SOLUTION
Check for poor
connection to battery
or power supply.
Make sure connection
points are clean. Rock
clamps back and forth
for a better connection.
A blown fuse is
usually caused by
reverse polarity or
a short circuit within
the inverter.
To replace, contact
a qualified service
technician who will
diagnose the inverter
and replace the fuse(s)
with the appropriate
replacement(s).
