TROUBLE SHOOTING GUIDE
PROBLEM
POSSIBLE CAUSES
ACTION
1. No Output
120 VAC supply not con
-
nected
Connect power supply
Check AC distribution panel
for proper operation
External Fuses Blown
Check for Reverse Polarity
Replace Fuses with same
type and rating
Short Circuit
Trace Circuits for possible
fault
Unit has shutdown due
to overheating
Check air flow
Allow unit to cool
Unit has shutdown due
to over voltage (Also see
item 5 below)
Check input voltage
Converter will shut down if
the input voltage exceeds
13.2 Volts
Correct Input Voltage
2. External Fuses
Blown
Reverse Battery Hook
Up
Correct Hook up and replace
Fuses with same type and
rating
3. Converter cycles
on & off
Compartment gets too
hot
Check air flow to the con
-
verter
Improve Ventilation to the
compartment
4. Low Output
Excessive Load for
Converter
Reduce load requirements or
Install Larger Converter
Input Voltage not be-
tween 105-130 VAC
Correct input supply voltage
Bad Battery Cell(s)
Replace Battery
5. Intermittent or no
Output on Genera
-
tor, works on Shore
Power
Unit has shutdown due
to over 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 cuase the over
voltage protection to
shut the unit down
Contact generator manufac-
turer for possible defect in the
generator
