How Does Alternator Work and What is the Cause of Its Failure

Most mechanical parts will fail after a certain period of applications. The failure of them may result from many reasons. It is also the same situation as to the alternator. An alternator is part of the charging system of the car that produces electricity for many devices. As one type of generator, it transforms mechanical energy into electrical energy. Although the car’s battery supplies some electricity, most of the electrical mechanisms within the vehicle, require the alternator’s steady stream of power.

It is mainly a mechanical device which conceals a pulley, wheels, brushes and wires, which hooks to the crankshaft and runs to the battery. This way, the gasoline powers the engine to turn the crankshaft, which in turn connects to the alternator. The alternator converts that motion into current whenever the car is running.

How does the alternator work? Generally, the belt (from the crankshaft) connects to a pulley system, called the rotor, such that when the belt is turning, it moves magnets across a special surface, called a conductor. The alternating current is controlled by a voltage regulator to keep the voltage steady.

As is mentioned above, the alternator may fail because of many different causes. First one is the belt slippage. A worn or damaged drive belt can slip on the alternator’s pulley wheel, causing the unit to put out a reduced voltage. A slipping belt can make the alternator undercharge the system, which will eventually kill the battery and damage the alternator.

The second one is the losing ground. The primary mount of the alternator serves as the negative ground and usually the mount will be wired to the vehicle’s frame with a large cable. This cable is held onto the mount with one bolt, and it is known to become loose or disconnected. When the alternator loses its ground, it can become damaged as it surges and could cause catastrophic damage to the voltage regulator within it.

In addition to them, a dead or dying battery or the failed plates can also lead to the failure of the alternator. Although it is hard to tell when your alternator has problems, we should still pay attention to those signs. Sometimes a harsh noise, or intermittent headlights, will cause serious problems. Check to make sure the belts on the alternator are not cracked, or improperly tightened, before you replace the entire thing. A rebuilt alternator can be a reliable, but less expensive, option if you need it repaired.

The Pros and Cons when Using Used Transmissions vs Remanufactured Transmissions

So you have to replace your transmission and you are wondering what are the pros and cons when it comes to used transmissions vs. remanufactured transmissions. The main difference between used and remanufactured transmissions is that a used transmission is just that it’s used; it was in a car that is likely not on the road anymore. A remanufactured transmission has been rebuilt by a machine shop to bring it back to factory specifications this includes replacing all internal parts inside of an original transmission casing.

The remanufactured transmission is usually going to have a couple key advantages over a used one. The first on is that a remanufactured engine because a machine shop has re-built it and recertified it will come with a warranty of some kind. A used transmission is likely to be sold as is with no warranty or 30 days at most and no guarantees about how long it is guaranteed to last you.

Another advantage of a remanufactured transmissions vs. the used transmission is that a remanufactured transmission has usually had any issues with the transmission fixed as a part of the re-build process where all of the internal parts are replaced however a used transmission has had nothing fixed on it so it’s a crap shoot as to whether it will work for another 10 years or 10 miles.

The one caveat to the rebuilt engine being more preferable a used one is that you need to know it was re-built by a quality shop. A rebuilt transmission is only as good as the machine shop that repairs it. Using quality parts and techniques for the rebuild is essential. If you or your mechanic are buying from a reputable re-builder you are very likely to get a transmission that will last you a very long time.

You are likely going to be working with a mechanic to get your transmission replaced and your mechanic likely has suppliers he works with for transmissions. One of the ways you can sometimes save big money is by getting quotes separately for the part and the labor. This shows you how much of the total job is going into the buying the remanufactured or used transmission. Sometimes a little research and time will make it so you can find the part much cheaper and then deliver the transmission to your mechanic and only pay for the labor.

Ultimately unless you know exactly where the used transmission is coming from when it comes to the used transmissions vs. new transmissions battle the remanufactured transmission is usually the clear winner.

