mooneyman Posted October 2, 2011 Report Posted October 2, 2011 When I got in my 74' F today and flipped the master switch there was a high pitch piercing sound that lasted for about 2 minutes. I flew a 100 mile trip without problems. Ammeter showed good voltage. All instruments worked fine. When I flipped master for trip home, high pitch piercing noise again for about 30 seconds. Never heard that before. Any ideas? Thanks
mooneyman Posted October 2, 2011 Author Report Posted October 2, 2011 Thanks! I am going to check it out tomorrow.
takair Posted October 2, 2011 Report Posted October 2, 2011 Gear horn? Do you have manual gear? Gear lights indicate down and locked when you turn on power?

DaV8or Posted October 3, 2011 Report Posted October 3, 2011 I'm guessing turn coordinator too. The fact that the sound goes away suggests that once the gyro spools up, the problem is silenced. Don't be surprised if you need a new one soon.
mooneyman Posted October 8, 2011 Author Report Posted October 8, 2011 Turns out it was a loose connection to the alarm horn of my digital clock. LOL! Cheapest fix of all possible scenarios!
