PROBLEM POSSIBLE CAUSE SOLUTION
The charger is making an
audible clicking sound.
Circuit breaker is cycling.
Battery is defective.
Shorted battery cables or
clamps.
Severely discharged battery,
but otherwise in good
condition.
Reverse connections at
battery.
The settings may be wrong.
Check the charger settings.
Have the battery checked.
Circuit breaker cycles when
current draw is too high.
Check for shorted cables
or clamps and replace if
necessary.
The battery may not want to
accept a charge due to a run-
down state. Allow charging
to continue until battery has
a chance to recover and take
a charge. If more than 20
minutes, stop charging and
have the battery checked.
Shut the charger off and
correct the lead connections.
Charger will not turn on
when properly connected.
AC outlet is dead.
Poor electrical connection.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and
extension cord for loose fitting
plug.
The battery is connected
and the charger is on, but is
not charging.
Clamps are not making a
good connection.
Check for poor connection at
battery and frame. Make sure
connecting points are clean.
Rock clamps back and forth
for a better connection.
Battery clips do not spark
when touched together.
The charger is equipped with
an auto-start feature. It will not
supply current to the battery
clips until a battery is properly
connected. Unlike traditional
chargers, the clips will not
spark if touched together.
No problem; this is a normal
condition.
15. BEFORE RETURNING FOR REPAIRS
15.1 When a charging problem arises, make certain that the battery is capable of accepting a
normal charge. Double check all connections, AC outlet for a full 120-volts, charger clamps
for correct polarity and the quality of the connections from the cables to the clamps and from
the clamps to the battery system. The clamps must be clean.
15.2 When a battery is very cold, partially charged or sulfated, it will not draw 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.
15.3 When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual
and call the customer service number for information. This will usually eliminate the
need for return.
If the above solutions do not eliminate the problem, or for information
about troubleshooting, call toll-free from anywhere in the U.S.A.
