For REPAIR OR RETURN, contact Customer Service at 1-800-621-5485. DO NOT SHIP
UNIT until you receive a RETURN MERCHANDISE AUTHORIZATION (RMA) number
from Customer Service at Schumacher Electric Corporation.
POSSIBLE CAUSE
The battery is sulfated.
Vehicle 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.
If these solutions do not eliminate the problem,
or for more information about troubleshooting,
contact customer service for assistance:
services@schumacherelectric.com

or call 1-800-621-5485
A sulfated battery may eventually
take a normal charge if left
connected. The charger will continue
to charge with a low current for up to
10 hours to recover the battery. If the
battery will not take a charge after 10
hours, have it checked.
Crank time varies with the amount
of current drawn. If cranking draws
more than the Engine Start rate,
crank time may be reduced.
When the
blinks, wait 3 minutes of rest time
before 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
minutes, to help assist in cranking.
