Other Engine Faults
Symptom
Cause and Remedy
Has the miniature circuit
breaker (MCB) tripped or pop-
out breaker tripped.
•
Before resetting disconnect all equipment plugged into the sockets.
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.
•
Connect another piece of electrical equipment that is not faulty to
con
fi
rm that the generator is faulty.
•
Suspect a major fault with the alternator or its voltage regulation unit.
