The DC Electrical panel incorporates a Battery Select Switch and six DC
circuit breakers.
The Battery Select Switch provides a means of shutting off the main DC
power from the battery to the panel and engine. Or if two batteries
have been installed it can be used to couple the voltage of each battery
together to serve a particular task, usually engine starting.
CAUTION: DO NOT TURN BATTERY SELECTOR SWITCH TO OFF WHILE ENGINE IS
RUNNING. SERIOUS DAMAGE TO THE ALTERNATOR WILL RESULT.
A red PILOT light is provided on the panel. This light is illuminated
whenever the batteries are connected to the system and provides you with
an additional reminder that the batteries are on and also provides
enough light to read the switch panel labels at night. The pilot light
draws very little current and will not run the batteries down even when
left on for long periods of time.
There are several individual circuits provided on the D.C. POWER PANEL.
Each circuit is activated by a toggle switch and protected by a circuit
breaker. Before adding additional electrical equipment, check the
required rating of the circuit breaker. Also be certain the number and
size of the battery(s) is sufficient for the added loads.
A tripped circuit breaker is indicated by a raised white button. The
breaker is reset by first turning the toggle switch off and then
depressing the white button. Before attempting to reset a tripped
breaker, an effort should be made to find the cause of the overload, the
most common being a short circuit in one of the fixtures or wires, or
trying to operate too many devices on one circuit.
A.C. 110 VOLT SYSTEM (OPTIONAL)
The A.C. system operates on 115 volt, 60 cycle current. Power is
supplied from a 30 amp shore service by connecting the shore power cord
to the receptacle in the cockpit well. Make sure the main· circuit
breaker on the A.C. POWER PANEL is in the off position when connecting
the shore power cord.
IMMEDIATELY after connecting the shore power cable, check the 110 pilot
light. If it is on and the main breaker off, this indicates a live
circuit from the shore power receptacle. Next check the reverse
polarity indicator light. -If it is on, disconnect the shore power cable
IMMEDIATELY and determine the source of the problem as serious
electrical shock hazards may exist to persons on board or alongside your
yacht, even if the main circuit breaker is off. The ship's wiring has
been thoroughly checked and is of the proper polarity when it leaves the
factory. If the system has not been altered, the reverse polarity
condition is in the shore side system and should be brought to the
attention of the system operator. If the reverse polarity light does
not come on, the system is safe to operate. Turn on the MAIN CIRCUIT
BREAKER at the top of the panel and then select whichever branch circuit
is needed.
