4F: Electrical Systems, AC
The AC electrical system is controlled at the AC electrical panel. It has a metering
section, a 120-volt section, and a 230-volt section.
Note: The panel photographs are taken at an angle to reduce glare from the
light reflections on their high-gloss finishes.
4F1: AC Generator
The ship’s Onan Generator provides 9,000
watts of AC power to the vessel and is used for
battery charging, heating hot water, and operation of
incidental AC appliances.
The generator is in the engine room. Service
access is by unlatching and removing the forward
panel on the generator’s sound-shield cabinet.
More important is checking the sea strainer (see
4.44) to be sure is has not accumulated substantial
debris while the generator was run for extended
periods, particularly at anchor.
Starting the Generator:
1) press the “Start” button and hold until the engine starts.
This will take approximately 30 seconds (there is
no
separate “glow-plug” switch!) Only when it is started
and running should you release the switch.
2) Check the generator exhaust, or listen for it to confirm
that it is operating properly..
3) After a brief warmup of a minute or so, switch the shore
power switch in the AC power panel to “Ship Power”.
You should see the AC meters indicate there is voltage.
Stopping the Generator:
1) Switch the Shore Power switch to “Off”. This removes
the load for the generator and allows it to cool down.
2) After at least a minute to allow the generator to cool
down, press and hold the “Stop” switch on the
generator panel until the generator comes to a
complete stop.
Note: If the generator is not charging, check double pole switch on upper port side of
generator (forward is on).
