5 Trouble shooting guide
1. LOOSEN THE SCREW ON THE POSITIVE TERMINAL AND DISCONNECT THE POSITIVE WIRE. READ
THE CONVERTER OUTPUT VOLTAGE USING A DC VOLTMETER. IF THE VOLTAGE IS ABOVE
26 VOLTS, THE CONVERTER IS WORKING PROPERLY.
2. IF THE CONVERTER OUTPUT IS ZERO VOLTS, USE AN AC VOLTMETER TO CHECK FOR PROPER
VOLTAGE AT THE 120 VAC INLET, WHERE THE CHARGER IS PLUGGED IN. THIS VOLTAGE
SHOULD BE BETWEEN 105 AND 130 VOLTS.
3. CHECK THE FUSES LOCATED AT THE FRONT OF THE CONVERTER. THESE FUSES CAN BLOW IF
THE BATTERY OR DC OUTPUT LEADS HAVE BEEN CONNECTED IN REVERSE, EVEN FOR A
MOMENT, OR IF THE CHARGER DC CABLES OVERHEAT BECAUSE THEY ARE UNDERSIZED OR
IMPROPERLY CONNECTED. REPLACE THE FUSES AND REPEAT STEP 1.
4. IF THE PROBLEM PERSISTS, USE THE CHART BELOW.
PROBLEM
POSSIBLE CAUSES
ACTION
1. No Output
Not connected to 120 VAC source
Connect to an AC source
Check AC distribution panel source for a tripped
breaker
External Fuses Blown
Check cable for Reverse Polarity
Replace Fuses with same type and rating
Short Circuit
Trace AC 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
Charger will shut down if the input voltage exceeds
132 Volts AC
Correct Input Voltage
2. External Fuses
blown
Reverse Battery Hook-Up
Correct Hook-up and replace Fuses with same type
and rating
3. Charger cycles
on & off
Compartment gets too hot
Check air flow to the charger
Improve Ventilation to the compartment
4. Low Output
Excessive Load for Charger
Reduce load requirements or Install Larger Charger
Input Voltage not between 105-130 VAC
Correct input supply voltage
Bad Battery Cell(s)
Replace Battery
5. Intermittent or no
Output on
Generator, but
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 provides 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
