equipped,
validation tests.
8.1
Check For Any Water Leaks
8.1.1 Reconnect the engine starting battery,
negative (--) lead last.
8.1.2 Reconnect power to the battery charger, if
equipped.
8.1.3 Start and run the generator set for
5 minutes to verify that there are no water
leaks from the newly installed seawater
flow switch and new/relocated seawater
pressure switch.
8.1.4 Shut down the generator set.
8.2
Seawater Flow Switch Validation Test
8.2.1 Remove one lead from the seawater
pressure switch.
8.2.2 Restart the generator set and run for
45 seconds.
8.2.3 Create a low seawater pressure condition
by closing the seacock. Verify that the
generator set shuts down on "Coolant
loss" after the applicable time delay. This

operation and wiring.
8.2.4 Reset the controller. See the operation
manual for reset procedure.
8.2.5 Reconnect the wire to the seawater
pressure switch that was removed in
Step 8.2.1.
8.3
Seawater Pressure Switch Validation Test
8.3.1 Pull the newly installed relay (P26) from its
base.
8.3.2 Start the generator set and run for
45 seconds.
8.3.3 Close the seacock.
generator set shuts down on "Coolant
loss" after the applicable time delay. This
test validates the low seawater pressure
switch operation and wiring.
8.3.4 Reset the controller. See the operation
manual for reset procedure.
8.3.5 Reinstall the relay (P26) to its base.
If either one of these validation tests do not yield the
desired results, verify proper wiring. If the wiring is
correct, replace the part that is failing the validation test.
8.4
If the seawater pressure switch and seawater flow
switch pass the validation tests, replace the sound
shield panels/doors, if equipped, using the
reverse procedure as outlined in Section 2.
8.5
After sound shield panels/doors are reinstalled,
start and run the generator set for 5 minutes. While
applying boat load verify proper operation of the
generator set.
If the generator set does not
operate correctly, determine the root cause and
correct. If the generator set operates properly,
return the generator set to service.
Note: See Section 9 for seawater flow switch
maintenance.
Note: Leave
the
(Section 9), service schedule (Section 10),
and wiring diagrams (Section 11) with the
owner for proper maintenance.
