Reasons Behind Electrical Issues in Cars
2
The electrical system of your car is very
important because it not only starts the car but
also provides power to many other important parts
of your vehicle.
3
The basic components of the electrical system
are the battery, starter and alternator and the
battery provides the entire electrical current to
the vehicle before the vehicle is started.
4
Once the vehicle is running, the alternator takes
over and keeps the battery charged and the
electrical system working.
5
However, at times the electrical system of the
car malfunctions and affects the reliability of
the car. Here are the reasons behind it.
6
Battery malfunctions
7
If the vehicle does not start or even try to turn
over, then the problem lies with the battery of
the car.
8
Most cars are equipped with a battery warning
light that will illuminate if there is an issue
with the battery or one of the other electrical
system components.
9
In most of the cases a drained battery is due to
the lights being left on and over time batteries
will go bad and need to be replaced.
10
Corroded Battery Cables
11
The battery cables are responsible for
transferring the current from the battery to the
electrical components of the vehicle.
12
If the car fails to start, then it will make a
clicking sound or the radio and other electrical
components will not work which indicates the
cables could be the problem.
13
Corrosion can corrode the cable and the battery
terminals and in most of the cases battery cables
cannot be repaired and need to be replaced.
14
Failed Alternator
15
The alternator converts the power the crankshaft
is generating into electrical energy which in
turn charges the battery.
16
If the alternator is not able to produce enough
voltage, then the battery can go dead and in most
of the cases a failing alternator will trigger
the Battery light.
17
Moreover, if the alternator completely fails,
then the car will eventually stop running as the
battery is not being recharged.
18
Malfunctioning Voltage Regulator
19
The voltage regulator is connected to the
alternator and it controls the amount of voltage
the alternator sends to the battery.
20
If this component is malfunctioning, then the
alternator will not send the correct voltage to
the battery which will lead to severe issues.
21
Signs of a failing voltage regulator include the
battery light illuminating, dim lights, dashboard
lights that dim or flicker and the engine will
hesitate.
22
Conclusion
23
The electrical systems also play a major role in
the functioning of the safety systems of your car
like the headlight and the brake lights.
24
Whenever you come across any of these symptoms,
then take your car to an automotive repair shop
to fix the issue.
