M20 Ogler Posted September 25, 2021 Report Posted September 25, 2021 The turn and bank needle is always centered even when I’m a bank. Today While trouble shooting the stall horn I noticed the cannon plug on the back was only screwed on by one thread. So I tightened it up all the way but it still makes no sound when I turn the master on. Plane is grounded until I hang my air box so no flight testing Yet Quote
RLCarter Posted September 25, 2021 Report Posted September 25, 2021 Take the cannon plug apart and check the terminals, if it was about to come apart it’s possible the terminals have been arcing and now they’re crapped up 1 Quote
MikeOH Posted September 25, 2021 Report Posted September 25, 2021 I'd pull the cannon plug and check that you have power at the terminals. Quote
carusoam Posted September 28, 2021 Report Posted September 28, 2021 If you intend to fly in IMC… Be on the look-out for a replacement instrument for the TnB… TnBs are terrible for your health… so they replaced them with TCs… Which a certain Brand B pilot flying over NY found a way to demonstrate… TCs aren’t better enough for your health either… Back-up AIs are the best way to improve your long term health in IMC… PP thoughts only, not a health expert… Best regards, -a- Quote
Yetti Posted October 3, 2021 Report Posted October 3, 2021 Let's say you have a Mooney Turn Coordinator. They are both vacuum and electrically supplied. Quote
carusoam Posted October 5, 2021 Report Posted October 5, 2021 My 65C TnB was electric only… and made really nice grinding sounds during shut-down… that were deemed to be normal… at the instrument shop… -a- Quote
