With 25 HRS. on my generator the automatic transfer switch has started to Buzz, it use to have a soft HUM when the generator was running.
The shore power side of the switch is just makeing a soft HUM when pluged in.
Both side of the switch have 110 volts and are working ok. May be the fix is to just turn the volume up on the TV or the stereo?
