Light and avionics not work
-
Hello. I have a problem with Just Flight Piper Arrow 3 to MFS2020. when the airport loads, I cannot start the avionics, batteries 1 and 2 do not work. Landing lights also do not work. if I run the plane through the tablet the plane works but the lights don't work. if, on the other hand, he loads a lone running on the tarmac, then everything will be done. What could be wrong ?

Maybe the battery is dead? It should show the voltage on the EFB, and there is a button to recharge the battery if it gets too low
