As one of Ireland's longest and most established providers of alternators, we have provided quality replacements for all types of vehicles. Inevitably our clients have many questions about these vehicle parts. This is understandable, of course. A replacement alternator is an investment; therefore, clients want to make sure they are paying for quality. For the peace of mind of all our clients, we have composed the blog below, which has complied with some of the more common questions regarding alternators. 

How much does an alternator cost?

The cost of an alternator can vary depending on the make and model of the vehicle, as well as the brand of the alternator itself. On average, the cost can range from €150 to €300 for a replacement alternator, but prices can be higher or lower depending on the specific circumstances. For example, in our online store, we stock the Ford Focus Petrol Alternator, which costs €151.25. While also having available the 24 Volt 5 Pin Marcedes Truck Alternator which costs €242.00.

What does an alternator do?

An alternator is a device in a vehicle that converts mechanical energy into electrical energy to charge the battery and power the vehicle's electrical systems while the engine is running. It works by using a rotor and stator to generate an alternating current (AC) which is then converted into direct current (DC) to charge the battery and power the vehicle's electrical systems, such as the headlights, radio, and air conditioning. The alternator also helps to regulate the voltage in the electrical system to ensure that it stays within a safe range.
In summary, the alternator is responsible for maintaining the charge of your car's battery while you drive, as well as powering all the electrical components of your vehicle.

How to test an alternator?

There are a few different ways to test an alternator, but the most common method is to use a multimeter, a tool that can measure electrical current, voltage, and resistance. Here are the basic steps to test an alternator using a multimeter:

Start the engine and let it idle.

Connect the multimeter's positive lead to the alternator's positive terminal, which is usually labelled "B+" or "BAT."

Connect the negative lead of the multimeter to the negative battery terminal.

Check the voltage reading on the multimeter. It should be between 13.5 and 14.5 volts, which indicates that the alternator is working correctly.

Next, you can check the alternator output by turning on all electrical loads in the vehicle, such as headlights, air conditioning, and radio and recheck the voltage. It should not drop below 13.5V.

If the voltage reading is too low or the alternator is not charging the battery, the alternator may be faulty and need to be replaced.

It's important to note that multimeter testing is just one way to check the alternator and is not the only way. A professional mechanic might have more advanced equipment to check the alternator. It's also important to use caution when working with electrical systems, as they can be dangerous if not handled properly.

What fuse controls the alternator?

In most vehicles, the alternator is controlled by a fuse that is located in the vehicle's main fuse box. The fuse that controls the alternator is typically labelled as "ALT" or "GEN" or something similar, and it is usually a high amperage fuse (40 to 80 amp).

In some vehicles, the alternator fuse is located in a separate fuse box, often called a "power distribution centre" or "under-hood fuse box." This separate fuse box is usually located near the battery or near the alternator itself.

It is essential to locate the correct fuse before attempting to test or replace it. If you're not sure where the alternator fuse is located, consult the vehicle's owner's manual or check with a qualified mechanic.

The alternator fuse is not the only fuse that is connected to the alternator; there could be other fuses or relays involved in the alternator's electrical circuit, and a professional mechanic might be able to help you identify them.

For decades, we have been supplying our clients with a massive and ever-changing range of starter motors. Start motors are an essential part of an engine. However, despite their importance, we still get many questions about these pieces of kit. Therefore, for your convenience, we have compiled some of these more common questions below.  

What is a Starter Motor?

A starter motor is an electric motor that is used to turn the engine of a vehicle over and start it. It is typically located near the flywheel or flexplate of the engine and is connected to the battery via a solenoid. When the key is turned, or the start button is pressed, the solenoid sends electrical power to the starter motor, which then turns the engine over. Once the engine starts running, the starter motor is disengaged, and the engine runs on its power. Starter motors are typically found in gasoline-powered vehicles and are not typically found in diesel-powered vehicles as they have a different starting system.

How much for a starter motor

The cost of a starter motor in Ireland can vary depending on the make and model of the vehicle, as well as the brand of the starter motor. However, on average, the cost of a starter motor in Ireland can range from €100 to €400. For example, on our online store, we sell the Pugeuot / Citroen HDI Starter Motor, which retails at €121.00 and the 24 Volt DAF 45/55 Starter Motor, which is available for €242.00. 

How do you know when a starter motor needs to be replaced?

There are several signs that a starter motor may need to be replaced, such as:
The engine cranks but does not start: If the starter motor is not functioning correctly, the engine will not receive the necessary power to start.
Strange noises: A failing starter motor may make odd noises such as grinding or whining.
Difficulty starting: If the starter motor fails, it may take longer than usual for the engine to start or not start.
Warning lights or messages: Some cars have warning lights or messages that will come on the dashboard if the starter motor is having problems.
It's always best to consult a professional mechanic to get a proper diagnosis and repair if you suspect your starter motor is not working correctly.

How long does it take to replace the starter motor?

The time it takes to replace a starter motor can vary depending on the make and model of the vehicle, as well as the skill level of the person doing the replacement. However, on average, replacing a starter motor can take anywhere from 1 to 2 hours.

It's important to note that replacing a starter motor usually involves removing other parts to access it, like exhaust systems, intake systems, transmission, and drive shafts. So, the time required could be longer depending on the location of the starter motor in the vehicle and the complexity of the task.
