The sense wire for the voltage regulator should then be taken to the battery side. Therefore both batteries see the same voltage drop and they will be charged equally. It is not a particularly elegant solution since there is a constant voltage drop in the system, dissipating significant power - hence the large heat sink. It works, though. Gary, Right - And before you get such a part, compare the Diode characteristics with that available from _http://www.periheliondesign.com/_ (http://www.periheliondesign.com/) Just as an intellectual exercise, of course.
