ENGINE FAULTS

Remove 3 Amp. fuse in the control panel
while working on the generator to prevent
the engine to start.

5.2.1 General

Most electrical problems relating to Voltage or Frequency
are due to wrong engine speed.
Note that RPM and Hz are basically the same.
Use the problem solving table to find the cause. When
there is no obvious cause one can adjust the RPM (refer
to special procedures).
When the engine is not cranking well, starting problems
almost always originate from battery problems or poor
battery cable connections.
When the engine is cranking, well starting problems
almost always originate from lack of fuel or air bubbles in
the fuel pipes.
When the engine does not start instantly,
prolonged cranking can fill up the exhaust

5.2.2 Trouble shooting check list engine

PROBLEM
Diesel engine fails to crank,
the starter makes clicking
noises, or the engine cranks
very slowly.
USA / WHISPER 3,5 / April 2004
If the generator is unable to supply enough
power to start an AC electric motor,
this is usually because this motor draws
too much current during starting.
CAUSE
Almost certainly this is an electrical problem Check on water in the cylinder and further
or the engine is locked by water in the
cylinder or there is other severe damage.
Display will indicate "low battery voltage"
• Starter battery switched "OF".
• Starter battery voltage insufficient
(battery too weak).
• Faulty fuse on control panel.
Check the electric motor's current draw required
for starting. This should not exceed the
rated generator peak output current. This could be
remedied by providing stronger capacitors to the
motor or using a "soft-start". Inquire at your
nearest Mastervolt dealer or directly at the
manufacturer, Mastervolt in the Netherlands.
system with cooling water because of the
water injected exhaust. When the water
enters the cylinder through the valves this
will bring severe damage to the engine.
When the engine does not start and
repeated cranking is necessary shut off the
seawater inlet. Open the valve immediately
after the engine has started.
A failure code is displayed whe a hardware faillure at the
generator is detected.

SOLUTION
damage by cranking while lifting the valves with
the decompression handle. When there is water
in the cylinder, then deactivate the control system,
disconnect the battery, remove the glow plug.
Crank the engine to remove the water through the
opening of the glow plug. Check oil on the presen-
ce of water and change oil. Find out how the
water entered the cylinder (check the air vent).
Take precautions to prevent it from happening
again. When there is no mechanical malfunction
the problem must be an electric malfunction.
Check position of the battery switch and switch
"ON".
Check battery voltage. Recharge the battery.
Inspect battery terminals and cables for a good
electrical connection (inspect against corrosion,
tattered wires, etc.)
Replace fuse.
