Jaguar and Land Rover Alternators

While your vehicle’s ignition depends on electricity from the battery and spark plugs to start, it’s actually your alternator that produces the electricity that various systems, parts, and accessories rely on for power.

How Your Alternator Works

The engine’s crankshaft moves a belt that’s attached to a pulley located on the rotor shaft. As the rotor shaft rotates, magnetic coils inside get agitated. That causes them to produce a magnetic field, which is captured as AC power by a rectifier. The rectifier converts that into DC power that’s used by your battery, electronics, power windows, wipers, and more.

How to Spot a Failing Alternator

Sadly, even the best alternator can go bad. That sometimes happens with little-to-no warning, so you need to be alert to the signs of trouble before you find yourself stranded on the side of the road. These include:

• Dimming or flickering headlights
• Trouble operating your power windows
• Sound system issues
• A whining noise coming from engine
• A burning smell coming from under the hood
• Your battery repeatedly dies

Genuine OEM Alternators Are Best for Your Vehicle

If you’re having any of these problems, test your charging system. If the battery’s voltage reads low, give it a good charge. If it still reads below 12.5 volts after that, your alternator is likely failing. Replacing it with a new one made by your manufacturer is the right choice, since you’ll be installing one that’s guaranteed to fit right into place and perform as intended.
