Ford Alternators

The alternator in your Ford, Lincoln, or Mercury vehicle is a vital component in the charging system. What it does sound simple. It turns the mechanical energy generated by the engine into the electricity that feeds your battery, accessories, and various systems. How it does that is slightly more complex.

How Alternators Work

When the crankshaft transforms the pistons vertical motion into rotary motion, a belt attached to a pulley on the rotor shaft gets moved. That, in turn, spins magnetic coils inside the rotor shaft. The coils get agitated by the action and produce a magnetic field. That field is captured as AC power by a rectifier, before then getting converted into the DC power that charges your battery and fuels such parts as your electronics, power windows, wipers, and more.

Unfortunately, even the best alternator can eventually start to go bad. When that happens, you're at risk of getting stranded by the side of the road since your battery becomes the sole source of electricity -- and it will drain rapidly.
