Hi
I made a flight over the water today. Half way me and my passenger notice what we tought was a alarm in the headset. . It was a high frequency that was beeping at a speed around twice per second. I look at my ELT, Co2 detector, my eis and everything was fine. Turn strobe and nav light off ... no change. It's really a new noise and it's not continous ( i have 250 hre myself on the aircraft)
Then i turn off my alternator and the sound stop but came back as soon as i turn it on. It was still charging, amp was showing 23 , voltage 14.6
The plane have 350hre. It's the stock alternator that was coming with the FWF of the rv-10 in 2005.
on the approach and landing, the frequency and the tone of the noise went down with the rpm but it's still there at idle.
could notice a hum in my headset for the first 2min after engine start but it was stoping by itself after. Not sure it'S the same kind of noise.
i think i will take the alternator off and have it rebuilt. Any Idea before i do this?
Thank You
