OPERATING INSTRUCTIONS12.
Automatic Voltage Detection
When the charger is connected to a battery, it will automatically determine
whether the connected battery is a 6 Volt battery or a 12 Volt battery. This
eliminates the possibility of using the wrong voltage setting.
Automatic Temperature Compensation
The charger adjusts the maximum charge voltage and maximum maintain
voltage based on the ambient air temperature. This permits optimum charging
and safety.
Thermal Runaway
Automatically stops charging to prevent battery from overheating.
Charging
Ensure that all of the charger components are in place and in good 1.
working condition, including the plastic boots on the battery clips.
Connect the battery following the connection instructions described in 2.
Using the Quick-Disconnect Cable Connectors section.
ConnecttheACpowerfollowingtheprecautionslistedinSection8.3.
If you’ve connected everything correctly, the CHARGING 4. (yellow)
LED should be lit indicating that the charger is charging. If the CHARG-
ING (yellow)LEDdoesnotlight,checktheconnectionsorhave
the battery checked/replaced.
Using the Quick-Connect Cable Connectors
Connect either of the two output cable assemblies to the charger in seconds.

RING TERMINALS: The ring connectors permanently attach the battery provid-
ing easy access to quickly charge your battery. This application is appropri-
ate for motorcycles, lawn tractors, ATV’s and snowmobiles. To permanently
attach it to a battery, loosen and remove each nut from the bolts at the battery
terminals.Connecttheredpositiveringconnectorringtothepositive(POS,

Take care to keep both wires and plug away from metal and the engine hood.
Connect the ring connector cable assembly to the charger.
Aborted Charge
If charging can not be completed normally, charging will abort. When charging
aborts, the charger’s output is shut off, and the CHARGING (yellow)LED
will blink. To reset after an aborted charge, either disconnect the battery or
unplug the charger.
Desulfation Mode
If the battery is left discharged for an extended period of time, it could become
sulfated and not accept a normal charge. If the charger detects a sulfated bat-
tery, the charger will switch to a special mode of operation designed for such
batteries.
Completion of Charge
Charge completion is indicated by the CHARGED (green)LED.When

MAINTENANCE INSTRUCTIONS14.
Before performing maintenance, unplug and disconnect the battery charger 14.1
(seeSections6,7and8).
After use, unplug the charger and use a dry cloth to wipe all battery corro-14.2
sion and other dirt or oil from the terminals, cords, and the charger case.
Ensure that all of the charger components are in place and in good working 14.3
condition, including the plastic boots on the battery clips.
Servicing does not require opening the unit, as there are no user-service-14.4
able parts.
STORAGE INSTRUCTIONS15.
Store the charger unplugged, in an upright position. The cord will still con-15.1
duct electricity until it is unplugged from the outlet.
Storeinside,inacool,dryplace(unlessyou’reusinganon-boardMarine15.2
Charger).
Do not store the clips on the handle, clipped together, on or around metal, or 15.3
clipped to cables.
TROUBLESHOOTING16.
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
Charger will not turn on
when properly con-
nected.
AC outlet is dead.
Poor electrical connec-
tion.
Severely discharged, but
otherwise good, battery.
Clips are not making a
good connection to the
battery.
Battery is defective.
Reverse connections at
battery.
Check for an open fuse or
circuit breaker supplying
the AC outlet.
Check the power cord
and extension cord for as
loosettingplug.
The battery may not want
to accept a charge due to
a run-down state. Allow
the charging to continue
until the battery has had
a chance to recover suf-
cientlyenoughtotakea
charge.Ifmorethan20
minutes, stop charging
and have the battery
checked.
Check for poor connec-
tion to battery and frame.
Makesureconnection
points are clean. Rock
clips back and forth for a
better connection.
Have the battery checked.
Unplug the charger and
correct the lead connec-
tions.
Charger makes a loud
buzz or hum.
Transformer laminations
vibrate(buzz).
Shorted Diode Assembly
orOutputRectierAs-
sembly(hum).
No problem, this is a
normal condition.
Have charger checked by
aqualiedtechnician.

abort mode.
See “Aborted Charge”
in the OPERATING IN-
STRUCTIONS Section.
BEFORE RETURNING FOR REPAIRS17.
When a charging problem arises, make certain that the battery is capable of 17.1
accepting a normal charge. Use a good battery to double check all connec-
tions,theACoutletforafull120-volts,the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.
