Jeep Genuine Mopar Alternators

An alternator is a major component of a car’s charging system as it generates electricity from mechanical energy. This car part charges the car battery as you drive while also supplying additional power to the various electrical systems of your Jeep. JeepsAreUs offers 100% authentic alternator replacements for select Jeep models and model years at discounted prices.

Generate Power for Your Jeep Using Alternators

An alternator is a car generator and is one of the key components of the charging system of a vehicle. This generator is usually bolted to the engine and runs using a drive belt. Most car alternators are considered as maintenance-free units, with some lasting for up to 10 to 15 years without needing repairs. Consequently, your car can still run using its remaining battery power should its charging system fails to work.

Faulty alternators can cause a series of problems for your vehicle. Other than the battery-shaped warning light staying open even after starting your engine, this generator eventually charges poorly, causing your headlights or dash lights to dim and brighten once the engine is revved. It can also be caused by a failing battery, a poor connection with the battery terminals, or a loose serpentine belt that causes the generator to charge slower than usual.

Frequently Asked Questions: Alternator

How does an alternator work?

Car alternators convert mechanical energy into electrical energy. It has a pulley with a drive belt powered by your engine to move the rotor shaft. The shaft spins a set of magnets around a coil, producing an alternating current (AC). The alternator’s rectifier gets that power and turns it into DC power for your auto electrical systems.

How long does an alternator last?

Alternators will usually last for seven years or around 150,000 miles, depending on the recommendation of your manufacturer. However, particular factors can affect its longevity, including:

• The quality of your current alternator

• The overall condition of your car

• The number of electronic components in your vehicle

How can I tell if my vehicle’s alternator is bad?

A faulty alternator can make your car hard to start or prevent it from staying on for longer periods. Other symptoms of a failing alternator include:

• Dim or glaring lights

• A dead battery

• Slow or malfunctioning accessories

• Hard starts and engine stalling

• A rumbling or humming engine

• The smell of burning rubber or wires

• An illuminated battery warning light

How do I test an alternator?

You can perform either a headlight or battery test to see if your alternator needs replacing:

• Headlight test - Start your car, then turn on your headlights. Set your vehicle to park and press on the accelerator.

• Battery test - Open your hood and start your car, then disconnect your battery’s negative cable.

How long does it take to replace an alternator?

If you’re installing a new alternator yourself, you can finish the task in about two hours. But if you hire a mechanic for a complete alternator replacement, it might take you a whole day before you can get your vehicle back from the auto repair shop.
