Starting engines with one low engine battery
If you’re not connected to shore power and if the
PORT ENGINE BATTERY is depleted and the PORT
ENGINE doesn’t start, start the STARBOARD ENGINE
to boost the STARBOARD
ENGINE BATTERY. With the STARBOARD ENGINE
ALTERNATOR now charging the STARBOARD ENGINE
BATTERY, as evidenced by voltage climbing, turn on
the emergency engine parallel switch located in the
starboard batter compartment. Then on deck, turn
the
PORT ENGINE IGNITION
switch on. Check to see
that the voltage on each engine display reads above
12 volts. If so, start the
PORT ENGINE
. After the
engine starts, turn off the
ENGINE EMERGENCY
PARALLEL
switch. After both engines are running,
start the generator to enable the charger/inverter to
start charging the batteries at a higher rate.
In the event both start batteries are discharged and
shore power is not available, turn on the emergency
engine parallel switch and attempt to start the
generator. The generator can start on as low as 9V.
Once the generator is running, ensure that the
charger/inverter is running and then turn off the
emergency engine parallel. The charger/inverter will
then start charging the house batteries and in turn,
both starting batteries. Wait several minutes until
both start batteries reach 12.5V and then start your
engines as normal
These procedures are for
emergencies. If a battery is low, determine the
cause. All 24-hour circuits are powered from the
house batteries. There are no residual loads
powered from the start batteries. See if there is a
charger or battery problem or if a device. If you are
at the dock, don’t leave until you diagnose and
correct the problem. If you are at anchor or
underway, you should return home or to a nearby
marina if you haven’t corrected the problem.
The Emergency parallel switch is located in the starboard
battery compartment

Most facilities won’t require information before hauling the boat with a Travelift or crane, but if they need
advice, refer to lift points on page 39 Boat Lift and Bunk Offsets, and Hauling Out and Blocking page 36.
Review the manuals in the accompanying binders, and in particular, refer to “Short Term Storage” and
“Long Term Storage” in the VPOM and consult the manuals for the
GENERATOR,
AIR CONDITIONING,
SEAKEEPER and WATER HEATER. Check manuals for all areas needing lubrication.
For the batteries, simply manually turn off all six battery switches in the battery compartments. The
automatic switches will require the user to push in on the knob to torn the switch to the "manual off"
position. This will completely isolate all batteries.
