Charging Your Battery

Charging a battery in the vehicle:

1. Arrange the power cord and charging leads carefully

to avoid damage that could be caused by the hood,
door, or moving engine parts.

2. Keep clear of fan blades, belts, pulleys, and other

parts that can cause injury.

3. Check the polarity of the battery posts as indicated

on the battery case: POSITIVE (POS, P, or +) and
NEGATIVE (NEG. N or -). NOTE: The positive post
on top-post batteries is usually larger than the
negative post.

4. Identify which battery post is ground or connected

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) battery charger clamp
to the ungrounded POSITIVE (POS, P, +) post of
the battery. Then connect the black (NEGATIVE)
clamp to a heavy, unpainted 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) battery charger
clamp to the NEGATIVE (NEG, N, -) ungrounded
post of the battery. Then connect the red
(POSITIVE) clamp to a heavy, unpainted metal part
of the chassis or engine block. 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.

The percent of charge scale is intended as a visual aid to help
simplify reading the state of charge of the battery. The meter
is scaled for use with the 10 amp charge rate only. For the
2 amp charge rate use the red triangle. The percent of charge
is based on current drawn by the battery. For this reason
accuracy will vary with the size and battery type.

Using Your Battery Charger

For best results from your battery charger, learn to use it properly. This section tells how to set the controls and how
to charge a battery in or out of the vehicle.

Setting the Controls

SELECTOR SWITCHES:

A 2-way switch is used to select the 2-AMP or the
6-AMP charge rate.

AMMETER:

The AMMETER indicates the measured amount of amperes
being drawn by the battery. When you first start charging a
battery, the reading will be high, with the needle near 6 using
the 6 amp charging rate. As the battery charges, the needle
will fall to about 2 or 3 amps, indicating a charged battery.

At the 2 amp charging rate, as the battery charges the needle
will fall to about 3/4 to 1 amp indicating a charged battery.
