Possible Causes/Solution
Alternator, AVR or wiring is damaged.
Contact Independent Authorized Servicing Dealer.
Generator output is shorted or severely overloaded. Identify
and clear the overload, and then restart.
Voltage supply to the AVR is high. If an external battery
charger is in use, contact installing dealer to correct
installation. If an external battery charger is NOT in use,
contact Independent Authorized Servicing Dealer.
Probable causes are:
1) The generator was temporarily overloaded.
2) The output was temporarily shorted. Try to restart the unit.
AVR is damaged. Contact Independent Authorized Servicing
Dealer.
Probable causes are:
1) Replace AVR filter. Inspect fan.
2) Intake or exhaust air path is blocked. Check intake and
exhaust.
3) The BIG fan is not running (only runs when the engine is
running). KEEP FINGERS AWAY FROM FAN HOUSING-
PERSONAL INJURY CAN OCCUR IF FAN IS RUNNING.
Contact Independent Authorized Servicing Dealer.
4) Air leak in AVR enclosure. Contact Independent Authorized
Servicing Dealer.
5) Engine running too hot. Inspect air intake and exhaust.
6) Ambient temperature has risen above 140º F (60° C).
Derate the generator output per specifications.
