The answer to 'generator not working' is that there are several common causes, including a dead battery, issues with the fuel supply, problems with the electrical system, or mechanical failures. Symptoms may include the generator not starting, running erratically, or not producing power. Solutions can range from replacing the battery, cleaning the fuel system, or troubleshooting electrical components, to more complex repairs that may require a professional.
It's important to diagnose the specific issue before attempting any repairs. Some tasks, like changing the oil or air filter, may be suitable for a DIY approach. However, more complex problems, such as issues with the engine, alternator, or control panel, often require the expertise of a licensed and experienced generator repair technician.
