Genuine Acura Alternators

The alternator in your Acura vehicle is a primary part of its charging system. Without it, the luxury car or SUV you love driving wouldn't run at all.

Its job is to turn mechanical energy into electrical energy. The process starts with your engine. It runs serpentine and drive belts, a pulley, a rotor shaft, and a set of magnetic coils.

The movement of each coil creates a magnetic field -- put simply, it generates electricity, AC current that a rectifier converts into DC current. A voltage regulator manages the resulting charge. As a result, your car battery can run electrical systems like the car radio, dash lights and displays, power windows, power steering, windshield wipers, and more.

Alternators often fail because of damaged or degraded parts, a belt that's too tight, an incorrectly done jump-start, or an incompatible accessory install. Worse yet, failure usually happens without warning. Luckily, there are signs one is going bad.

Battery and alternator warning lights on the dashboard are one. Lighting and electronics malfunctions are another. Others yet include leaking alternator fluid, a squeaking engine, a dead battery, and a burning smell, usually near the battery or the alternator.

If you see any of these, run an inspection and charging system test and change your alternator if the results require it. Otherwise, when to replace one is straightforward: do it every 7 years or every 80,000 to 150,000 miles. Consult your owner's manual for more information on what to do.
