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 identified 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 difficulty determining the polarity of the battery
terminals, see the Wicked Smart Tip below, before proceeding.
IF THE BATTERY IS OUTSIDE OF THE VEHICLE
1.) Connect the POSITIVE (Red) battery clamp or eyelet terminal connector to
the POSITIVE (POS,P,+) battery terminal.
2.) 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.
3.) Connect the battery charger’s AC power plug into a suitable electrical
outlet. DO NOT FACE THE BATTERY WHEN MAKING THIS CONNECTION.
4.) When disconnecting the battery charger, disconnect in the reverse
sequence, removing the NEGATIVE first.

WICKED SMART TIP
HOW TO IDENTIFY THE POSITIVE AND NEGATIVE BATTERY
TERMINALS. The Reverse Polarity Protection feature on the G750 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 G750
IF THE BATTERY IS INSTALLED INSIDE OF THE VEHICLE
1.) 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).
2.) 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.
3: Option A) For Negative Ground Systems, 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.
3: Option B) For Positive Ground Systems, 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.
4.) Connect the battery charger’s AC power plug into a suitable electrical
outlet. DO NOT FACE THE BATTERY WHEN MAKING THIS CONNECTION.
5.) 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.
