I would have thought that starting the engine on with the alternator 

field powered would load the engine, not the alternator.


	


   Don't think anyone said it loaded the alternator.

   It's the battery that has to supply 3 or so amps

   alternator field excitation when the alternator

   is not spinning. Hence it is the battery that

   is 'loaded'.

 difference as to whether the engine started or not.


	


   The mechanical 'load' is not zero but it's so tiny

   a percentage of what's necessary to crank

   the engine that adding it to the mix is

   insignificant.
