ALTERNATORS
DESCRIPTION
Dual output and high output alternators are available as
optional equipment on most WESTERBEKE engines.
These
alternators can be installed during factory assembly or as
add-on equipment at anytime.
Dual alternators can be configured to charge two banks
of
batteries at the same time or, using a battery selector switch,
charge each set
of
batteries separately.
INSTALLATION

an optional dual alternator has already been factory
installed, simply follow the WESTERBEKE wiring diagram
