Hi Martin, It sounds like you don't actually have the aircraft powered. Do you have both batteries engaged? And are you using ground power. If memory serves, if using ground power the middle button on the electrics part of the overhead panel should be in the down (GND) position. I hope this helps! James

Do you hear the fans+sounds go on when you turn them on? The EFIS displays do take a bit of time to warm up..but can't remember havn't J41'ed it up in a bit.
