GTN750 suddenly goes black

[jetset]

Hi,

i just want to do a longer flight at FL 105 and after 10 minutes in flight the GTN750 went black. I have no failures activated and was not able to restart it. Any idea what happens?!

Looks like you've lost all electrical power, and your ammeter is showing a draining battery. Did you forget to activate your alternator?

@Black-Square To be honest not sure. I will try it again , same flight and will double check if the alernator ist active. Thx for your quick reply!

@Black-Square

Just to confirm you mean this one to on?

The main alternator is the rocker switch to the right of the battery master switch.
