CAUTION
Do not use a scoop or weedless scoop-type through-hull fitting as a means of supplying raw
water to the generator. Water pressure against this type fitting, while the vessel is under way,
can push raw water past the raw water pump's impeller into the generator's exhaust system,
filling it and the engine's cylinders as well. Aush-type, clear, through-hull fittings are recom-
mended and should be located on the hull so as to
be
below the waterline during all angles
of boat operation.
NOTE:
Raw water entry into the engine cylinders is a warranty issue with the installer, not the
Westerbeke Corporation
The use of common-type street elbows is not recommended for plumbing the raw water circuit. These
generally have very restrictive inside diameters. Machined fittings
with
true inside diameters are preferred.
Electrical System
The electrical system should be checked to make sure all wires and harnesses are properly tied down with
clamps or plastic ties and that all wiring harnesses are supported at intervals close enough to prevent chafing
from vibration. Check to make sure all engine harness connections are tight and that they are made to the
appropriate terminals. Also, ensure that these terminals are not the recipients of bilge water or water from
leaky hatch covers or corrosion will result.
DC Electrical Connections
A tagged common ground stud for the negative (-) DC terminal connection is found at the bell housing of the
generator, next to the starter, in the form of a threaded grounding stud. The DC battery ground should be
connected at this stud.
Connect the battery's positive (
+ )
connection to the starter solenoid tagged for this connection.
CAUTION
To avoid an overcharging condition and a possible equipment failure, do not disconnect the
DC battery source while the engine is running.
Grounding
The generator set
must.
be grounded to comply with United States Coast Guard regulation 33 CFR-183 which
specifies that a common conductor
be
connected between the generator set and the vessel's main
propulsion engine's grounded starter motor circuit. This conductor (the common ground) prevents acciden-
tal passage of cranking current through fuel systems and smaller electrical conductors common to the
engines. This conductor
CD1.lSt
be the same size as the largest battery cable.
