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 John Deere Penta. For more
information contact John Deere 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).
