The motor does not start up, or starts
up and then stops immediately
1) Engine switch a in the wrong positions
2) Lack of or insufcient oil in the motor
3) Faulty motor stopping device (oil-alert)
4) Lack of fuel in tank or fuel tap closed
5) Dirty or faulty spark plug
6) Cold motor
7) Other causes
1) Verify start-up procedure in the Operating Manual
2) Rell or top off
3) Replace
4) Rell the tank. Open the fuel tap
5) Clean or check and eventually replace
6) Hold the CHOKE control, after start-up, for a longer
period of time
7) Consult the motor Operating Manual.
Problem Possible cause Solution
Lack of tension to the AC sockets 1) G.F.I. switch in the OFF position
2) Intervention of G.F.I. switch due to faulty
ground current
3) Faulty G.F.I. switch
4) Intervention of circuit breaker (thermo-
protection)
5) Faulty thermoprotection
6) Faulty alternator
7) AVR fuse blown
8) Faulty AVR
1) Position to ON
2) Disconnect load from AC sockets.
Position the G.F.I. switch to ON; if the switch
intervenes once again, the fault is on board the
machine.
Contrarily, the cause of the G.F.I. switch interven-
tion is due to a faulty ground current in the load or
connection cable. Find and remove the fault.
3) Replace
4) Check total power supplied by generator; if gre-
ater than the power reported on the specication
nameplate, decrease the load
5) Replace
6) Check rotating diode windings, alternator excitation
capacitor.
See specifc alternator manual.
7) Check and replace
8) Check and replace
No-load output voltage too low or
too high
1) Incorrect motor speed
2) Faulty alternator
3) AVR out of calibration or fault
1) Set the motor's no-load speed
2) Check rotating diode windings, alternator excitation
capacitor.
See specifc alternator manual.
3) Adjust VOLT potentiometer of the AVR replace
1) Replace rotating diodes
2) Check total load and eventually decrease
3) Check the fuel supply circuit.
See Motor Operating manual.
4) Check and replace
1) Faulty alternator
2) Overload
3) Number of motor rpm too low
4) Faulty AVR
No-load voltage OK, too low with load
Lack of tension to the c.c. terminals 1) Thermoprotection intervention
2) Faulty thermoprotection
3) Faulty diode bridge rectier
4) Faulty alternator winding
1) Check the load current and eventually decrease it.
2) Replace
3) Replace
4) Replace
