Fault Finding
Engine Starts but then Stops
Symptom Cause and Remedy
Engine starts but then closes
down.
• Check control circuit fuse and MCB.
• Check battery charger circuit fuse.
• Check the 12V DC supply from the battery and battery charger has
not been lost.
• Suspect faulty control module. Swap it to check it.
Engine starts but then closes
down.
Common alarm on the control
module triggered.
• Check the fuel level and that the fuel system is not blocked or air
locked.
• Then check for faulty fuel level switch.
• Check oil level then check for faulty oil pressure switch.
• Check the fuel solenoid valve has not closed prematurely.
• Check the fuel system has not become contaminated or defective as
given previously.
Engine starts but then closes
down on Speed Fault on the
Control Module.
• Speed Fault - The most common cause of incorrect speed is air or
contamination in the fuel system. Bleed the system and try starting
again
Other Engine Faults
Symptom Cause and Remedy
Has the miniature circuit breaker
(MCB) tripped or pop-out breaker
tripped.
• Before resetting disconnect all load. Look for any obvious reasons or
faults as to why the equipment has caused the unit to trip.
Reset the MCB and reconnect and switch on equipment one piece
at a time. Do not hold the suspect equipment and use the selector
switch on the generator to turn the supply ON to the suspect equip-
ment. If a piece of equipment trips the MCB repeatedly make sure
it cannot be used again by removing the plug and labelling faulty/
unsafe.
The miniature circuit breakers
have not tripped.
• Suspect a major fault with the alternator or its voltage regulation unit.
No Electrical Output
Symptom Cause and Remedy
Check the electrical output
selector switch is set to the
correct position.
• For dual voltage generators ensure that the correct selection has
been made on the voltage selection switch.
Choose the correct setting.
• Set Main MCB to ON
Check the miniature circuit
breaker (MCB).
• Each 110V/230V output has its own MCB to prevent excessive
electrical load being taken through that socket. Check if the miniature
circuit breaker (MCB) has tripped or 2-pole circuit breakers have
been set to OFF.
