orion 2 backlights

[Rhsmd1]

I was doing  my first non training, non instant mission.(ag-64) It started at a farp. cold start. My throttle back lights were not lighting up, but the on light was ok.

 i unplugged and repluged in the throttle/

 all lights came on. happened several times.

 I recall a message when logging out of sim app pro about the apu. never paid attention to it.

 Do the lights for the throttle base only come on when the apu is started up?
