Jeep Commander Alternators

An alternator is a main part of the charging system in your Jeep Commander. Without one, the SUV you love to drive wouldn't run at all. What it does is turn mechanical energy into electrical energy, AC current that gets converted to DC current and managed by a voltage regulator. It powers your vehicle's many systems.

How alternators work is simple. The process starts when the engine uses its serpentine and drive belts to turn a pulley. The pulley spins a rotor shaft, and the shaft rotates a set of coils, generating am magnetic field.

A rectifier captures the field's energy. It uses it to charge your SUV's battery, run its radio, dash lights and displays, plus power windows, steering, windshield wipers, and more. When an alternator goes bad, though, it often happens with no warning whatsoever, and for one or more of several reasons: installing incompatible accessories, jump-starting wrong, an overtightened alternator belt, or worn or damaged parts. There are a few signs you can look for, however. They include:

• An alternator or battery warning light on the dashboard
• Lighting malfunctions
• Car electronics problems
• A dead battery
• A burning smell near the battery or alternator
• Alternator fluid leaks
• A squeaking engine

Seeing any of them? Do a thorough inspection and charging system test. Otherwise, replace your every 7 years or every 80,000 to 150,000 miles, whichever comes first.
