14. BEFORE RETURNING FOR REPAIRS

If these solutions do not eliminate the problem, or for more information about troubleshooting, call:
Schumacher Electric Corporation Customer Service, 1-800-621-5485
Return products under warranty to your local NAPA Auto Parts Store.
POSSIBLE CAUSE
AC outlet is dead.
Poor electrical connection.
Battery is defective.
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.
Check for open fuse or circuit breaker
supplying AC outlet.
Check power cord and extension cord for
loose fitting plug.
Have the battery checked.
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.
