POSSIBLE CAUSES
No AC power

Over temperature protection triggered
Severe over loading charger
Reverse polarity connection
Bad battery connection
Battery type select switch in wrong setting
Battery capacity too large
Ambient temperature too low
Battery has damaged cell or battery is too
old
Wrong battery type selection eg. charge
gel battery with Calcium-Calcium OR Wet
type selection
Total battery capacity is too high for dual
charging
Battery temperature too high
Battery is defective
A load is connected to battery and charger
is not in power supply mode.
The connected load is too large, using
most of the current from the charger.
Wrong battery type selection
Battery is excessively depleted and the
soft charging is triggered
Battery temperature too high
SUGGESTED SOLUTION
Check AC connections are correct
Replace with correct AC fuse by qualified
electrician
Check DC connections between charger
and battery
Check air intake vent at bottom of charger
is blocked or not. Check charger ambient
ventilation .
Check battery AH capacity within
recommended range
Check for correct polarity, replace car
blade fuse (7)
Check for loose contact, right cable size,
cable integrity
Recheck battery type and change to
correct battery selection
Make sure charger rating matches battery
capacity see table (B2)
Move battery to a room temperature
location, or get an optional temperature
sensor
Replace battery
Check charged battery label and change
battery type selection to correct setting.
Check battery capacity or charge battery
separately
Use temperature sensor (optional
accessory)
Replace battery
Change charger Selector Switch (2) to
Power Supply Mode.
Reduce the load to about 50% of the
charger's rating current Or take away the
load and set Charger to Battery Charger
Mode to fully charge the battery before
return back to the power supply setting
and load connection.
Check charged battery label and change
battery type selection to correct setting.
Recharge the battery after a day, if bulk
light remains after several hours, the
battery is most likely damaged and cannot
accept charge. Replace battery.
