Warning Lights: If any dashboard warning lights, such as the check engine light or battery light, are illuminated, it's a sign that your electrical system needs attention.

Starting Problems: If your vehicle is slow to start or doesn't start at all, it could be an issue with the battery, starter, or alternator.

Dimming Lights: Headlights or interior lights that dim or flicker, especially when idling, can indicate a problem with the electrical system.

Battery Issues: If your battery is more than three years old, it's a good idea to have it and the charging system checked. Look out for corrosion on battery terminals or a swollen battery case.

Electrical Component Failure: If you experience issues with power windows, locks, seats, or other electrical components, it's time for a check-up.

Strange Noises: Unusual noises such as clicking or grinding when starting the vehicle can be related to electrical problems.
