MikeOH Posted June 7, 2023 Report Posted June 7, 2023 Did the just start, or have you always had the whine? One diode in the alternator may have failed. 2
rotorman Posted June 11, 2023 Report Posted June 11, 2023 I used to have a loud whine in my headset. Then I read someplace that cleaning up the master switch may help. I did it and the whine is gone.
