battery switch to this breaker. From this breakers
the power goes to the Helm Accessory Switches
at the Helm. All power to the Helm Switches can
be turned ON and OFF at this breaker.
Main Battery 1 - The DC Power comes from the
battery switch to this breaker. From this breaker
the power goes to all breakers directly below
this breaker. All power to the left hand column
of breakers can be turned ON and OFF from

Activating the DC Power
There are two (2) sets of switches that must be ON
to activate the DC Power on your 33C. One set of
switches are the battery switches located by the
entry door in the Salon. The other set of switches
are the Main Breakers on the AC/DC Panel. On the
DC section of the AC/DC Panel are two columns of
breakers. Each Main Breaker controls that column
of switches below it. To supply power to one of the
switches listed on the left side of the panel, the Main
Breaker on the left hand side must be on.
Fuel fumes in the engine compartment can ex-
plode. Before working on any electrical wiring,
ventilate the engine compartment and disconnect
the batteries to prevent sparking.
