[Mgs] Two 12 volt batteries

[Paul Hunt]

I can't see that happening unless one of the batteries was nearly short or 
the system was barely charging.  At anything over 12.8v (normal charging 
voltage is 14.5v) both batteries will be charging.  The problem occurs while 
parked - if one battery is even slightly leaky it will drain both itself and 
the good battery connected to it.
