The alternator keeps your Mustang's engine running and powers the electric accessories. Without a functioning alternator, the electrical components in your car wouldn't work. Most importantly, your battery wouldn’t charge, and your car wouldn't start. Luckily, installing a new alternator is pretty simple and affordable. And it's a useful upgrade for any generation of Mustang.
The earliest classic Mustangs used a generator instead of an alternator. Generator-to-alternator conversion kits make it easy to upgrade. Some vintage Mustangs might also have a broken or worn-out alternator. There are direct-fit replacements available and hardware to replace missing or rusty parts.
Even a modern Mustang can benefit from a new alternator. Replacing the factory unit with a high-output alternator will help power extra accessories.
