A bit of a tech question for you.
S76C, when the number 1 engine is started (on battery) first, and then start the number 2 engine, all is well and everything starts fine.
If the number 2 engine is started first (again on battery) under the normal start prodcedure (generators on), the number 1 engine will not/is reluctent to start.
If you start the number 2 engine first, then deselect the generators, and then start the number 1 engine, it will start perfectly every time.
We cannot find any fault diagnosis charts etc in either the engine or airframe manuals which address this problem.
HELP!!!!
