When you turn the ignition key, you are
actually turning on the
which then cranks the engine. When a starter isn't working
correctly, the engine may start with great difficulty, or
not at all. Starter problems may be due to
failure, or outright breakage.
The alternator carries out two important tasks. It
recharges your battery while the vehicle is running to
keep it at peak starting power. The alternator also works
with your battery as a team to operate electrical
components, such as headlights, windshield wipers, and
more. A malfunctioning alternator can cause electrical
components to operate erratically, or even cause your
engine to suddenly stop running.
