PROBLEM
POSSIBLE CAUSE
SOLUTION
Short or no start cycle
when cranking engine.
Failure to wait 3 minutes (180 seconds)
between cranks.
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.
Wait three minutes or until the display reads
and the
LED is on.
Check for poor connection at battery and frame. Make sure
connecting points are clean.
Check power cord and extension cord for loose fitting plug.
Check for open fuse or circuit breaker supplying AC outlet.
The internal thermal protector may have tripped and needs
a little longer to close. Wait until it automatically resets and
try again.
On a severely discharged battery, wait for 10 to 15 minutes
in Engine Start mode, to help assist in cranking.
Charger makes a loud buzz. Transformer laminations vibrate.
No problem; this is a normal condition.
Battery % stays low during
charging.
Battery is severely discharged.
Wrong battery voltage selected.
Continue charging battery for two more hours. If problem
continues; call your Snap-on representative.
Make sure BATTERY VOLTAGE switch is properly set for
6V, 12V or 24V selection.
The “Trickle” and “Fast
Charge” rates do not work
on the 24V setting.
Complete charge of a 24 Volt battery is
not a function of this unit.
This charger does not fully charge 24V batteries. It boosts
the voltage to 27.2V and holds the voltage at this level.
Clicking noise from
charger.
Circuit breaker is cycling.
Battery is defective.
Shorted battery clamps.
Severely discharged battery, but
otherwise a good battery.
Reversed connections at battery.
Under certain conditions, this unit has a high capacity and
the circuit breaker protects the unit under these conditions.
If the circuit breaker is cycling often, stop the operation by
pressing the START/STOP button and wait until the unit has
cooled, to return to operation.
Have the battery checked.
Circuit breaker cycles when current draw is too high.
Check for shorted cables and replace if necessary.
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.
Correct the lead connections.
Display shows “
SUL
”
The battery is sulfated.
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.
Engine start does not work. Vehicle drawing more than 300 amps
(6V/12V) and 250 amps (24V).
Failure to wait 3 minutes (180 seconds)
between cranks.
The charger may be overheated.
Battery may be severely discharged.
Crank time varies with the amount of current drawn. If crank-
ing draws more than 300 amps, crank time may be reduced.
When the Engine Start LED 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 60A Rapid rate for
10 to 15 minutes, to help assist in cranking.
