How can I fix the electrical system in my Vauxhall Zafira Life?

I recently purchased a used Vauxhall Zafira Life and have noticed some issues with the electrical system. The radio sometimes goes out and the lights flicker at times. What could be causing this and how can I fix it?

It sounds like you may have a faulty alternator. I would recommend taking your car to a trusted mechanic to have it checked and replaced if necessary.

Another possibility could be a loose battery connection. Check to make sure the battery is securely fastened and clean any corrosion that may be present.

It could also be an issue with the wiring. I suggest taking your car to a professional to have it inspected and repaired if needed.
