OEM Vehicle Alternators

The factory alternator in your SUV, truck, car, or van is a critical part of the charging system. What it does sounds involved, but it’s actually simple. It takes the mechanical energy of the engine and turns it into the electricity that feeds most of your vehicle’s systems and accessories.

How an Alternator Works

The crankshaft takes the pistons’ vertical motion and transforms it into rotary motion that moves a belt attached to a pulley located on the rotor shaft. As the shaft spins, coils inside get agitated and produce a magnetic field. A rectifier captures that field as AC power and converts it into DC power. A voltage regulator manages the resulting electricity, using it to charge the battery and power such parts as your windows, wipers, and electronics.

How to Spot Alternator Issues

Even the highest quality alternator can begin to fail, though. If that happens, you need to act quickly or else risk getting stranded once your battery drains. Signs of trouble include:

• Problems operating power windows
• Dimming or flickering headlights
• Sound system acts up
• Your battery keeps dying
• Weird engine noises
