FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE6.
A SPARK NEAR THE BATTERY
MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE
RISK OF A SPARK NEAR
THE BATTERY:
NEGATIVE GROUNDED SYSTEM
Position the AC and DC cables to reduce the risk of damage by the hood, door 6.1
and moving or hot engine parts. NOTE: If it is necessary to close the hood
during the charging process, ensure that the hood does not touch the metal
part of the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.6.2
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post 6.3
usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chassis 6.4
(vehicle frame). If the negative post is grounded to the chassis (as in most
vehicles), see step 6.5. If the positive post is grounded to the chassis,
see step 6.6.
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the 6.5
battery charger to the POSITIVE (POS, P, +) ungrounded post of the battery.
Connect the NEGATIVE (BLACK) clip to the vehicle frame or engine block at a
distance away from the battery. Do not connect the clip to the carburetor, fuel
lines or sheet-metal body parts. Connect to a heavy gauge metal part of the
vehicle frame or engine block.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the 6.6
battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery.
Connect the POSITIVE (RED) clip to the vehicle frame or engine block at a
distance away from the battery. Do not connect the clip to the carburetor, fuel
lines or sheet-metal body parts. Connect to a heavy gauge metal part of the
vehicle frame or engine block.
Connect charger AC supply cord to electrical outlet.6.7
When disconnecting the charger, turn all switches to off, disconnect the AC 6.8
cord, remove the clip from the vehicle chassis and then remove the clip from
the battery terminal.
