Position yourself and free end of cable as far away from battery as possible – then connect NEGATIVE
7.4
(BLACK) charger clip to free end of cable.
Do not face battery when making final connection.
7.5
When disconnecting charger, always do so in reverse sequence of connecting procedure and break first

GROUNDING AND AC POWER CORD CONNECTIONS

This battery charger is for use on a nominal 120 volt circuit. The charger must be grounded, to reduce the
8.1
risk of electric shock. The plug must be plugged into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances. The plug pins must fit the receptacle (outlet). Do not use
with an ungrounded system.
DANGER: Never alter the AC cord or plug provided – if it does not fit the outlet, have a proper grounded
8.2
outlet installed by a qualified electrician. An improper connection can result in a risk of an electric shock
or electrocution.
USING AN EXTENSION CORD
8.3
The use of an extension cord is not recommended. If you must use an extension cord, follow these
guidelines:
• Pins on plug of extension cord must be the same number, size, and shape as those of plug on charger.
• Ensure that the extension cord is properly wired and in good electrical condition.
• Wire size must be large enough for the AC ampere rating of charger, as specified:
Length of cord (feet)
AWG* size of cord
*AWG-American Wire Gauge

10. CONTROL PANEL

DIGITAL DISPLAY
The Digital Display gives digital indication of voltage or % of charge. It also gives Cool Down time
remaining during Engine Start. The display will show the battery voltage or % of charge under certain
conditions. First, when connected to a battery but not charging, battery voltage as measured at the
battery clamps will be displayed. When charging begins, the display will automatically change to display
On to indicate charging has started and then either 6 or 12, the voltage type of the battery determined
by the charger. If the battery voltage is low, the display will continue to show On until the voltage type
is determined. % of charge is an option only after the voltage type, 6 or 12 is determined, and also only
for the Charge rate. It will display for 10 seconds and cycle with the battery voltage display every 10
seconds. When the battery is fully charged, indicated by the Charged/Maintaining (green) LED lit, the
display and all other LEDs will turn off to conserve energy during Maintain mode.
LED INDICATORS
Digital Display LEDs:
% – The Digital Display shows an estimated charge percentage of the battery connected to the charger
battery clamps.
Voltage – The Digital Display shows the voltage at the charger battery clamps, in DC volts.
Charging Status LEDs:
CHARGING (yellow/orange) LED lit: The charger is charging the battery.
CHARGED/MAINTAINING (green) LED lit: The battery is fully charged and the charger is in maintain mode.
NOTE: The display and all other LEDs will be off when this LED is lit, to conserve energy.
