With the STARBOARD ENGINE ALTERNATOR now
charging the STARBOARD ENGINE BATTERY, as
evidenced by voltage climbing, push the
PORT
ENGINE BATTERY
switch and the
ENGINE
EMERGENCY PARALLEL switch
on. 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.
The port ACR switch will need to be manually reset
because the voltage was below 10.8V. It will return
to normal automatic functions 10 minutes after
manual resetting.
Starting engines with two low engine batteries
If
you aren’t connected to shore power and if both
engines fail to start, start the
GENERATOR. (See
page 18.)
Ensure the
GENERATOR
breaker is on
and the
INVERTER
is set to
CHARGE. En
sure the
GENERATOR
is showing a charge on the voltage
display on the 12V DC breaker panel. Normally,
the
GENERATOR
would provide charging current to
both
HOUSE BATTERIES
and both
ENGINE
BATTERIES
. However, if the
ENGINE BATTERIES
have failed to start the engines, they have likely
dropped below 12.3V and tripped their ACR
switches so the
GENERATOR’S
charging current is
charging the
HOUSE BATTERIES
but current will not
flow to the
ENGINE BATTERIES
.
To reconnect the
HOUSE BATTERIES
to the
PORT
ENGINE BATTERY,
push the yellow button labeled
PORT ENGINE REMOTE SWITCH
on top of a small
black box located on the aft bulkhead under the
starboard pilothouse hatch (see adjacent
illustration). Then turn on the
PORT ENGINE
BATTERY
switch and up on deck turn on
the PORT
ENGINE IGNITION
switch. Check to see that the
voltage on the port
ENGINE CONTROL DISPLAY
is
reading above 12 volts. If so, start the
PORT
ENGINE
.
When it starts, check voltage and when adequate,
use the
ENGINE EMERGENCY PARALLEL
switch to
start the
STARBORD ENGINE
following the
procedure similar to the above paragraph, Starting
Engines With One Low Engine Battery . (However,
you will interchange the port and starboard
functions because you are starting the
PORT
ENGINE
first.)
Resetting the ACR switch
If the voltage on a
battery falls below 12.3V but not below 10.8V, the
ACR switch will open and separate the batteries.
When the voltage returns above 12.3V in either of
the batteries it will automatically reconnect and
share charge. However, If the voltage falls below
10.8V in either battery, the ACR switch will lock
open and will not reconnect the batteries even if
the voltage returns above 12.3V. You must reset it
manually by pushing the yellow button as
described above. It will return to normal automatic
function 10 minutes after manual resetting.
These procedures are for
emergencies. If a battery is low, determine the
cause. See if there is a charger or battery problem
or if a device or the
INVERTER
was left on. (Leaving
the INVERTER on over a period of a week or so
causes 95% of dead batteries.) 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 ACR switches are in the black housing under
the yellow buttons and are labeled PORT
ENGINE
REMOTE SWITCH
and STRBD
ENGINE REMOTE
SWITCH. They
are on the aft bulkhead in the
pilothouse starboard seat locker.

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 43
Boat Lift
and Bunk Offsets, and Hauling Out and Blocking
page 40.
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.
