Re: Help figuring out this engine buzzer circuit
As the engine turns over the oil pump begins to pressurize the system. At some point the pressure will activate buzzer switch and go off. It may need replacement if it goes off too early (oil pressure too low). You would rather a warning that oil pressure is low, but not yet low enough to cause damage.
