Specifications
3.
The black leads from the 12 volt distribution panel
labelled A must be connected to the negative
(-)
battery
terminal.
4.
If the boat
is
equipped with a battery charger,
connect the
red
leads labelled C1, C2, and C3 to the
positive
(+) terminals of batteries 1 & 2 (and the
generator battery if so equipped). Also, connect the
black ground wire C 1 to the negative (-) terminal of any
battery.

Operation
Power to the engines and all 12 volt electrical equip-
ment, except the automatic bilge pump and voltmeter,
is
controlled by the Battery Selector Switch.
Battery
Selector
Switch
Positions:
"OFF"
- With the Battery Selector Switch
in
the OFF
position, all 12 volt power to the boat is shut off except
for the bilge pumps and voltmeter. Always turn the
Battery Selector Switch to the OFF position when the
boat
is
unattended for an extended period.
"1"
- Position 1 will use battery
#1
to power both
engines and all
12
volt equipment. Battery #2 will be
isolated and remain
in
reserve. Battery
#1
will be
charged by the alternator(s).
"2"
- Position 2 will use battery #2. Except for automatic
bilge pumps and voltmeter, battery
#1
is isolated and
remains in reserve. Battery #2 will be charged by the
alternator(s) .
"ALL"
- With the Battery Selector Switch in the ALL
position, the batteries are connected in parallel. Both
batteries will be used by the engines and all 12 volt
equipment.
The use of one battery at a time
is
recommended. Use
one battery at a time by positioning the Battery Selector
Switch
to
either the
#1
or #2 position. Avoid using the
ALL position. Use the ALL position only when a single
battery is not capable of starting the engine(s).
Alternate battery usage increases battery longevity.
Use battery
#1
for the first day of a cruise and switch-
to battery #2 on the second day.
Monitor the voltmeter. Position the Battery Selector
Switch to the battery that has sufficient power to start
the engine(s). Start each engine independently; never
try to start both engines simultaneously. After the
engine(s) is operating, position the Battery Selector
Switch to the battery that has the lowest charge. This
will allow the
alternators to charge the low battery. Utilizing the
Battery Selector
Switch
in
this manner (instead of using
the ALL position) will supply a greater charge to the
battery.
FOR EXAMPLE:
If battery
#1
is
fully charged and
battery
#2
is in need of a charge, use battery
#1
to start
the engine(s). After the engine(s} are operating and
warmed-up, turn the Battery Selector Switch to the #2
position. This will permit the alternators to charge the
low, #2 battery.

3 BATTERY CARE & MAINTENANCE
Keep the batteries charged and filled to the proper level
with distilled water Keep the batteries clean, especially
the terminals and connection lugs. Be sure the batter-
ies are fastened securely while in use.
IMPORTANT: If a 120voltbatterycharger
is
used,
be
sure the 120 volt neutral lead of
lhe
charger is isolated
from the ground
or
bonding circuit. Be sure the battery
charger
is
of the type which properly senses battery
requirements and does not overcharge or cause the
electrolyte to boil.
Periodically inspect all electrical wiring to ensure clean
secure connections. Also, inspect for nicks, chaffing,
embrittlement, improper support, etc. Have any de-
fects corrected immediately by an experienced marine
electrician.

E - 4 VOLTMETER USE & OPE RATION
Voltmeters are provided to monitor the condition of the
batteries. Replenish a battery indicating a low charge.
Determinethe reason forthe discharge. Lack of battery
usage is as detrimental to battery longevity
as
is over
use. Alternate
batt~ry
usage is important.
When two batteries and a single Voltmeter are pro-
vided, a Voltmeter
Switch
is
supplied on the helm
control panel. When the engine(s)
is
not running and
the battery charger
is
off, depressing the Voltmeter
Switch towards position
#1
will indicate the voltage of
battery #1. Similarly, the voltage of battery #2 will be
indicated with the switch depressed towards #2. The
center position is off. When the Voltmeter
Switch is
employed during engine operation, the voltage of the
