8. TROUBLESHOOTING
FAULT
POSSIBLE CAUSE
REMEDY
No AC output - red LED
illuminated
DC input below 10Volts
Recharge or replace battery
Excessive load - thermal
shutdown
Reduce load - wait for
inverter to cool. Turn Off, then
turn On
No AC output
Inverter cold
Disconnect load from
inverter. Operate inverter
without load for a few
minutes. Reconnect load.
No AC output - Green LED
not illuminated
Inverter fuse blown
Remove fuses from their holders
and replace with those of the
same type and rating
Low battery alarm sounds
continuously
Bad wiring connections
Tighten all DC connections
Low battery alarm sounds
Low battery voltage
Recharge battery
Remove load from inverter
and recharge battery
Motorised power tool
won’t start
Excessive start-up load
If appliance does not start,
then appliance is drawing
excessive wattage and will
not work with inverter

Keep inverter and antenna
distant from each other. Use
shielded antenna cable.
Connect antenna to amplifier
Television/Radio
interference
Snow in picture, buzz in
speaker
9. FUSE REPLACEMENT
If the external fuse blows, then there is most likely a short or overload in the DC wiring. Find
and fix the problem before replacing the fuses. After fuse replacement, reconnect the
inverter, if fuse continues to blow, contact your Clarke dealer, or telephone Clarke

.
This power inverter is equipped with an external fuse. Normally, this fuse will not blow
unless there is a serious problem inside the unit. DO NOT open the unit, there are no user
serviceable parts inside the unit.
Motorised power tool
does not operate at
correct speed
Purely inductive load
Make the load not purely
inductive. Operate an
incandescent lamp at same
time as motor, ensuring the
combined load does not
exceed that of the inverter.
