The answer to 'why is my generator' is that there are several common reasons a generator may not be working properly. Potential issues include low fuel, a dead battery, clogged air filters, or a problem with the generator's electrical components.
If your generator won't start, first check the fuel level and ensure there is enough gas or diesel. Also inspect the battery and connections to make sure they are in good condition. Dirty air filters can restrict airflow and prevent the engine from running, so clean or replace the filters as needed. Electrical issues like a faulty alternator, wiring problems, or a malfunctioning control panel can also cause the generator to fail.
