Using 2 batt banks for the house is no longer considered good practice, as the larger combined bank suffers less from the electrical draw.

Using a rotary switch to combine the house and start banks for an emergency start is still good practice .

With one alt the start and house are combined , after engine start with a solenoid or an electric gadget.

A SOC meter is the only way to know State of Charge and keep the house batts happy.
