First let me say sorry because I do not speak English properly.I  know this question has been answered several times but I have no choice but to insist.

I have read many times all the solutions on how to start the engines of C130. Also I've seen several videos on youtube. Despite this and always following the same steps I get it sometimes but not others.

For this, I ask:
1 .- To start in cold and dark, you can tell me all the steps you follow to turn off  the cessna (avionics, batteries, alternators, magnetos, mixture)?.
2 .- Can anyone give me step by step, the method to be followed (with  battery or with external power) to turn on the engines?.

Thanks for reading my request.

If anyone can send me a detailed personal manual, my email is amembrives@ono.com
