[Rhodes22-list] Battery switch question: 1, 2 or both

[The Rhodes 22 Email List]

Yes, when it is in both, the current would pass back through the switch to
the other battery, but then the good battery would also be trying to charge
the dead battery.  It's like jumping a car.  If you connect a good battery
to a bad battery, it will drain the good one really fast.  That's why you
always have the engine running on the "good" car.
