Proper glow plug function is indicated
by a vo~meter drop (figure 4.7.7) when
the PREHEAT switch is depressed. This
drop will be slight but discernible. If no
vo~age
drop is noted, tt may indicate
defective glow plugs or a
fau~
preheat
circutt (check for loose connections).

CAUTION

Prolonged cranking can damage the englnel
Prolonged cranking intervals wtthout the engine starting can
resu~
in
filling the engine mounted exhaust system wtth raw water coolant. This
may happen because the raw water pump is pumping raw water through
the raw water cooling system during cranking. This raw water can enter
the engine's cylinders by way of the exhaust manffold once the exhaust
system fills. Prevent this from happening by closing the raw water supply
through-hull shut-off, drain the exhaust muffler, and correct the cause
for the excessive engine cranking needed to obtain a start. Engine
damage resulting from this type of raw water entry is not a warrantable
issue; the owner/operator should keep this in mind.
Remote Starting Procedure
The remote Start/Stop panel (figure 4.2) has three switches that serve the same functions as
on the engine-mounted Start/Stop panel (figure 4.1). it has a green LED light and no gauges.
When starting at a remote location, the green LED comes on when the generator is running
at approximately 600 rpm. This indicates when the START switch can be released since the
starting of the generator may not be audible from the remote location.
A. When the preheat switch is depressed at the remote Start/Stop panel the LED light will
illuminate. When the start swttch is depressed and the starter cranks the engine this LED
light will dim. When the engine starts the LED light will brighten signaling to release the
START switch. Continue to hold the PREHEAT depressed for a few seconds to allow oil
pressure to build up and close the oil pressure safety switch that will be in the series
path for 12V B
+
to the fuel run solenoid
B. After the generator is started and the starter switch is released, the generator's starter will
not crank until someone again operates the PREHEAT swttch first because this switch
supplies voltage 10 the START swttch.
