Thanks to all who responded to my battery questions—this list is incredible!
Between the responses and some YouTube videos I ‘think’ I now understand my
system, which was installed and recommended by a pretty smart boat mechanic.
I must still confirm that both the switch/acr/charger are wired properly but I
now understand how the set-up works:
The acr does its thing automatically distributing charge from whatever source
to the isolated start and house batteries—I get it.
The switch with only OFF/ON/COMBINE positions is left always in ON position
which (this needs confirmed!) ALWAYS has batteries separated electrically. When
I start the engine, current is drawn from the start battery only. When I turn
on anything else on board, current is drawn from the house batteries only.
If something happens so that my start battery will not turn the engine over, I
can switch to COMBINE and hopefully get it started using all batteries/hands on
deck!
Following suggestions from listers (thanks again!), I will add a fused buss to
the house bank with suitable connectors/fuses to hook-up the output of my solar
MPPT and a portable emergency battery system in an attempt to thwart Murphy
when he inevitably shows up!

PS: Feel free to point out any errors in the above. My knowledge of practical
electricity is a lot wider than it is deep!
