Checks and trouble shooting 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.
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.
Engine troubleshooting
– Refer to the engine’s operator manual for the
engine troubleshooting. An extensive Engine
troubleshooting manual is available at Volvo
Penta. For more information contact Volvo Penta.
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).
