So, let me get this straight. You skipped the very first section of the check list which is titled "ENABLE ELECTRICAL POWER AND INTERCOM" and now you're confused as to why you have no electrical power?
Let me start by saying that Chapter 12 is not an idiot's guide to starting a KA-50. It's a very realistic and detailed start-up procedure that requires intricate systems knowledge to complete. For a beginner to just try to skim though it and cherry pick the systems they think they want to start-up is going to create serious problems. The check list is in the order it is in for a reason. Many systems are codependent on others. Starting up a random sequence of systems is going to end in failure to start the helicopter and frustration for the user.
If you're really in such a hurry to start your helicopter that you're willing to skip the entire first half of the check list why don't you just use the "Windows Key + Home" shortcut to auto start the helicopter? Barring that there are approximately an infinite number of videos on youtube demonstrating both abbreviated and full start-up procedures. That would be a good place to start if you just really don't want to read the manual. However, without reading the manual your lack of systems knowledge is going to cripple you in the sim.
BTW, I suggest watching every single video on this page http://forums.eagle.ru/showthread.php?t=32511
Even if you read the entire manual front to back these videos are very helpful.
