If you’re suspecting that your Volkswagen Jetta’s alternator has problems, you should immediately take it to the nearby auto service center so that the mechanic can identify and repair the problem promptly.

2. What’s An
Alternator?

3. It’s an important part of
your car’s charging
system.

4. Its mechanism allows it
to convert the rotational
energy of the engine into
electric energy.

5. By recharging your car
battery, it fulfills the
following objectives;
• Energize the starter, ignition,
and fuel delivery system
• Power the lights, radio, and
other electric accessories

6. How Does An
Alternator
Work?

7. It’s a kind of DC
generator that works on
the principle of
electromagnetic
induction.

8. It has the following major
components;
• Pulley
• Rotor assembly and stator
• Rectifier
• Voltage regulator

9. Its pulley is linked to the
engine’s crankshaft via a
drive belt.

10. As the crankshaft
rotates, so does the
alternator pulley and
rotor assembly.

11. Distortion in the
magnetic field due to
that rotation will
generate alternating
electric current.

12. The rectifier then
converts AC power to DC
and feeds it to the
battery.

13. In the absence of a
properly functioning
alternator, your
Volkswagen Jetta’s
battery can starve to
death.

14. So, you should learn to
recognize the signs of
alternator failure in your
car.

15. By identifying the
alternator problem, you
can repair or replace it at
the very beginning.

16. Car
Alternator
Problems-
What’s
Causing It?

17. Some of the plausible
explanations for alternator
failure in Volkswagen Jetta are
as below;
• Bad wiring
• Blown fuse
• Faulty pulley or belt
• Improper installation
• Using unsuitable one

18. What
Happens
When An
Alternator
Fails?

19. When your Volkswagen
Jetta’s alternator goes
bad, you might
encounter some of the
following signs.

20. • A properly
functioning alternator
essentially keeps your
car battery fully
recharged.
• However, a faulty
alternator won't be
able to keep up with
the energy demand of
the battery.
• As a result of which,
your Volkswagen
battery might drain
completely.

21. • The faulty alternator
sign most drivers
recognize is trouble
starting the engine.
• So, if your Volkswagen
Jetta hesitates to start,
there’s a good chance
its alternator has gone
bad.

22. • This is by far the most
noticeable symptom
of a bad alternator.
• All you have to do is to
replace that loose belt.
• It usually means the
drive belt that
connects the
alternator pulley with
the crankshaft is
loose.

23. • Is your Volkswagen’s
battery light
illuminating?
• Therefore, check if the
alternator is working
properly or not, if
damaged get it
replaced.
• If so, it signals a
charging system issue
in your car.

24. • It's the alternator that
energizes the lights
and other electrical
appliances of your
Volkswagen Jetta.
• If anything bad happens
to the alternator, the
lights might flicker.

25. Wrapping Up

26. The alternator
essentially supplies
necessary electric energy
to your car’s electric
system.

27. Malfunctions in such a
key part can bring your
Volkswagen Jetta to a
halt in the middle of the
road.

28. For that reason, if you're
spotting any of the
above-said signs, call
your mechanic
immediately.
