Hi
I have a pure sine wave inverter for my car which is emitting a high pitched low voltage alarm, even though the supplied voltage (measured at the board) is >2V higher (12.6V) than the trigger voltage (10.5V). This happens whenever the car's engine is turned off. The unit continues to deliver adequate 240V to plugged appliances.
I would like to simply kill the component emitting the alarm audio, but don't know what it looks like.
Can anyone help me identify it?
Can I do this but keep the circuit board functional?
thanks
