Charging Your Battery

Charging your battery in the vehicle:

1. Arrange the power cord and charging leads care

fully in order to avoid damage that could be caused

by the hood, door, or moving engine parts.

Keep clear of the fan blades, belts, pulleys, and

other parts that can cause injury.

Check the polarity of the battery posts using the
identification marks on the battery case: POSITIVE
(POS, P, -I-) and NEGATIVE (NEG, N, -).
Identify which battery post is grounded or con
nected to the chassis. THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS GROUNDED.

To charge a negative grounded post system:
Connect the red (POSITIVE) charger clamp to the

ungrounded POSITIVE (POS, P, -i-) 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: Wearsafety glasses and face away

from the battery while making connections.

Connect the clamp to the battery post and twist or
rock back and forth to make a solid connection.

This will help keep the clamps from slipping off the

posts and causing sparks.

7. Set the VOLT/AMP SELECTOR switch and timer

switch to the OFF position. Next plug the power
cord into a grounded AC outlet.
Set the VOLT/AMP SELECTOR switch to the
desired charge time, from 30 to 135 minutes. If

more than 135 minutes of charging time is needed,

the HOLD position can be used. When using the
HOLD feature, the battery being charged must be
monitored closely to avoid over charging.
Set the TIMER to the desired charge rate. (See
"Setting the Controls” on pages 7 and 8, and
“Calculating Charge Time” on page 11.)

10. When the battery is fully charged in the MANUAL

mode, the AMMETER pointer will fell to about half

the selected charge rate. The BATTERY TEST will

be in the green area of the meter. For specific
positions, see the “Setting the Controls” section on
pages 7 and 8.
