INFINITI Alternators & Generators

INFINITI Alternators & Generators: Powering Your Electrical Systems

The INFINITI Canada parts team has all the parts you're looking for your restoration, modification, or repair project. Alternators generate electrical power to charge your battery and operate lights, ignition, fuel injection, and electronic systems while the engine runs. These electromagnetic devices convert mechanical energy from the engine into alternating current, which gets converted to direct current for your vehicle's use. When alternators fail, your battery drains quickly and electrical systems stop functioning.

How Alternators Generate Electrical Power

A pulley system connects the alternator to your engine's crankshaft, spinning an internal rotor surrounded by electromagnetic windings. This rotation creates alternating current that flows through internal diodes for conversion to direct current. The alternator produces voltage regulated electrical power that maintains battery charge and supplies current to all electrical components including the ignition system.

Signs Your Alternator Needs Replacement

Alternators typically last 80,000 to 120,000 miles before internal components wear out and charging capacity diminishes. You might notice dim headlights, slow engine cranking, or dashboard warning lights indicating charging system problems. Strange noises like grinding or whining from the alternator area suggest bearing failure or internal damage.

Why Choose Genuine INFINITI Alternators

Genuine INFINITI alternators are designed to provide exact amperage output and voltage regulation for your specific model's electrical requirements. Aftermarket alternatives may not deliver sufficient power for modern electronic systems or could produce voltage fluctuations that damage components. Popular models like the QX50 and Q50 depend on precise alternator specifications to support advanced infotainment and safety systems.
