I agree with 3top, leave the gene on always, I never touch it and was told by our engineers that it has somethink to do with a battery drainage problem.....
Disconnect it when away overnight or when not using the machine.
The pilot and co-pilots map lights are hot wired so be careful not to leave them on.
I have seen guys endorse pilots with the technique of starting by turning the throttle on similar to the 206. I have found that it just don't work right.
I don,t have the latest flight manual at hand but I generaly then direct the pilot to start with the throttle in the detent (or just slightly before is the best position just incase you need a quick shutoff).
the first set of nozzels fire it up well to around 300-350, but the second are a bit slow so you may need to give it a bit.....
As 3top says the turbine preferrs it (around 700) and you save the gene a bit.
With sarting with the throttle as I do you should have no problems even if the battery drops off.
Do you guys judge the health of the battery by the sound of the igniters aswell?.........you can usually pick it every time.
Good luck
