Genuine Toyota Alternators

The alternator in your Toyota vehicle is part of its charging system. It takes the engine's mechanical energy and turns it into electrical energy, producing the electricity that your vehicle's systems and accessories rely upon.

How Your Alternator Works

It's pretty straightforward, frankly. Your engine runs belts that move a pulley. The pulley rotates a rotor shaft, which spins magnetic coils. That movement creates a magnetic field. The energy of that field is collected by a rectifier as AC power and then converted to DC power. Finally, a voltage regulator manages that power and delivers it to your battery, entertainment, power windows, wipers, and more.

Sadly, though, your alternator can go bad. When it does, it puts an immediate strain on your battery to continue feeding the electricity you need. That can quickly drain your battery and leave you stranded.

How to Spot a Failing Alternator

Signs of alternator trouble include:

• Your headlights begin to flicker or get dim
• The radio acts up
