Electrical System
an expansion tank for the engine coolant mounted
near the generator. Make sure the fluid level in
the expansion tank is kept between the maximum
and minimum lines of the tank.
The seawater cooling system operates exactly
like the cooling system on the main engines. It
includes a strainer that prevents debris in the
seawater from entering the cooling pump. The
strainer is located near the generator. It is impor-
tant to check and clean the strainer regularly to
ensure the seawater system can circulate enough
water to provide cooling for the closed cooling
and exhaust systems on the generator. You
should also check the exhaust port for water flow
each time the generator is started. If there is no
discharge within thirty seconds, shut down the
generator and find and correct the problem.
Note: Generators consume DC electrical cur-
rent and charge the house / generator
battery just enough to compensate for
the DC electrical current the engine
requires to operate. Therefore, it is
important to activate the battery char-
ger to maintain the house and engine
batteries whenever the generator is
running.
Note: The generator may not be able to op-
erate all 120-volt accessories at the
same time. POWER MANAGEMENT
PRACTICES may need to be observed
depending on the AC power load.
Cleaning the Sea Strainers
• Turn off the engines and generator.
• Close the generator water intake valve.
• Open the top of the strainer and remove the
screen.
• Thoroughly flush the screen and the inside of
the strainer to remove foreign matter.
• Lubricate the seal.
• Reassemble the strainer making sure that all
fasteners are tight.
• Open the intake valve.
• Start the generator and inspect the strainer
for leaks.
