Battery Switches and TABS Unit

There are three “ON” - “OFF” battery switches located on the front of the TABS unit which is located behind

a hatch at the starboard rear of the cockpit. The switches are activated using special keys that are attached to

the unit. The port battery switch is labeled “Port” and activates the port engine, the starboard battery switch

is labeled “Starboard” and activates the starboard engine and the center battery switch is labeled “House” and

activates the 12-volt breaker panel in the helm storage compartment and all other 12-volt accessories. The

house battery switch key is different from the engine switch keys, allowing the house battery to be activated

without providing access to the engine starting batteries. Make sure that all three switches are activated

whenever the engines are running to ensure that all 12-volt accessories will operate when they are needed. Red

LED lights above each switch indicate that the switch is on. The top LED light will be lit when the engines

are running or when the parallel switch is engaged.

The TABS controls the charging of all three batteries whenever one or both of the engines is operating. When

one or both engines is started, the engine alternator(s) start to recharge the batteries. This charging current

passes through the TABS sensing circuit. This circuit senses the charge and switches relays to connect the

“House” battery in parallel with the engine batteries. Thus the charge from the engines is split between the

batteries with the lowest battery receiving the most charge. When the engines are turned off, the charging

stops and the sensing circuit turns off the relays, disconnecting the “House” battery from the engine starting

batteries, thereby automatically isolating the batteries from one another.

When in port or at anchor, the switch that supplies the port engine and the switch that supplies the starboard

engine should be off. Only the center battery switch that activates the “House” battery should be on. This

will keep the engine starting batteries in reserve for starting the engines. All three battery switches should

be in the “OFF” position when leaving the boat unattended.

Current is supplied to the automatic float switch for the bilge pump when the batteries are connected

and the battery switches are off.

THE BOAT SHOULD NOT BE OPERATED ON A CONTINUOUS BASIS WITH THE EMER-

GENCY PARALLEL SWITCH IN THE "ON" POSITION.

4.4 12-Volt DC Switch Panels

The main accessory switch panels are located at the helm. The circuit breakers that protect the accessories

are located on the helm below the switches.

The following are descriptions of the accessories controlled by the main accessory switch panel:

HELM PANELS

Fuel Gauge Switch

The fuel gauge switch panel is located at the helm and allows one fuel gauge to be used for both fuel tanks.

With the ignition switch on, move the switch to port and the gauge will show the fuel level in the port fuel

tank. Move the switch to starboard and the gauge will show the fuel level in the starboard tank.
