Understanding Auto Electrical Repairs

Nowadays, auto electrical repairs are getting more and more complicated and are already pressuring the boundaries of contemporary technology. However, they are fundamentally the same with their design three decades ago. An informative general idea of your vehicles electrical structure would be an excellent kick off. The most important mechanism of your cars electrical system, the battery and the alternator are explained underneath, in conjunction with some troubleshooting tips.

Your Cars Battery

Car’s battery is a storage piece of equipment and is employed to start the engine. The battery helps activate and control the electrical accessories set up and installed on your car. The battery is composed of six cells of heaped positive and negative lead plates, divided by insulators and wrapped up in electrolyte, which is a mixture of sulfuric acid and water. The six cells generate 2.1 volts producing an entirety of 12.6 volts. This kind of energy is stored energy and not produced energy.

On every occasion that a car show signs or symptoms of a charging or starting system breakdown, the most essential assessment and check that should be carried out first is a voltage and visual test of the battery. Realizing and learning the precise circumstance of the battery is the most excellent means to be acquainted with whether or not to suppose other system components can put off the redundant setting up of a starter or alternator, which cannot patch up the vehicle until the battery is up to bump off.

It is very recommended that you seek the help of auto electricians in order to fully be aware of the auto electrical repairs that should be done. Auto electrical repairs on batteries might be tricky that is why you should always have the backup of the professionals for this matter.

Your Cars Alternator

The cars alternator generates electricity which is employed to preserve battery storage charge and to lend a hand in operating the entire the electrical accessories, which includes the ignition and the engine control systems. The cars alternator is belt-driven by the engine and creates an alternating current which is transformed to twelve volts direct current by means of the rectifiers or diode bridge.

In contradiction to popular idea, an alternator does not continuously generate electricity. It sequences on and off at the same time as demand goes up and down. The battery bumpers it from the electrical demands of the car, and it merely works sufficiently to uphold system voltage. By the side of the highest point of effectiveness and competence and for its durability, the alternator is ought to be charging not exceeding half of the time.

By checking out all simple circuits first can to the highest degree decrease your troubleshooting time and needless replacement of your alternator or auto electrical repairs. You can always ask the assistance of the auto electricians in order for you to fully understand the different matters with regard to alternators and its maintenance.

All in all, your vehicles electrical structure should be entirely maintained and preserved every two years or at whatever time auto electrical repairs for any type of drive ability breakdowns occur.


Car Electrical Problems – 4 Easy Strategies To Deal With The Check Engine Light

Strategy number one.

What is the engine management light? What does it mean?   Depending on your vehicle you will get the message ‘engine service soon’ or a small clock icon or perhaps a number of green bars. These are self explanatory and are to let you know that a service is soon due. This is built into your vehicle to help you maintain it in the best condition. On board diagnostics (OBD ) was introduced in US to help maintain vehicles and keep environmental pollution to a minimum. EOBD simply means European on board diagnostics, the EU equivalent of the American system.

Strategy number two.

What is  the ‘check engine light’? How can you solve the problem when the engine light comes on? The ‘check engine light is different to the engine management light. It indicates when something is wrong, a malfunction in one, or more, of the sensors and meters sending information to the car’s brain – the ECU. If the ‘check engine’ light comes on it sometimes means a fault and your vehicle enters into a “limp mode” . This means it is running in a ‘safe’ mode – a program which means more fuel consumption and increased emissions. To turn off the ‘check engine light’ you will need first of all to read the fault code to find out what is wrong. When you know the fault,  you can put it right,  reset the codes and have the ‘check engine light’ switched off.

Let’s take an example.

After the check engine light comes on you locate the data link connector (DLC). It is placed under the dash in the passenger footwell on your particular car and is a ‘D’ shaped female plug with 16 pin-outs. When you connect a code reader to this data link connector  it automatically turns on and gives you a Diagnostic trouble code (DTC). Let us suppose for the purpose of illustrating the problem that the code is P0100.

We look this code up in a table and find it is a  Mass or Volume Air flow circuit malfunction. On further examination we find that  code P0100 may mean that one or more of the following has happened:
The Mass Air Flow meter (MAF) may be disconnected, or a wiring connection may be bad or the MAF sensor may be faulty. You are now in a position to make checks, put the problem right and reset the code. If everything is OK your car will return to normal running.

Strategy number three

How do you get to read the error code? Reading the error code.

The basic answer to this is you use a code reader. Fortunately all code readers will read Diagnostic trouble codes(DTC).  Code readers can be simple – ones that read Diagnostic trouble codes, – and they can be more complicated (and more expensive). ‘only the better ones will read ABS, Transmission codes and reset engine service lights.’ If you want a code reader that is multi-purpose and covers every vehicle you will have to pay top dollar.  When you plug in your scanner it will automatically turn on and should give you instructions to show you how to retrieve the trouble code. As soon as you have the code you can interpret it from the chart (supplied with your code reader) or look it up in your Workshop manual or go online and find the code details there. (there are many excellent websites )

Strategy number four

How do you use the code reader? Where do you plug it in?

The scanner plugs into the Data Terminal Connector (DTC) usually located in the driver or passenger foot-well. These data terminal connectors are also called data link connectors. They are located in a variety of different places on different vehicles; have a quick look under the dash, or in the passenger foot-well. It can also be located in the center console, sometimes behind a plastic cover. Your owner’s instruction manual should have more information.


Identifying Car Electrical Problems

Even though gasoline is the fuel that most vehicles use, each vehicle has an extensive electrical system that not only starts the car, but powers and runs all of the electrical systems. If any component of this complex electrical systems fails of gets faulty, your vehicle could get stopped in its tracks. You can’t go very far with a faulty alternator or a dead battery. In any vehicle, there are at least 4 different components that are needed just to start the car. If any of these systems gets faulty or fails, you won’t be going anywhere until you fix the problem. The purpose of this article is to help you identify and diagnose the particular electrical problem you might be having and a few tips on what you can do to solve the problem.

Let’s start at the beginning. When you put the key in the ignition and turn the key, the ignition switch sends a signal to the solenoid and the solenoid closes the circuit that sits between the battery and the starter, which causes a large amount of voltage to flow out from the battery and to the starter to turn your engine over and start the car. After that happens, the alternator takes over the powering of most of the electrical systems and also begins to quickly recharge the battery for the next time you’ll need to turn on the car. Your coil and spark plugs give the spark for combustion to light the fuel air mixture that’s in the combustion chamber to run the car as far as it needs to go. If any one of the systems gets faulty or breaks down, you might have some large problems to deal with.

So here are a few tips for finding out which electrical problem you might be having. If your car is completely unresponsive when you turn the key, but your headlights still work, then you most likely have either a bad starter or solenoid. The battery still has power because your headlights still function, but the power can’t get to the engine to turn it over because of a bad starter or solenoid. If the car is unresponsive when you turn the key and the headlights don’t come on, then you might have a loose connection on the cables that attach to your battery, or you may have enough corrosion that power can’t flow from your battery.

If your car responds when you turn the key but you don’t have enough power to turn on the car, then you most likely have a bad battery. This isn’t necessarily indicative of a completely bad battery, because at times, if you let a car sit idle for a period of longer than a week, the battery will start to lose voltage. This doesn’t mean that the battery is bad and it should run just fine once you jump start your car and recharge the battery. If you haven’t let your car sit idle, and have noticed that it’s becoming increasingly difficult to start your car, then you’ll probably need a new battery. Batteries wear out every few years and won’t hold a good charge anymore. If you haven’t bought a new battery in a few years and you’re having trouble starting your vehicle, you most likely will just need to buy a new battery. I hope this helps.
