THEORY OF OPERATION (Contd)
FUNCTION OF THE ELECTRICAL SYSTEM
The boat electrical system is 24 VDC: two sets of 12-volt batteries are connected in
series. Each engine has an alternator for charging the batteries. The circuits are
arranged so that either alternator charges both sets of batteries automatically.
Power is drawn from the batteries by two separate circuits. The batteries on the port
side power the starter motor of both engines and the port engine instruments. The
batteries on the starboard side power the starboard engine instruments and the
auxiliary circuits. If the emergency link pushbutton located on the auxiliary switch
panel, is depressed, starting and auxiliary batteries are connected in parallel.
