Troubleshooting
PROBLEM
POSSIBLE CAUSE
SOLUTION
Charger will not turn
on when properly
connected.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
Check for open fuse or circuit breaker
supplying AC outlet.
Check power cord and extension cord for
loose fitting plug.
Have the battery checked.
Engine start does
not work.
Drawing more than the Engine Start rate.
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
the Engine Start rate, crank time may be
less than 5 seconds.
When the cool-down countdown from 180
to 1 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
Boost rate for 10 to 15 minutes, to help
assist in cranking.
