switch to supply
120V AC
power to circuit breakers on the
right side.
The 120V AC panel has reverse polarity indicators. If an AC
supply is wired incorrectly, either aboard the boat or shore side, a
dangerous shock situation could exist. If the reverse polarity lights are
illuminated, disconnect that source of power and engage a qualified
marine electrician and notify the marina dock master if in a slip.

Pre-Start Check List
The daily pre-start checklist for the generator diesel
engine is similar to the main engines.
1. Close seacock, clean the sea strainer (the cap should be hand
tightened) and reopen the seacock.
2. Check the coolant. Remove the front panel. The manifold should be
full to the cap and the bottle should have coolant in it. You should be
able to see some coolant in the clear overflow bottle.
3. Check that the oil level is within the waffled area on the stick. Always
add the same viscosity of oil that is in the crankcase.
4. Look to see that there are no loose belts or wires and that there is no
oil or fuel in the pan under the
GENERATOR.
Don’t remove the coolant cap from a hot engine.
To Start
Turn
on
the
GENERATOR BATTERY
switch at the upper right of the
12V DC
panel. Push both
SLIDING INTERLOCKS up
on the 120V
AC panel
and turn
on
the
GENERATOR
breaker at the left side of the
120V AC panel
to
connect the left side of the panel to generator power. Turn on the
TRANSFER SWITCH
to provide generator power to the right side of the
120V AC panel.
1. Press the
PRE-HEAT
switch for 5-10 seconds to pre-heat glow plugs
before attempting start-up. Holding the switch too long can burn out
glow plugs.
2. Continue to hold the
PRE-HEAT switch
while you press and hold the top
part of the
GENERATOR CONTROL START
switch for 2-3 seconds until
the engine is going. That allows oil pressure to build beyond shutdown
set point.
3. After engine is going, release switch. The light at the switch glows red
when the engine is running. Let it run for 2-3 minutes before adding
loads.
Don’t crank starter more than 10 seconds. If the engine doesn’t start, be
sure that it stops completely before trying to start again
.
Excessive cranking
with water lift muffler systems can cause engine damage. If the engine
doesn’t start after three 10-second cranks, stop and refer to the procedure
on page 13 of the
Northern Lights Operator’s Manual .
Keep the GENERATOR BATTERY switch
on
while the generator is running
so its alternator will charge its battery. (Without a load on the alternator, the
battery-charging regulator could be damaged.) Also, keep the
GENERATOR breaker
on
while the generator is running. (It is not good for a
diesel engine to run for an extended period with no load.)
