor clutch coil procedure then you realize the difficulty attempting repairs without proper tools. The manual says if the resistance between the two AC clutch leads is greater than 3 ohms, then the clutch is fried. Anyone know if you can buy just the clutch somewhere, or can give me a part number??? For clarification and to be less confusing, a resistance reading higher than specified wouldn't necessarily mean a "fried clutch".
Electrically speaking, an open reading of resistance, the display showing 'OL', not 0. Coils have about 3 ohms of resistance. A blown thermal fuse in series with a coil simply won't show any resistance displayed, 'OL', an open circuit.
Its not easy at all to replace a the clutch plate and coil despite some here stating so. Each compressor presents its own problems.Fuse box acts as a place for passing electric current as well as safety for the electrical system of the vehicle.
