Troubleshooting - Schumacher SC1591 Owner's Manual

CODE
The charger detected that the
F06 battery may be getting too hot
(thermal runaway).
The charger shut off because its
F07 internal temperature exceeds limit.
The battery voltage dropped too low
during the maintain mode.
F08
The internal lithium battery cannot
F12
be adequately charged.
If you get an error code, check the connections and settings and/or replace the battery.

Troubleshooting

PROBLEM
The charger will not turn on
when properly connected.
Short or no start cycle
when cranking engine.
DESCRIPTION
POSSIBLE CAUSE
AC outlet is dead.
Poor electrical connection.
Drawing more than the engine start
rate.
Failure to wait without cranking
during the regular 3 minute cool
down cycles.
Clamps are not making a good
connection.
AC cord and/or extension cord is
loose.
No power at receptacle.
The charger may be overheated.
Battery may be severely
discharged.
REASON/SOLUTION
The charger automatically shuts the current off if it detects
the battery may be getting too hot. Have the battery
checked or replaced.
Make sure the charger does not have the side ventilation
holes blocked. Move the charger out of the sun and into
the shade.
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.
The internal lithium battery is bad; have it replaced.
Check for open fuse or circuit breaker
supplying AC outlet.
Check power cord and extension cord
for loose fitting plug.
Crank time varies with the amount of
current drawn. If cranking draws more
than the engine start rate, crank time
may be less than 3 seconds.
Wait without cranking during the
3 minute cool down cycles, to allow the
battery and charger
to cool down.
Check for poor connection at battery
and frame.
Check power cord and extension cord
for loose fitting plug.
Check for open fuse or circuit breaker
supplying AC outlet.
The thermal protector may have tripped
and needs a little longer to close. Make
sure the charger vents are not blocked.
Wait and try again.
On a severely discharged battery,
use the boost setting for a few minutes
to help assist in cranking.
