Generator frequency fluctuation
WebIf you mean that the frequency fluctuates up and down, it could be that your engine needs a tune-up. If it's a small gasoline-powered generator, it could be that the carburetor is a little bit clogged, so it can't supply quite enough fuel under a heavy load. You might consider running some carburetor cleaner through it. WebDec 23, 2024 · To identify generator frequency fluctuation, listen carefully to the engine and monitor the control panel. If you hear a diesel engine struggling or hunting randomly, it is likely that this audible fluctuation is causing the generator's frequency to rise and fall erratically on the control panel.
