The evolution of the motor industry has seen the introduction of complex electrical systems in the car. Most cars today rely on a start button that relies on electricity to start and stop its engine. Your car's electrical system is important as it controls the windows, mirrors, AC, and infotainment system.
Over time, your car may develop electrical issues, which are challenging to troubleshoot, especially without the necessary tools. Here is a guide to help troubleshoot and fix common car electrical problems.
Checking the Battery
A dead or dying battery is one of the most common car electrical problems. This issue can cause the car not to start, dimmed headlights, or other electrical components not to work. You need a voltmeter to troubleshoot the problems with your battery. A reading below 12 Volts shows that your battery is dead or dying.
Testing the Alternator
The alternator is one of the most important components in your car's electrical system. It's responsible for charging the battery while the engine is running hence needs to be frequently checked, especially when the battery keeps dying on you. You need to connect a voltmeter to the battery to check if it's operating optimally. A reading below 13 volts could mean an issue with the alternator, hence a visit to the auto shop.
Check the Car's Wiring
Another common car electrical problem is the car's wiring. If the battery and alternator are functioning, the issues could be your wiring. This is the most difficult problem to diagnose due to the complex nature of electrical wiring.
During an inspection, the mechanic will check for melted insulation or use a multimeter to check for continuity.
A professional runs all these diagnoses to ascertain the extent of the damage to your electrical system before advising you on the best course of action.
