PROBLEM DIAGNOSIS
• Connect the AC supply cord securely to a live AC outlet.
• Double check the outlet to ensure it is working by connecting a known good piece
of equipment with the outlet.
• Inspect the DC output wires and connections to be sure they are in good working
condition.
• Refer to LED Flash Codes below if all 3 LEDs are flashing.
• Replace charger if everything else is correct.
Charger does
not turn ON
The AC plug must be disconnected and reconnected to start the charger once it
has turned-off from a charge cycle.
• Check the battery and charger connection and correct
• The output may not be connected to the batteries
• The connections to the batteries may have corroded or loosened.
• The output may be shorted due to improper connection to the batteries or pinched
wires.
• The output may be connected in reverse polarity to the batteries.
The charger will not be damaged by any of these problems.
All 3 LEDs blink
ONCE
simultaneously
Output connection error.
• Check the AC input voltage. The charger is indicating the AC voltage is too
low or too high.
This is an unusual problem and would most likely occur with a very
poorly regulated engine-generator set providing the AC voltage to the
charger.
All 3 LEDs blink
TWICE
simultaneously
AC input voltage tolerance beyond limit.
• No action required. When the charger cools, charging will restart
automatically.
• Check and correct for dirt or other debris on charger that may be reducing
cooling.
All 3 LEDs blink
THREE TIMES
simultaneously
Charger is overheated.
• No action required, charger will correct and restart automatically.
All 3 LEDs blink
FOUR TIMES
simultaneously
Input or output over current.
Troubleshooting Battery Charger (continued)
• Batteries are weak, old, or have one or more bad cells. Batteries will still
charge but capacity will be reduced. Replace batteries.
• Battery pack too large for charger. Use higher output charger or unplug
then plug-in charger to restart charge cycle to complete charging.
100% LED
blinks while
50% and 75%
LEDs are “OFF”
The 18 hour timer has elapsed and stopped charging. Batteries are unable to
complete constant current and constant voltage charge cycle.
