PROBLEM
POSSIBLE CAUSE
SOLUTION
Engine start does
not work.
Drawing more than 100 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.
Crank time varies with the amount
of current drawn. If cranking draws
more than 100 amps, crank time
may be less than 5 seconds.
When the countdown from 180 to
0 is displayed, wait until the display
shows “
rdy
” for the next crank.
The thermal protector may have
tripped and needs a little longer
to reset. Make sure the charger
vents are not blocked. Wait and try
again.
On a severely discharged battery,
use the
30A Boost rate for 10
to 15 minutes, to help assist in
cranking.
I cannot select a 6V or
12V setting.
The charger is equipped
with Auto Voltage Detection,
which automatically detects
the voltage and charges the
battery.
No problem; this is normal.
I press the display
button, but do not
see the percentage of
charge.
When first connected to a
battery, the display shows
voltage only.
This is normal. The percentage
of charge is only displayed during
charging.
The display shows
“
bAD
/
bAt
/
F01
”.
The battery voltage is still
below 10V (for a 12V battery)
or 5V (for a 6V battery) after 2
hours of charging.
The battery may be defective. Make
sure there are no loads on the
battery. If there are, remove them.
If there are none, have the battery
checked or replaced.
The display shows
“
bAD
/
bAt
/
F02
”.
Desulfation was unsuccessful,
after 10 hours.
The battery may be defective. Have
battery checked or replaced.
The display shows
“
bAD
/
bAt
/
F05
”.
Lack of progress is detected
after 12 hours in Maintain mode.
The battery won’t hold a charge.
May be caused by a drain on the
battery or the battery could be bad.
Make sure there are no loads on the
battery. If there are remove them.
If there are none, have the battery
checked or replaced.
