Many malfunctions that occur in vehicles can be diagnosed as
automotive electrical problems. The source of these problems is usually related
to the electricity that is being generated by the battery or alternator. Each
of these car problems can typically be separated into one of several
categories.
Since the battery is the source of electricity for a
vehicle, it is no surprise that it is commonly a cause for many automotive
electrical problems. Usually the issue is a dead battery, caused when the
battery can no longer hold a charge. Sometimes a faulty component of the
vehicle can cause a dead battery. Other times it can be a result of leaving a
component like the headlights or stereo on for an extended period of time. This
problem can usually be remedied rather easily with either a jump-start or a
battery recharge. A car battery can also become damaged or simply too old and
in need of a replacement.
Another source of a common automotive electrical problem is
the vehicle's alternator. While an automobile is running, the alternator is
recharging the battery. Once the alternator breaks, the battery is quickly
drained and the vehicle loses power. Sometimes the alternator belt can also
wear out or become cracked, leading to a similar malfunction where the battery
easily becomes discharged.
Sometimes the source of an electrical problem in a vehicle
can be a broken electrical wire or a blown fuse. All of the electrical
components of a vehicle are attached to one another through the wires of the
electrical system. There are also many vehicle fuses in this wiring, which protect
sensitive automobile components from power surges. This is very convenient
since it is much less costly to replace a fuse than an expensive auto part.
Some of the most important electrical components are the
spark plugs and spark plug wires. When these go bad ,the engine will no longer
properly work. This problem can usually be detected when the car runs rough in
idle, accelerates poorly, stalls, or is getting bad gas mileage. Bad spark
plugs and wires can usually be remedied easily with a tune-up.
Another automotive electrical component that can cause car
problems when it goes bad in a solenoid. These magnetic coils are used to
distribute power to the starter and to provide the power to open automatic door
locks. A bad solenoid can easily be confused with a bad starter or a dead
battery, since any of these can cause the engine to not be able to turn over
when starting the car.
