Ok, I am getting it.
So, the main bus, and basically everything in the B206, is powered first by the battery, then by the generator (ie. engine) once the engine is fired up and the generator is switched on (and working).
Is there anything you can't turn on with the engine off? (ie. that requires the generator is powering it)?
Also, can you at least turn on the panel lights (to see what you are doing) with the battery off?
Thanks a bunch guys,
Patrick
