Uhh ok got my answer today when I tried it....the 12V battery starts charging off the 14V battery but without anything to stop it from charging it just drains the 14V battery while gassing off the excess power.
Not a good idea for either battery.
So....guess I will just use my lawnmower SLA battery to keep the ECU alive while I charge at night - test and see if the mileage improvement is worth the hassle of a cleaner solution.
