6 Checks and trouble
shooting
6.1 Checks
6.1.1 Checking voltmeter P4
– Put a voltmeter in parallel with voltmeter P4 on
the control panel.
– Check that the read-out of both voltmeters is the
same.
– Stop the generator and disconnect one terminal.
– Check that the internal resistance of the voltmeter
is high.
6.1.2 Checking ammeters P1, P2 and
P3
– Measure the outgoing current during the load, by
means of a clamp-on probe.
– Compare the measured current with the current
indicated on ammeter. Both readings should be
the same.
6.2 Engine troubleshooting
The table below gives an overview of the possible
engine problems and their possible causes.
The starter motor turns the engine too slowly
– Battery capacity too low.
– Bad electrical connection.
– Fault in starter motor.
– Wrong grade of lubricating oil.
The engine does not start or is difficult to start
– Starter motor turns engine too slowly.
– Fuel tank empty.
– Fault in fuel control solenoid.
– Restriction in a fuel pipe.
– Fault in fuel lift pump.
– Dirty fuel filter element.
– Air in fuel system.
– Fault in atomisers.
– Cold start system used incorrectly.
– Fault in cold start system.
– Restriction in fuel tank vent.
– Wrong type or grade of fuel used.
– Restriction in exhaust pipe.
Never perform a test run with
connected power cables. Never
touch an electrical connector
without a voltage check.
When a failure occurs, always
report what you experienced before,
during and after the failure.
Information with regard to the load
(type, size, power factor, etc.),
vibrations, exhaust gas colour,
insulation check, odours, output
voltage, leaks and damaged parts,
ambient temperature, daily and
normal maintenance and altitude
might be helpful to quickly locate
the problem. Also report any
information regarding the humidity
and location of the generator (e.g.
close to sea).
