The procedure is out of the manuals, its name is "semi-automatic procedure".
Sure lot of gentlemen are aware of this.
I had a few times to start engine with less than 23V battery. I was lucky that I only had several unfamiliar CAS messages, but didn't have DUs black out. I heard DUs black out happened in the situation.
Could you let me know the way called "semi-automatic procedure".
