No Output
120VAC supply not connected
Connect power supply
Check AC distribution panel for proper
operation
Reverse battery fuses blown (See
page 1 for location)
Check for reverse battery connection.
Replace fuses with same type and rating (See
page 2)
Short circuit Trace RV circuits for possible fault
Unit has shut down due to lower
voltage
Check input voltage
Correct input voltage
Low Output
Compartment gets too hot
Check air flow to the converter
Improve ventilation to the compartment
Excessive load for converter
Reduce load requirements or install larger
converter
Input voltage too low Correct input supply voltage
Bad battery cell(s) Replace battery
Intermittent or
no Output on
Generator, works
on Shore Power
Unit has shutdown due to lower
voltage.
Add another load to the generator, this may
reduce the “spikes” to an acceptable level
Some generators exhibit
excessive voltage spikes on the
AC power output, this may cause
the over voltage protection to
shut the unit down
Contact generator manufacturer for possible
defect in the generator
Open Fuse
Indicator lit
(See page 1 for
location)
Fuse open Replace fuse with same type and rating
