[C320-list] Battery Isolation

[jelliott at landspring.net]

I am in the process of modifying my electrical system, and am curious as
to how others electrically isolate the house bank from the starting
battery.

I have two 4D's under the settee paralleled as my house bank, and a
separate  starting battery located in the port lazarrette.  Both are
connected to independent channels of a Xantrax Truecharge 20.   The house
bank is monitored with a Link 10.

The banks are still not electrically isolated; I assume this is a result
of a common connection to the alternator?  How do others handled this?  I
understand there are battery isolators that do this?  Any advice on how to
"break" this return circuit (if that's the cause) would be appreciated.  I
am not very interested in adding a second switch which I know some have
done.

Thanks,

Julian
