Your battery starts your Nissan, but your factory alternator makes startup possible in the first place. It's what charges your battery and runs your vehicle's electrical systems. It doesn't just power your dash display, headlights, and power windows, either. It also runs your windshield wipers, car radio, and power steering. It's even what warms your heated seats if you have them.
How Does an Alternator Work?
The answer is simple. It turns mechanical energy into electricity. The process is what's more complicated. It starts with your engine, which uses a drive belt to run a pulley that spins a rotor shaft in turn. That shaft rotates a set of magnetic coils, producing alternating current (AC power). A rectifier captures the power and turns it into direct current (DC power). Your vehicle then starts and stays running.
Signs of a Failing Alternator
Unfortunately, though, even an original alternator like Nissan makes can go bad eventually, often without warning. Besides age, the causes of a bad alternator can be anything from broken-down parts to bad jump-starts. You can even cause one yourself by installing incompatible accessories. Luckily, you can spot the symptoms of alternator failure easily. They include headlights flickering, a dysfunctional car radio, burning smells, engine whines, and even a dead battery. Electrical system shutdown is the worst sign. If you think your vehicle has alternator problems, run an inspection and a charging system test to be sure. When do you replace your alternator otherwise? Usually every 80,000 to 150,000 miles, or roughly every 7 years, but review your owner's manual for a schedule.
