The answer to 'my generator won't turn on' is that there could be several common causes, including a dead battery, a fuel system issue, or a problem with the electrical components. Symptoms may include the generator not starting at all, starting but not running, or shutting off unexpectedly.
Some potential solutions you can try yourself include checking the battery connections and charge, inspecting the fuel lines and tank for clogs or leaks, and testing the spark plugs. However, if you're not comfortable working on the generator or the issue persists, it's best to call a professional electrical technician to diagnose and repair the problem.
