PROBLEM
|
POSSIBLE CAUSE
|
SOLUTION
|
|
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.
Meaning, the clips will not spark if touched together.

|
|
The
charger is making an audible clicking sound (continued).
|
Shorted
battery cables or clips.
|
Circuit
breaker cycles when current draw is too high. Check for shorted cables
or clips and replace if necessary.
|
|
Severely
discharged battery, but otherwise it is a good battery.
|
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 sufficiently
to take a charge. If more than 20 minutes, stop charging and have the
battery checked.
|
|
Reverse
connections at battery.
|
Shut
the charger off and correct the lead connections.

|
|
Short
or no start cycle when cranking engine.
|
Drawing
more than the Engine Start rate.
|
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.
|
|
Failure
to wait 3 minutes (180 seconds) between cranks.
|
Wait
3 minutes of rest time before the next crank.
|
|
Clips
are not making a good connection.

may be severely discharged.
|
On
a severely discharged battery, charge for 10 to 15 minutes in the
10◄►25 amp charge rate to help assist in cranking.
|
|
Charger
will not turn on when properly connected.
|
AC
outlet is dead.
|
Check
for open fuse or circuit breaker supplying AC outlet.
