You are correct, I have two battery switches, a house bank switch and an engine battery switch. The house bank switch selects which bank powers the boat systems, the engine batt switch selects what powers the engine. Alternator charge can be directed to any or all banks through these switches as well.

Here is a separate battery wiring drawing and a battery operation/logic discussion from my owner's manual.


Battery switch logic
Kalina has five batteries connected in three banks controlled by two battery switches. The battery switches are located in the dinette, one forward and one aft. The forward switch controls two general use house banks and the aft switch controls a single engine starting battery. Refer to the battery wiring schematic, sheet E-1 in the appendix for further detail. Through these switches it is possible to isolate any of the three banks or combine them in any combination, either for use or charging.

House banks
House bank #1 consists of two group 27 lead acid deep cycle batteries located under the forward dinette seat. Turning the house battery switch to “1” connects this bank to Kalina’s electrical system for use and shore power charging. House bank #2 consists of two sealed AGM deep cycle batteries located beneath the starboard settee seat. Turning the house battery switch to “2” connects this bank to Kalina’s electrical system for use and shore power charging. Turning the house battery switch to “Both” connects both banks together for use and shore power charging.

Engine starting battery
The engine starting battery is a single group 24 lead acid battery located adjacent to the engine. Turning the engine battery switch to “1” connects this battery to the engine system. With the engine battery switch in this position no other batteries are connected to the engine system regardless of the position of the house bank switch and further, the engine starting battery is isolated from all other electrical systems.

Charging batteries from shore power
With the shore power connected, main AC breaker on and charger breaker on, the engine starting battery is automatically charged without regard to battery switch positions. The house batteries can be charged as individual banks or altogether. Selecting “1”, “2” or “Both” on the house battery switch determines where the charge is directed.

Charging batteries from running engine
After starting the engine on the isolated engine starting battery, the alternator output can be directed to any or all batteries. To recharge the engine starting battery only, leave the engine battery switch to “1”. To recharge the house banks, and in this order, select which house bank is to be charged with the house battery switch and turn the engine battery switch to “Both” or “2” WITHOUT SWITCHING THROUGH “Off”. With the engine battery switch on “Both” the engine battery is charged along with the selected house bank. With the engine switch on “2”, only the selected house bank is charged. With the engine battery switch on “2” and the house battery switch on “Off” there is no battery connected to the engine which is the same as switching the engine battery switch to “Off” with the same damaging result as described on page 4, item 15.

Battery management strategies
1. Never use the engine starting battery for general use power. Save it for starting the engine by keeping it isolated.
2. Batteries charge at a faster rate if they’re charged separately rather than altogether.
3. In the event of a low or discharged engine starting battery, the house banks can be used to start the engine by turning the engine battery switch to “2” and selecting which house bank is to be used with the house bank battery switch. Do not attempt to recharge the engine starting battery, it will not deep cycle and therefore must be replaced.
