6.3 Batteries & Battery Switches
There are three batteries and four battery switches
located in the battery switch panel. There is a
battery switch for each engine, a switch for house
accessory circuits and an emergency battery par-
allel switch. Battery switches are identified by
red knobs and the parallel switch knob is yellow.
The automatic battery isolator/relay (DVSR)
manages the charging current for the engine and
house batteries. Whenever the engines are run-
ning, the isolator/relay automatically senses the
condition of each battery and directs the available
current to the batteries that require charging.
The port and starboard engine batteries can be
temporarily connected in parallel by activating
the EMERGENCY PARALLEL switch to provide ad-
ditional starting current for each engine.
When in port or at anchor, the port and starboard
engine battery switches should be OFF. Only the
battery switch that activates the house and ac-
cessory circuits should be ON. This will keep both
engine starting batteries in reserve for starting the
engines. If the house battery becomes discharged
to the point that accessories stop operating prop-
erly, the engines can be started to recharge the
house battery.
Notice:
Current is supplied to the automatic float
switches for the bilge pumps when the
batteries are connected and the battery
switches are off.
Once the engines are running, the alternators
will charge each engine starting battery. As the
voltage in the batteries raises to a preset level,
the automatic isolator relay between the engine
batteries and house battery will close and direct
charging current to the house battery. The engine
starting and house batteries will continue to be
