What is an Alternator?

The car alternator is a component similar to a dynamo that is located inside the engine compartment and which serves to power both the battery and the vehicle’s electrical system. The substantial difference between alternator and dynamo lies because the first produces alternating current, the second element direct current.

Thanks to the alternator, the battery, and all the other electrical components can receive the right amount of energy to start, and consequently allow the car to start correctly.

As seen above, the car’s alternator is like a dynamo. It means that it can take the electromechanical energy produced by the engines or propellers and then convert it into electrical power for the battery.

Its operation follows Faraday’s Law, also known as the law of electromagnetic induction. According to the production of an electromotive force, it is then possible to supply a particular flow of electrical energy to the components connected to the magnetic source, in this case, the alternator.

For functioning correctly, it always connects this piece to a belt. Ultimately, the alternator creates electromagnetic fields through which the energy is first transformed and then distributed towards the various components already mentioned.

Factors To Consider when shopping for the Best Car Alternator

1. Practical Parts

Like other parts of an alternator, starters are parts that wear out and need to be replaced after a certain period. The causes of failure can be many and are generally related to the natural wear of the mechanical parts. They make the alternator up of different components, the main ones being:

  • The alternator feet are used to secure it to the engine.
  • The pulley receives mechanical/kinetic energy from the motor through the motor ring gear.
  • The pulley rotates around the alternator axis.

The alternator has several connections: connection to the battery links to the starter (transmission of electrical energy, transferring the starting signal through excitation, etc.)

Alternators also include a regulator that regulates the voltage at which it recharges the battery. By decreasing the charge voltage, the regulator allows to increase of the charge current and, therefore, to recharge the battery faster.

2. Special Characteristics

Several characteristics can identify an alternator:

  • The distance between the fins: This dimension is relevant only when the alternator has two fins. It is an important parameter as it directly concerns the possibility of mounting the alternator on the engine.
  • The thickness of the fins
  • The overall length of the alternator
  • The diameter of the pulley
  • Center distance between holes
  • The number of grooves
  • The drilling diameter of the fins

3. Types of Alternators

There are often several types of alternator mountings depending on the vehicle you own. In order not to make a mistake when purchasing such a part, I suggest you check the following points:

  • The amperage of your original alternator
  • The shape of the connectors and their number
  • The general appearance and the arrangement of the fasteners
  • The number of splines at the pulley

By removing your old alternator, you can also, in most cases, observe a label stuck on it. These correspond to the original references. So you can no longer go wrong when purchasing your part.

4. Conditions of Alternators

Before purchasing, doing the test to find out if your alternator is out of order is relatively simple. All you need is an ammeter, a voltmeter, or a multimeter.

Once turned on, you must first connect your multimeter to the terminals of your battery using the two black and red-colored cables. You will need to measure the battery voltage in volts. If it is more significant than 12.2V, you can then test your alternator.

Then, when your engine is running at around 2000rpm, check the voltage displayed on your multimeter. If it is between 13.3V and 14.7V, then there is nothing abnormal to sign. However, if it is less than 13.3V, then the alternator must be replaced as it is at the end of its life.

Conversely, if the voltage exceeds 14.7V, it is essential to change the alternator regulator. It is no longer capable of limiting the supply of electricity. This surge could burn out your car accessories. If your vehicle has a stop and starts button, an alternator can display 15V or 16V, or just present 12V.

5. Alternator’s Power

The alternator produces a voltage-current of 13.5 V when idling and 14.5 V when speeding up. The one adapted to your vehicle. The wattage you should choose for your alternator is the one suitable for your battery. To find out, refer to your vehicle’s manual.

FAQs

Are Remy Alternators Good?

Remy alternators are highly desirable for a number of reasons. First, its maker has been one of the top brands in the market for some time, which speaks volumes about the quality of its products. The second factor is the overwhelmingly positive feedback it has received from clients and users, who continue to endorse it.

There may be many competitors on the market, but Remy alternators are an exceptional product.

Do You Know the Best Aftermarket Alternator?

Personally, you should know why inexpensive aftermarket alternators are a poor choice. Although aftermarket alternators are advertised as OEM replacements at a lower price, they are not necessarily suitable replacements because they are not similar to the OEM unit. Unless they are informed, purchasers are frequently unable to discern quality distinctions.

Some exceptions are the aftermarket alternators are manufactured by some well-known brands such as Bosch or Power Master.

Are Bosch Alternators Good?

Nothing much to say about this brand, right? Most users have good experience with Bosch alternators. The original equipment manufacturer (OEM) parts and replacement parts that Bosch sells are of such high quality that they should outlast the life of your vehicle. 

What are the best brands of alternators?

To identify the best brands of car alternators, just do a little research, and you will clarify many of your doubts. The best brands for a new car alternator are Bosch, Delco Remy, Denso, Magneti Marelli, Starline, and Valeo.

Besides the best brands, you will get to know the sites that are most reliable and offer the best service. The Internet is a potent tool in the hands of consumers. It is thanks to the feedback of consumers, which can be read online, that a particular company can achieve success or complete failure.

What is the price range of alternators?

The price range of this component can range from $50 to $400. It all depends on the car and the alternator it mounts.

What are the drawbacks of alternators?

The alternator is an engineering prodigy and is built with the aim of 100% yield. It means that the entire set of mechanical energy coming from the engine is then transformed into electrical power, with a loss in equal percentage terms at 0%.

Usually, it need not be replaced, as it is designed with the aim of not lasting forever, but still enough to power the car during the entire course of its use. Despite all this, the car alternator can shut down when it does not charge sufficiently.

When it happens, it is always tough to trace the causes. It is difficult to understand whether the fault is the battery or the alternator. Through tests, to understand which of the two components has failed, to study the performance of the alternator, it is necessary to disconnect the primary battery and connect with the cable’s secondary emergency battery.

After starting the car, you have to disconnect the battery terminals and see how the vehicle reacts. If it turns off, it means that the car alternator has failed. There is also another way to check the condition of this piece; a faulty alternator usually also produces annoying noises of a metallic nature.

And if the failure depends on the belt, then often a burnt rubber smell emerges that is very difficult not to smell. Ultimately, it is also good to check the headlights of the car, if the light is intermittent or dimmer than usual. It is highly likely that this may be because of the damaged alternator.
