CONNECTING TO THE BATTERY
Before you connect to the battery, make sure that the AC power plug is
not connected to an electrical outlet. DO NOT CONNECT THE BATTERY
CHARGER AC POWER PLUG TO THE ELECTRICAL OUTLET UNTIL
ALL OTHER CONNECTIONS ARE MADE. Make sure you have identied
the correct polarity of the battery terminals on the battery. The POSITIVE
battery terminal is typically marked by these letters or symbol (POS,P,+). The
NEGATIVE battery terminal is typically marked by these letters or symbol
(NEG,N,-). If you are having difculty determining the polarity of the battery
terminals, see the Wicked Smart Tip below, before proceeding.
FOR BATTERIES OUTSIDE OF THE VEHICLE
Connect the POSITIVE (Red) battery clamp or eyelet terminal connector to
the POSITIVE (POS,P,+) battery terminal.
Connect the NEGATIVE (Black) battery clamp or eyelet terminal connector
to the NEGATIVE (NEG,N,-) battery terminal. If you have accidentally reversed
the polarity, an ERROR LED (Orange) will illuminate. The battery charger has
an internal safety feature to protect the battery charger from damage if this
situation should occur. Reverse the connections to clear the ERROR LED and
proceed to the next step.
Connect the battery charger’s AC power plug into a suitable electrical outlet.
DO NOT FACE THE BATTERY WHEN MAKING THIS CONNECTION.
When disconnecting the battery charger, disconnect in the reverse
sequence, removing the NEGATIVE rst.
USING THE G4
WICKED SMART TIP
HOW TO IDENTIFY THE POSITIVE AND NEGATIVE BATTERY
TERMINALS. The Reverse Polarity Protection feature on the G4 is
enabled even when the AC power plug is not connected. MAKE SURE
THE AC POWER PLUG IS NOT CONNECTED TO AN ELECTRICAL
OUTLET. Connect the battery clamp or eyelet terminal connectors to the
battery terminals. If an ERROR LED (Orange) illuminates, the battery
connections are reversed (positive to negative, and vice versa). If the
ERROR LED (Orange) DOES NOT illuminate, the battery connections
were made correctly. In either case, you will be able to identify the polarity
of the battery terminals. Make sure to make a note of it.
USING THE G4
FOR BATTERIES INSTALLED INSIDE OF THE VEHICLE
Position both the AC power plug and battery clamps or eyelet terminal
connectors to avoid accidental damage by moving vehicle parts (i.e. hoods,
doors) or moving engine parts (i.e. fan blades, belts, pulleys).
Determine the vehicle’s battery system. If the POSITIVE (POS,P,+) battery
terminal is connected to the vehicle chassis, then the vehicle has a Positive
Ground System. If the NEGATIVE (NEG,N,-) battery terminal is connected to
the vehicle chassis, then the vehicle has a Negative Ground System. Negative
Ground Systems are the most common.
For , connect the POSITIVE (Red)
battery clamp or eyelet terminal connector to the POSITIVE (POS,P,+)
battery terminal. Next, connect the NEGATIVE (Black) battery clamp or eyelet
terminal connector to the vehicle chassis. DO NOT CONNECT TO THE
CARBURETOR, FUEL LINES, OR THIN, SHEET METAL PARTS. MAKE THE
CONNECTION TO THE ENGINE BLOCK OR A HEAVY GAUGE METAL PART
OF THE FRAME.
For , connect the NEGATIVE (Black)
battery clamp or eyelet terminal connector to the NEGATIVE (NEG,N,-)
battery terminal. Next, connect the POSITIVE (Red) battery clamp or eyelet
terminal connector to the vehicle chassis. DO NOT CONNECT TO THE
CARBURETOR, FUEL LINES, OR THIN, SHEET METAL PARTS. MAKE THE
CONNECTION TO THE ENGINE BLOCK OR A HEAVY GAUGE METAL PART
OF THE FRAME.
Connect the battery charger’s AC power plug into a suitable electrical outlet.
DO NOT FACE THE BATTERY WHEN MAKING THIS CONNECTION.
When disconnecting the battery charger, disconnect in the reverse
sequence.
WICKED SMART TIP
Positive Ground Systems are not very common nowadays. They
are typically found on vintage cars (i.e. classic cars) and tractors
manufactured before the early 1970’s. The reason for the conversion
to Negative Ground Systems was primarily due to the battery corrosion
that accumulated on the positive battery terminals. It was believed that
Positive Ground Systems suffered from increased battery corrosion
due to the opposite polarity since anodes have an oxidation reaction
and cathodes have a reduction reaction. In a battery, the cathode is the
positive.