What Factor to Consider when Buying Car Speakers

Research has proven that getting the right car speakers requires you first carry out a test on them, something that can be well achieved through critical listening to the quality of sound they produce. Ideally, this means that you need to sample the manner in which they produce some of the sounds that you are familiar with. Instruments accompanying the audio reverberating through the speakers ought to sound as natural as possible, and so is any other sound they produce. Ensure that you adjust the treble and bass to levels that are comfortable, as you seek to find out how they can sound in their extreme. Remember that quality car audio components are those that produce the highest quality of sound even when volume levels are high.

Experts have warned against the purchase of car components from sales people who carry out an A/B comparison of various types. This is simply because of the fact that they are bound to tamper with volume and other aspects of sound, in a bid to try to persuade you into buying the more expensive ones. It is important to consider the space in which the speakers are supposed to fit. Plainly put, being realistic is the way to go in regard to purchase of car speakers, as there is no need in purchasing those that might not fit well into the available space inside your vehicle.

It is a common phenomenon to encounter speakers fitted in such a way that the windows cannot comfortably roll down. There are others that are installed in such a manner that it becomes difficult for the vehicle’s air conditioning system to function normally, since they interfere with the dash board structure owing to their size. Low-end sound is the best type and as such, you ought to strive to get car audio components producing this quality without also compromising on the space inside the automobile.

Amplifiers are known to go along way in improving the sound quality of car audio components, though you need to know that there are times when they are not required. For instance, when you are in possession of car speakers that are first class, you have no need for an amplifier. This is because such components are fitted with in built amplifiers. An extension would not only end up compromising the sound quality but also in transforming it into noise.

Many vehicle owners in search of quality sound output often do not bear in mind the importance of the material used in construction of the components. Well, it is of utmost importance since the higher the quality, the better the output. In addition, car speakers that have been manufactured using high quality materials often last long. Always bear in mind that the reverberations from audio speakers are transformed into quality by passing through materials of high quality. The search for speakers that are aimed at providing quality and entertainment ought to be conducted in a manner that puts into account design and longevity. This simply implies that you are supposed to take your time to make the right form of evaluation when purchasing these components.

Tips for buying a Used Engine

Buying a used engine starts with knowing the specifics of what you want in an engine. This will narrow down your search tremendously and will get everything on the right track. After getting the specifics of the engine out of the way there are specific things to look for when buying a used engine.

1.   Ensure that the engine meets your specification to the T otherwise you may end up with an ill-fitting engine that you can do absolutely nothing with.

2.   Avoid being scammed by dealers both online and in person. Know the right questions to ask and be careful of pushy sales people or deals that just seem too good to be true.

3.   Request a VIN or a history check on the engine you are interested in. Make sure the check comes back with the full history report of the engine before you make any payment. Some engines may appear to be in great condition but can in fact be the victims of flooding or even rebuilding.

4.   Opt for engines with the lowest mileage possible. However, if these engines do not have good history results then forgets them as low mileage engines in poor conditions do not make any sense.

5.   Only buy engines with warranties and ask for the option to upgrade that warranty if it is less than 1 year. You will have to pay for the upgrade but it will be worth it in long run if something goes wrong with the engine during the warranty period.

6.   Be wary of one time sellers or someone who only has one engine to sell. It is more difficult to get an accurate engine history from these sellers.

7.   Choose to buy from online sites that are recommended by friends. This will provide wider variety because the online market is bigger and in addition will provide a somewhat safer environment for shopping as it was already tried and tested by a friend.

When buying used engines always do the background checks and be wary of sweet deals or pushy sellers. Take all the time you need to make the right decisions for your vehicle. Hasty and uninformed decisions may result in you being scammed and receiving an engine that may end up becoming a money pit. The tips above will help you to know what to look for when buying a used engine.

The Amplification of High End Car Audio System

The most important part of a high end car audio system is the amplification. That’s right, amplification. You can get everything else RIGHT (speakers, subwoofers, wiring, head unit, etc) and still be frustrated with the final outcome. However, if you have great amplifiers and tune them right, you will get very good results from your system. You can fix your deficiencies as you go, but at least you know you’re on the right path.

