7) Faulty start relay
8) Cold motor
9) Other causes
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
1) Intervention of circuit breaker
(thermoprotection)
2) Faulty thermoprotection
3) Faulty alternator
Possible cause

Solution
1) Verify start-up procedure in
the Operating Manual
2) Refill or top off
3) Replace
4) Refill the tank. Open the fuel
tap
5) Clean

eventually replace
6) Activate,
recharge,
replace the battery
7) Replace
8) Hold down the CHOKE
button, after start-up, for a
longer period of time
9) Consult the motor Operating
Manual.
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 intervention is
due to a faulty ground current
in the load or connection
cable. Find and remove the
fault.
3) Replace
1) Check total power supplied
by generator; if greater than
the power reported on the
specification nameplate,
decrease the load
2) Replace
3) Check
rotating
windings,
excitation capacitor.
