Alex,
As far as the regulator is concerend, it's powered by the generator except
for a "sensing circuit", which draws about 1 mA at all times. Only when the
generator voltage exceeds the battery voltage is it switched on (SCR type
switch). There is also a reverse polarity sensing circuit, but it should
not use any current unless the diode is faulty.

There is a simplified schematic on page 33 in the Feb 2004 MVM issue.

If you are worried about maintaining your batteries, hook up a solargizer or
a "Chargetek 500" charger.

Have a great day!