Perhaps the most talked about “most important thing” for any audio system are the speakers. Naturally, great speakers are very important to high end sound but in order to get the most of them (and justify their high cost) you’ll need great amplifiers to do so. Often times I’ll see discussions about what speakers to buy and the amplifier discussion that follows is very complacent like “Oh, just make sure you have at least 150 watts per channel and you’ll be good”.

If you do this, you’ll most likely be in for a big letdown. There is far more to an amplifier’s quality than how much power it produces in watts. Many of the factors that contribute to a quality amplifier are beyond what is printed in a spec sheet.

So what else should we be looking for? Knowing what “Class” it is helps (e.g. Class A, B, A/B, D). Depending on your application and your car’s electrical system, one of these classes will be ideal.

Knowing the dimensions and weight of an amplifier also helps. A very light amplifier with a tiny footprint putting out say 150 watts per channel versus an amp 4 times the size and weight putting out the same power should leave you suspect of the smaller amp (in many cases).

Knowing if the amplifier is a high current design or not is also critical. Since current is what actually drives the speakers, it is important that you get a high current amplifier. Power in watts is the product of current times voltage. So it is very possible for two different amplifiers putting out the same power in watts to have different current and voltage ratings.

Finally, you need to know what type of amplifier you need in your particular application. An amplifier to drive a full range component system might be different than one needed to drive a pair of tweeters, or a pair of subwoofers.

So to repeat, speakers are important but not as important as the amplifiers…in a HIGH END SYSTEM. To truly experience the power and ambience of the music, a good amplifier is imperative.

Some Common Winter-Related Car Problems and How to Solve It

When the days grow shorter and the temperature begins to drop, we know that the cold season has begun. This is the time for common winter-related car problems to surface, disrupting our commuting schedules, wreaking havoc on our inner peace, and making it necessary to call for help.

All of us are aware that we should perform routine seasonal maintenance, but that advice is routinely ignored. The icy wind is hard not only on living creatures, but wreaks havoc on machines, too. One of the biggest problems people routinely encounter is trouble getting the car started.

In cold temperatures the battery suffers. The amperage required to start things up on a warm day is often cut in half. A battery that is under-performing may start up with no problems on a balmy summer morning, but may not accomplish that same feat when temperatures plummet. In many large cities, cars are often parked on the street, and the starter mechanism and associated parts may become frozen. The battery will be unable to budge them.

The solution to that particular problem is, of course, preventive maintenance. Batteries need regular servicing, but to avoid injury from battery acid, many people prefer to let a qualified mechanic do the job. A simple checkup may save lost wages when a dead battery prevents you from getting to work. Plus, there is real danger when a car is stranded in the cold.

During very cold weather, the fuel and fuel lines may be adversely affected. When a tank full of gasoline condenses, it may produce up to a pint of fluid. The problem occurs when the engine is turned off, and that same condensation forms inside fuel lines. The gasoline is unable to reach the throttle, and multiple attempts to start the car only make things worse, ending in damage to the starter mechanism.

One way to avoid this is by using the proper “dry” gasoline if your car can handle it. Dry gas means that the fuel has had its hydrocarbons removed, and is basically ethanol. Ethanol can act as an antifreeze, allowing proper combustion. Be careful, however, because some cars equipped with fuel injection may actually run worse. It is a good idea to check with your mechanic before putting any in the tank.

The oil and coolants in the engine are important no matter the season. Although the oil plays no direct part in the actual start-up, using a thinner weight can prevent coagulation in extremely low temperatures. The oil needs to be able to move into the engine once it starts, and thick oil may end up causing overheating. Coolant contains antifreeze, which needs to be properly mixed in order to avoid possible engine block damage if overheating occurs.

If the car fails for any cold-related reason, be sure that you carry a kit for such common winter-related car problems. It should contain a first aid pack, of course, but in cold weather you also need to carry jumper cables. In addition, every motorist living in very cold regions should always carry extra gloves and a hat, duct tape, a flashlight, and easily stored food such as granola bars and water. In dangerous circumstances these simple items could become lifesavers.

Car Stereo for Music Lover

There will be no day when you do not use your car. Who wouldn’t like to listen to a bit of music when you are in the car? Especially when you are stuck in traffic or somewhere and are getting really bored, music can be of great help. But then, you should have a good music system that will enjoy music better.

