Schumacher SE-70MA - Manual (Page 17)

• 13 •
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
Short or no start cycle
when cranking engine.
Drawing more than the
Engine Start Rate.
Failure to wait 4 minutes
(240 seconds) between
cranks.
Clips 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.
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 4 minutes of rest
time before the next crank
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, charge for 10 to
15 minutes in the highest
manual rate to help assist in
cranking.
BEFORE RETURNING FOR REPAIRS 16.
When a charging problem arises, make certain that the battery is capable 16.1
of accepting a normal charge. Use a good battery to double check all
connections, AC outlet for a full 120-volts, charger clips for correct polarity and
the quality of the connections from the cables to the clips and from the clips to
the battery system. The clips must be clean.
When a battery is very cold, partially charged or sulfated, it will not draw
16.2
the full rated amperes from the charger. It is both dangerous and damaging
to a battery to force higher amperage into it than it can effectively use in
recharging.
When an UNKNOWN OPERATING PROBLEM arises, please read the
16.3
complete manual and call the customer service number for information that will
usually eliminate the need for return.
If the above solutions do not eliminate the problem or for information about troubleshooting
or replacement parts, call toll-free from anywhere in the U.S.A.
