Positive- Grounded Vehicle: Connect the Negative (BLACK)
charger clamp to the Negative (NEG, N, -) ungrounded battery
post. Then, connect the Positive (RED) battery clamp to the
vehicle chassis or engine part (away from the battery). Do not
connect the clamp to the carburetor, fuel lines, or sheet-metal
body parts: connect only to a heavy gauge, stable metal part of the
frame or engine block.
Plug battery charger power cord into grounded AC power outlet
and the Nitro is now ready for the charging process.
The Nitro’s LED indicators will light to show power the charger.
Using the Simple Touch panel, select the battery’s voltage, 6 or 12
Volts, and select the battery type, GEL or Standard.
The Nitro will now automatically assess the condition of your
battery and deliver the optimum charge.
When charging is completed, disconnect power cable from the AC
power and disconnect cables and clamps in reverse order from
which they were connected.
If using the Nitro for maintenance charging, leave charger
connected to the battery and the Nitro will keep your battery at the
optimum level of charge.
If Battery is Outside of Vehicle
Check polarity of battery posts. For top mounted battery
connectors, the positive post (marked POS, P, +) usually has a
larger diameter than the negative battery post (marked NEG, N, -).
For side mounted battery connections the positive (+) terminal is
RED and the negative (-) terminal is BLACK.