There are many parts that are involved in producing good quality sound in the car. It just does not involve a set of speakers and any stereo. A car stays with us for a long time and when you choose the stereo you need to choose one which will surely last long. There are very well defined models that are available in the market nowadays. Even when you are choosing the speakers, there are a lot of speakers available.

It should have the right amount of bass and sound that makes us enjoy the music better. If the equipment is not good, it will affect the sound quality very badly. A car is comparatively smaller to a room and to adjust music in such a place is very difficult and so choosing the equipment in such a place is very difficult.

So, it is not just 2 speakers. You can have a lot of speakers positioned in your car. It can be fixed in the boot of your car, on the doors, beneath the seat and wherever you want to. You can also install other equipment like subwoofers, amplifiers etc.

A model called the The Daily Commuter is an excellent example for the 21st century car stereo. Car stereo subwoofers, car stereo amplifiers and all come in this. The models have a powerful subwoofer, satellite radio and also, a very important addition to all latest equipment, a Bluetooth receiver.

The Road Warrior is another model and it is a bit more different and has more options. It has a satellite radio and amplifier. Who does not have an iPod or an mp3 player these days? So, this device lets you plug in your players with the help of an adapter and it has easy control over them. The speakers are just perfect for travel. In addition to the car stereo, it also has a navigator, which lets you see where you are going.

There are also models that have a portable stereo system so that the ones traveling along with you can choose the songs they want to hear. There are also models which includes a remote control so that it is easier for you to select songs of your choice.

Adding Car Capacitor to Your Car

Car enthusiasts would generally ask this query, “Do I need a car capacitor”? To answer this particular question you should know the kind of vehicle system you got. If you are the kind who frequently upgrade your car’s audio system but do not know whether the current electrical system are designed for its power needs chances are you may need one, because some vehicles are not able to handle high energy systems.

Tsunami HCAP-5 Capacitor is a reasonable addition for your system due to the fact that not all vehicle batteries can handle high capacity car audio systems. You will observe fluctuation of power whenever your headlights dim during peak usage or when a largemouth bass drum strike. It also filters the AC voltage for amplifier power that can produce disrupting noise.

A car audio capacitor such as the Tsunami HCAP-5 Capacitor basically amasses power for the car’s electric usage. It provides additional needed energy in order to power the amplifier to produce awesome sound especially when producing a bombastic largemouth bass sound.

Just one Farad of capacitance is actually recommended for each 500 w of amp power nevertheless, you can never have too much capacitance for the car’s electric program. The Tsunami HCAP – 5 is a 5.0 Farad high-powered hybrid capacitor that accompanies a digital volt meter. It’s two 1/0 or even 4-gauge inputs as well as four 1/0 or even 4-guage outputs for any multi-amp system as many as 3 amplifiers. The Tsunami capacitor can provide a total of 5,000 watts RMS. This is more than enough to power your car amp.

The Tsunami HCAP-5 electronic hybrid car capacitor is available in aluminium outer shell with stainless plastic highlights. It includes a hinge that hides the terminal contacts. It has a blue electronic LCD volt meter. The flashing red-colored LED’s implies high or low voltage. The working current of Tsunami capacitor is 20 volt or 24 at volt rise. Its terminals have a 1/10-gauge nickel plated, higher current terminal blocks along with 4-gauge reducers. The HCAP-5 includes one positive, one negative input, and a pair of positive, and two negative outputs.

In conclusion, regardless of whether you need a car capacitor or otherwise, are clarified by how much power you need for your car audio system. If it needs too much power then it will likely be starving your cars additional electric gadgets which will result to low performance. If you have a sophisticated car audio system that needs additional power, then it’s time for you to get the Tsunami HCAP-5 Capacitor.

Car Satellite TV and Its Benefits

Watching TV will never be exactly the same as it was before with the satellite television. A satellite dish or a receiver gets signals from satellites in orbiting in space, they transmit the signals to the satellite TV. It uses sophisticated technological innovation, which removes the requirements for wires and cables, so that the TV reception is much clearer, even sharper, and obviously far more reputable.

