ORANGE ERROR LED ILLUMINATES
If you have accidentally reversed the battery connections, POSITIVE to
NEGATIVE (and vice versa), an ERROR LED (Orange) will illuminate solid. If
you see the ERROR LED illuminated, you will need to clear the ERROR by
correcting the battery connections, POSITIVE to POSITIVE and NEGATIVE
to NEGATIVE. The ERROR LED is a visual diagnostic tool to inform you that
you have made the wrong battery connections. Accidentally connecting
to the battery in reverse polarity will not cause any damage to the battery
charger or battery. This safety feature is enabled even when the AC power
plug is unplugged.
BLINKING ERROR AND CHARGE LED ILLUMINATES
When the battery charger detects an ERROR condition, the ERROR LED and
CHARGE LEDs (25%, 50%, 75%, 100%) will blink. If you are seeing this
ERROR condition, it could be the result of one of the following situations:
• BATTERY VOLTAGE INCOMPATIBILITY
Check to make sure you have selected the correct charge mode for your
battery. For example, if you have a 12V battery, make sure you have selected
a 12V charge mode. If you have accidentally selected the wrong charge
mode, it could cause this ERROR condition. Select the appropriate charge
mode to resolve this ERROR condition.
• SULFATED, DAMAGED, OR POOR BATTERY
This ERROR condition can be the result of a sulfated, damaged, or poor
battery. To properly diagnose a sulfated, damaged, or poor battery, take
the battery to a local battery store for an evaluation. If you have checked
all other possible ERROR conditions and cannot clear the ERROR, it is
probably the result of a sulfated, damaged, or poor battery. For other
possible conditions of a sulfated, damaged, or poor battery, see the sections
entitled “CHARGE LEDs FULLY ILLUMINATE IMMEDIATELY” and “BATTERY
CHARGER MAKING A CLICKING SOUND” below.
• LOW VOLTAGE BATTERY
If the battery voltage is below 7.0VDC (12V) or 14.0VDC (24V), it could cause
this ERROR condition. See the section entitled “LOW VOLTAGE BATTERY”
below to resolve this ERROR condition.

NO LIGHTS COME ON WHEN THE BATTERY CHARGER IS PLUGGED
INTO AN ELECTRICAL OUTLET
BATTERY CHARGER STAYS IN STANDBY MODE AND WILL NOT CHANGE
MODES
If the battery charger stays in the STANDBY mode and will not change modes,
it could be the result of one of the following situations:
• HIGH VOLTAGE BATTERY
If the battery voltage is above 14.0VDC and you have selected 12V charge
mode, it could cause this ERROR condition. This ERROR will cause the
CHARGE LED and ERROR LED to blink continuously. To resolve this ERROR
condition, select 24V charge mode.
• ABNORMALITY PROTECTION
This ERROR condition is the result of the battery charger being in the Bulk
mode for more than 41 hours. This ERROR condition is the result of a bad
battery. To resolve this ERROR condition, take the battery to a local battery
store for an evaluation.
• POOR AC CONNECTION
Check if the AC outlet has power. If the AC outlet has no or limited power, it
could cause this ERROR condition. Plug a light into the AC outlet to check
if the outlet has power. If the light is extremely dim, this could be the result
of limited AC power. The battery charger is designed for use at 85-130VAC.
If there is no power or the power is below 85VAC, locate another AC outlet
that has sufficient power to resolve this ERROR condition.
• BLOWN FUSE IN BATTERY CONNECTOR HARNESS
Check the fuse in the battery connector harness. If the fuse in the battery
connector harness has blown, it could cause this ERROR condition. Replace
the fuse with a 40 amp automotive blade-type fuse to resolve this ERROR
condition.
• CORROSION ON BATTERY TERMINALS
Check the battery connections for battery corrosion. If battery corrosion is
present on the battery connections, it could cause this ERROR condition.
Remove the battery corrosion to resolve this ERROR condition.
• LOOSE BATTERY CONNECTIONS
Check the battery connections to the battery. If the battery connections are
loose, it could cause this ERROR condition. Tighten the battery connections
to resolve this ERROR condition.
