Common Auto Electrical Problems
The complexity of your vehicle’s electrical system is immense, and any breakdown of its components can cause the entire system to shut down.
The auto electrical components that most often need to be repaired are the starter, alternator, battery and wiring. A diagnosis of your car’s electrical system will be needed to find out the non-functioning component. Let’s take a look at the purpose of each, how it can breakdown, and how it can be fixed.
Starter – The car starter, well, starts your car! When you stick the key in the ignition, the starter then turns the flywheel, which turns the crankshaft, which starts the engine. Possible causes of an inoperative starter are mechanical wear, failure of electrical connections or cables, or a weak battery. Depending on the diagnostics, car starter repair may be required, or replaced altogether if necessary.
Alternator –The alternator (named after “alternating current” A/C) recharges the battery, providing the electric energy needed for the proper operation of the vehicle’s electric and electronic systems. Most malfunctions of the alternator will be indicated by a warning light on the instrument panel, and may result in the car not starting or remain running. Alternator repair is possible, but replacement is usually required for a failed alternator.
Battery – The battery supplies the necessary electrical energy to crank the engine. A diagnostic will show whether the battery is indeed dead, or if there is another issue within the car’s electrical system. Replacement is required in the event of a dead battery.
Wiring – Wiring is found everywhere in the electrical system, within each component, and connecting each component. Failed wiring can give the false appearance of failed electrical components. Depending on its location and condition, wiring can often be repaired or replaced.
