Charging Your Battery
Charging your battery in the vehicle:
1. Arrange the power cord and charging leads
carefully in order to avoid damage that could be
caused by the hood, door, or moving engine parts.
2. Keep clear of the fan blades, belts, pulleys, and
other parts that can cause injury.
3. Check the polarity of the battery posts using the
identification marks on the battery case: POSI-
TIVE (POS, P, +) and NEGATIVE (NEG, N, -).
4. Identify which battery post is grounded or con-
nected to the chassis. THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS GROUNDED.
5. To charge a negative grounded post system:
Connect the red (POSITIVE) charger clamp to the
ungrounded POSITIVE (POS, P, +) post of the
battery. Next, connect the black (NEGATIVE)
clamp to an unpainted, heavy metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines, or
sheet metal parts.
To charge a positive grounded post system:
Connect the black (NEGATIVE) charger clamp to
the ungrounded NEGATIVE (NEG, N, -) post of
the battery. Then connect the red (POSITIVE)
clamp to an unpainted, heavy metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines or
sheet metal parts.
IMPORTANT: Wear safety glasses and face away
from the battery while making connections.

6. Twist or rock clamps back and forth to make a
solid connection. This will help make better
contact and help keep them from slipping off and
causing sparks.
7. Make sure the POWER switch is set to the OFF
position. Next plug the power cord into a grounded
AC outlet.
