I dont believe that you will be successful trying to start your engine with
a 24 volt starter using a 12 volt battery.  Maybe when its cold but no-way
when its hot.

My solution would be to use two 12 volt batteries (in series) for starting
and charging, then tap off one of the batteries for my 12 volt circuits.
