7.7 For a negative-grounded vehicle, first connect the POSITIVE (RED) charger clamp to the
POSITIVE (POS., P, +) ungrounded post of the battery. Then connect the NEGATIVE (black)
clamp from the charger to the NEGATIVE (NEG., N, –) post. Do not connect the clamp to the
carburetor, fuel lines, or sheet-metal body parts. When disconnecting the charger, turn all
switches to OFF, disconnect AC cord, and remove the NEGATIVE clamp and then the
POSITIVE clamp.
7.8 For a positive-grounded vehicle, connect the NEGATIVE (BLACK) charger clamp to the
NEGATIVE (NEG., N, –) ungrounded post of battery. Then connect the POSITIVE (RED) clamp
from the charger to the POSITIVE (POS., P, +) post. Do not connect the clamp to the carburetor,
fuel lines, or sheet-metal body parts. When disconnecting the charger, turn all switches to OFF,
disconnect AC cord, and remove the POSITIVE clamp and then the NEGATIVE clamp.
CAUTION: WHEN THE POSITIVE (+) POST OF THE VEHICLE BATTERY IS GROUNDED,
DOUBLE CHECK THE POLARITY.
8. CHARGER CONNECTION FOR A BATTERY NOT IN THE VEHICLE
If necessary to remove the battery from the vehicle or equipment, always first remove the
grounded terminal from the battery.
WARNING: To prevent a possible arc, make sure all vehicle loads are OFF.
FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE OF THE VEHICLE. A SPARK
NEAR THE BATTERY MAY CAUSE AN EXPLOSION. TO REDUCE RISK:
8.1 Check the polarity of the battery posts. The POSITIVE (POS., P, +) post usually has a larger
diameter than the NEGATIVE (NEG., N, –) post.
8.2 Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS., P, +) post of the battery.
Then connect the NEGATIVE (BLACK) charger clamp to the NEGATIVE (NEG., N, –) post of the
battery.
