4F: Electrical Systems AC
4F1: AC Generator
The ship’s Westerbeke Generator provides 10,000
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 it
has not accumulated substantial debris while the
generator was run for extended periods, particularly
at anchor.
Starting the Generator:
1. Move the switch in the AC power panel to
“Start”
switch 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
cooling
water is being pumped from it.
3. After a brief warm-up of a minute or so, switch the shore
power switch in the AC power panel to “Gen”. 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 switch in the AC power panel toward
“Stop” u
ntil
the generator comes to a complete stop.
The generator is in the aft end of the engine room.
