You can determine the voltage level of each engine
battery by activating the battery's dedicated voltmeter.
These two voltmeters are grouped within each engine's
combined gauge at both the upper and optional lower
helms. For each engine, a single gauge provides infor-
mation on engine temperature, oil pressure, fuel tank
level, and battery voltage level. To activate each
engine's gauge, turn the engine’s ignition key one posi-
tion to the right.
NOTE: You do not need to start the engine to acti-
vate its gauge. Refer to the OEM information for
details on operating the engines.
"House" Battery Bank
You can determine the voltage level of the house battery
bank using the voltmeter located on the DC Control
Center. The DC Control Center is located in a cabinet
next to the salon entertainment center. When the
"house" battery bank master disconnect switch, the
Main One circuit breaker on the Safety Breaker Panel,
and the System DC Main circuit breaker on the DC
Control Center are "ON", the voltmeter indicates the
voltage level within the house battery bank. An amme-
ter, located next to the voltmeter, indicates the current
load on the DC electrical system.
If the voltage level in the "house" battery bank becomes
too low, recharge the battery bank by either running the
engines or suppling AC power to the boat. Refer to the
"Battery Charger 1" portion of Section 3 for more
information on charging the "house" battery bank.
While the engines are running, 12 volt equipment can
be used with little concern for excess battery discharge.
The power generated by the engine alternators is usu-
ally more than adequate to replace any power consumed
by 12 volt equipment.
However, without an engine running, a battery will
discharge as it powers 12 volt equipment. Operating 12
volt equipment without the engines running or the
battery charger functioning will eventually completely
discharge the battery. The condition of your batteries
can be monitored by referencing the engine voltmeters
and "house" battery voltmeter.
