The answer to 'why is my generator not working' is that there could be several common causes, such as a dead battery, low fuel, clogged air filters, or a mechanical issue. Symptoms may include the generator not starting, running erratically, or not producing power.
First, check the basics like the fuel level, battery connections, and air filters. If those look good, the issue could be more complex, like a problem with the alternator, voltage regulator, or engine. In that case, it's best to call in a professional electrician or generator repair technician to diagnose and fix the problem.
