How to troubleshoot the electrical system in a Kia Sorento?

I'm having trouble with the electrical system in my Kia Sorento. The headlights and dashboard lights keep flickering. What could be causing this issue?

It's possible that you have a faulty alternator. Have it tested and replaced if necessary. You should also check the battery connections and make sure they are clean and tight. Loose connections can cause electrical issues.

Another possible cause is a defective voltage regulator. This component regulates the electrical charge from the alternator. If it malfunctions, it can cause fluctuations in the electrical system. Have a mechanic check it and replace it if needed.

You may also want to check the fuses and relays related to the headlights and dashboard lights. A blown fuse or faulty relay can also cause these issues.
