5. CONNECTING THE BATTERY
1. Identify polarity of battery posts. 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,-).
2. Do not make any connections to the carburettor, fuel lines,
or thin metal parts.
3. Identify if you have a negative or positive grounded vehicle. This can
be done by identifying which battery post (NEG or POS) is
connected to the chassis.
4. For a negative grounded vehicle (most common): connect the RED
POSITIVE jumper clamp first to the positive battery terminal, then
connect the BLACK NEGATIVE jumper clamp to the vehicle chassis or
negative battery terminal (the vehicle chassis is the common choice).
5. For a positive grounded vehicle: connect the BLACK NEGATIVE jumper
clamp first to the negative battery terminal, then connect the
RED POSITIVE jumper clamp to the vehicle chassis or positive battery
terminal (the vehicle chassis is the common choice).
6. When disconnecting, disconnect in the reverse sequence, removing
the negative first (or positive first for positive ground systems).
NOTE:
If battery clamps are incorrectly connected to battery
terminals, the INCORRECT POLARITY WARNING light
will illuminate. Reverse the orientation of the battery clamps.
3. CHARGING MODES (CONTINUED)
Using 13.6V SUPPLY
If not connected with the battery, after starting up the charger is in the power supply mode by default. 13.6V SUPPLY mode provides a current of
7A (constant voltage and constant current). Prior to use, read your 12VDC device manual to determine if it is suitable for use with this mode. As
a power supply, it can also be used to retain a vehicle’s on-board computer settings during battery repair or replacement. Both spark proof and
reverse polarity protection are still able to function normally in this mode. If positive and negative battery clamp touched or connected to each
other, the charger will not generate sparks.
