Starting Batteries

[pattypape]

Don,

I have four 12V dual purpose, deep cycle/start marine batteries in
the left front bay ( anything dual purpose never does either very
well).
There is a big truck/bus start battery, I think it is called a 4D
or 8D in the right front bay, ( 970cca). All batteries are tied
together.

These batteries are about 3+ years old. They work OK, But, This
arrangement does not hold up very well for dry camping.
Next season I will replace all with 6 volt Trojans.

The gennie battery is isolated with its' with own alternator and
ability to charge from the battery charger.
The auxilary battery switch adds the gennie battery to the circuit
to help start the Cat or the gennie.
