The answer to 'why is my generator flickering lights' is that flickering or fluctuating lights can be a sign of an issue with your generator's voltage regulation. This can be caused by a few common problems, such as an overloaded generator, faulty voltage regulator, or loose electrical connections.
Flickering lights indicate that the generator's output voltage is not staying stable and consistent, which can damage sensitive electronics and appliances connected to the generator. To troubleshoot and fix this issue, you may need to check the generator's load capacity, inspect the voltage regulator, and ensure all electrical connections are tight and secure. If you're not comfortable doing this yourself, it's best to call in a licensed electrician who can properly diagnose and repair the problem.