Nowadays, most people have satellite dishes on their households, but the utilization of this engineering won’t cease there. Cellular Satellite Television continues to be around for a while, but its efficiency and its convenience to automobiles wasn’t great back then. Before, you had to carry a large bulky satellite dish for boats, recreational automobiles and buses. But technology continues to change for the better. Equipping us with a new compact and low profile antenna introduced to the market place, auto satellite Television is now a big deal in the TV mobile industry because of its easy use.

Watching television when driving is serious and even dangerous most especially when you’re the one driving the car. It may even be illegal in some areas. There would be no problem if you’re the passenger you would have no worries in watching on the car satellite TV. The question you might consider is “what does the Car satellite TV profit me when I’m driving?”

Here are some points to consider having a car satellite TV. It will come in handy when you have kids distracting you the whole time. Wouldn’t you want to consider having one when the kids are screaming and shouting, horsing around, playing and fighting? The kids will be so bored and make their own way to entertain themselves and trust me you will not have a peaceful road trip I’ll tell you that much. Having a Satellite car TV is like having a lot of candy for your kids; it keeps them quite and happy.

When you have a satellite TV set up inside your vehicle it will make miracles happen. Your kids will be quite and will be sitting calmly and well behaved. They will be left to observe their preferred programs and favorite shows or movies. Consequently, they will be more occupied and are silently focused on the TV. It is also more pleasant for them, in comparison to just sitting all-around your car being bored to death. It won’t matter what your kids would like to see cartoons, motion pictures, children’s applications, or whatever floats their boat; you will find yourself in a peaceful state while you drive.

Thank the creators of this great technology. Even when you are in motion you still can watch the TV shows clearly and without delay. As long as you’re in the country or in the area where the signal can be transmitted you will be privileged to enjoy having the Satellite TV in your car working properly. You can find plenty of satellites orbiting the earth ready to deliver signals for the receiver. What a great technology that helps us keep on being entertained throughout the whole road trip not having the experience of being killed by boredom.

GPS Navigation Systems for Your Cars and Its Benefits

The Technology inside Navigation Systems for Cars

When you are looking for the best GPS systems features, remember to select the ones that have at least a couple of this features:

• Top view for the map
• Top view for the map with the map rotating with the automobile
• Bird’s eye view for the map or the next curve
• Linear gauge for distance, which is redundant if a rotating map is used
• Numbers for distance
• Schematic pictograms
• Voice prompts (Audible driving directions)
• Text to speech
• Real time traffic updates
• Internet connectivity
• Bluetooth

You may also want to know that the Road database is a vector map of some area of interest, where street names or numbers and houses numbers are encoded as geographic coordinates so that the user can find some desired destination by street address. The map formats are almost uniformly proprietary, although NAVTEQ are currently trying to address this with S-dal that is a royalty free map format released in the hope that it would become an industry standard for GPS navigation devices.

The LCD screens on some GPS navigation devices can also be used to display television broadcasts or DVD movies. A few navigation systems integrate with mobile phones for hands free talking and sms messaging.

Navigation systems for cars can include personal information management for meeting, which can be combined with traffic and public transport information system.

Other Navigation Systems for Cars Functions

If you thought that navigation devices were only for cars, here we are going to show you some other GPS systems functions.

GPS systems and Golf Carts: Golf Carts may have integrated rangefinders tailored to specific golf courses, providing interactive course maps and live readings of distance measurements to the green.

Advanced car security vehicle tracking systems can relay the vehicle’s location via cellular phone services in case of lost or theft. The technology can also be used to manage fleets vehicle’s, in which case it’s known as automatic vehicle location.

Some systems feature internet connectivity, either via Bluetooth to a mobile phone (in which case the device can typically also be used for hands free calling), or with a built in GSM SIM card. This connectivity can be used for up to date traffic information, to fuel prices, as well as to search for local distances. Such features are included in the Garmin Nuvi 3790T, The Motorola motonav TN765t, and the TomTom XL 340 S.
