So my issue is that if I take a brand new jf17 cold and turn on the batterie or plug in the ground power, after around 10 minutes most systems inside will go haywire (mfcds, the warning pannels, the starter wont work anymore) and it leaves the jet unable to be used and need a repair
I have done a bunch of test including flying it before shutting down and keeping just the batterie or the GU on, either way at some point both will result in the same problems
after ending the flight/mission there is no reports of any damages to any system so I don't think it's an empty batterie (since GU does not help)
so the only I can stay on the parking space while waiting for people or to wait for an interception is to either keep its engine on and have to refuel and all just before take off or turn the batterie off and lose my alignment and other settings
I tried with random failures off and no changes
if anyone knows better or maybe its an unknown bug for the devs idk honestly.
Edit: so yeah it was overheating electronics
from so tests ive done it seems that after passing some cool air with the ecs does bring everything back to normal as its not permanent damages
