		  Knowing that I won't damage anything while cranking with the 

excitation current there, does a 3-position switch (so I can crank 

without excitation current) help with cranking ability?


	


    Yes . . . but by so small a value as to make

    it unobservable without precision measurements.

		    (I guess the same question goes for various other electrical 

 equipment/avionics; I know cranking with avionics ON won't hurt the 

 avionics, but will turning electrical equipment off during cranking 

 provide better cranking performance? I think we're talking 200 to 

 300 amps versus just a couple amps...maybe I have more issues if 

 those few extra amps are making a big difference.)


	


    A few percent reduction in battery load for

    cranking will have no significant impact on

    how well the engine starts.
