Hello everyone. I am new to the forum so if i placed the topic in the wrong forum, please forgive me. Hope someone would see this and help me. I just got and instaled the SCS Tupolev TU-134A-3. I did everything properly (batteries on, power selector, fuel pumps on etc. whatever necessary told in documents and tutorials) and i turned the "apu master" and "apu start" switches to on. actually at that time two lights should be illuminated; "apu inlet doors opened" and "apu is ready to start". The yellow "doors open" light illuminates but "ready to start" light doesn't so i couldn't start the apu and the whole aircraft either. Can anybody help me?
